The roof or cover is the main part of a home, it is what protects us from the elements, the weather, the sun or cold, the wind and danger. More than walls, a roof over our heads is an indispensable protection for humans. We feel vulnerable before the open sky.
There are different types of materials for the different roofs: whether they are sheet metal roofs, wooden roofs or covers of any other type, it is necessary to take into account our environment and what challenges could arise when keeping our tiles or roofs in optimal conditions.
For this reason, special care must be taken when building our home, whether we do it ourselves or hire metal roofing contractors and Engineering firms, and even if it is a house that has already been built, the roof or cover is a point that must be checked before making any move, check the conditions of waterproofing, insulation and interior finishes, and make the necessary adjustments before any stuff.
In this article, we present you with some cheap building materials for ceilings, both indoors and outdoors… and some ideas to make them look beautiful. Don’t miss it!
An important element of the family home is the roof, and the upper deck; Since it is this part that protects it, it provides security to its tenants from inclement weather, sun and night. The deck is the part that literally provides a roof for the home.
The shapes, designs and materials of roofs are many, and for that reason, we decided to explain in detail some types of roofs and materials for modern roofs.
You can build a beautiful gabled roof without the need for huge hulks of steel or expensive wood framing. The resistance of this structure consists of the sum of the trusses under the plates. This structure is perfect for a tile roof or complete tiled houses.
This option consists of assembling aluminum metal profile trusses, it is an extremely light material that can perfectly load sheets of special gypsum cardboard for exteriors, which are insulated and waterproofed and are perfect as a structure for roof sheets or any shingle roof.
An effective option for terraces or for service patios and roof terraces is to install a metal profile structure, it is very light and easy to place, by means of angles that are anchored to the walls or side fences. On them, which should be no more than 60 centimeters apart, the acrylic plates are placed or, if you want, you can also place ceiling sheets.
Wooden structures clad with wooden battens or plates are classic for their ease of installation and cost, since cheap and resistant wood such as seasoned pine is used.
The idea of an inexpensive wooden cover is to leave the structure exposed so that it does not look so rustic, if it is not to your taste, you can paint it in a neutral color, either white or cream, to blend in with the pieces and beams with the full clear. Do not forget the exterior waterproofing, it is essential.
If it is a small bedroom, a ceiling like the one in the photo always adds a little more space visually to the room.
Mud brick is a very noble, welcoming, warm, beautiful and structurally reliable material under certain circumstances. One of them is the work of roof vaults. The shape of the brick found on joists gives it support and strength, in addition to generating an original design and adequate management of light and climate. It goes without saying that brick is one of the most economical materials on the market for modern structures and roofs.
Like the construction of the previous point, in this case the vault has received a coat of paint to enhance the style and color of the place. It is a good decorative resource to draw attention to the brick walls or the tile roof, the wooden floor, or the art on the walls, or simply to reflect the natural light that enters through the windows.
Leaving the structure apparent, this roof is excellent for terraces or extensive galleries of the house. It is a very simple structure with wooden beams and thin bars every 60 centimeters, with a slope of 2 or 4 waters. Clay tiles sit directly on the structure, or they can be made of shingles with small wooden plates set on top of the other. It gives a fresh and cozy atmosphere to the place with all types of tile roofs.
Modern roofs on patios and terraces can be very economical and have simple structures since they are not supposed to carry machines or weights of any kind.
A good option is to build a structure with steel beams, a grid with columns and sides, and angles in the middle. On this structure, some planks or thin bars can be placed crosswise and on them secure reeds or small sticks of dry cane or bamboo to protect from the sun without limiting light or ventilation.
A variant of the previous structure is to place fabrics instead of acrylic, and in such a way that they can be retracted and allow the sun to enter or closed and prevent sunlight. One of its benefits is that the fabrics can be easily replaced or removed, washed, reattached and tensioned to function properly. Modern ceilings love fabrics!
Although concrete is not the most economical material for many types of roofs, it can be considered as such as long as it is used in a monolithic structure with the indicated steel and without major finishes.
The idea is that the slab towards the interior is shown bare, leaving the electrical installations apparent by means of rails and supported cables. The outside must be properly insulated and waterproofed. By not having soffits, ducts and interior finishes you can save a good sum of money, and use it to install modern industrial-style luminaires, doesn’t that sound better? If you want something similar but cheaper, you can do a combination of concrete and roofing sheets.
This slab consists of a steel and concrete reinforcement forming a series of transversal and longitudinal beams, and between them, the insulating material, preferably polystyrene, is placed. Below and laterally, wooden falsework must be placed, for the enclosures and to load the slab. If you like houses with tiles, a slab of this style could serve as a base.
This cover can work on its own as a roof sheet structure or as a ceiling light, due to the versatility of its material, design and format. It is perfect for giving a home an industrial or contemporary touch, where a series of steel beams hold corrugated sheet plates in the design of your choice.
It is necessary to cover the structure with special paint for roof sheets, anticorrosive and non-toxic since it will be inside the residence. On the outside, you must ensure precise waterproofing for the region. Run to tell your trusted architect about your projects and the vision you have for your home!

You may easily incorporate thermal mass into a building for passive solar heating by using materials such as concrete, stone floor slabs, or masonry partitions that hold, then slowly release heat. If you really want to go super green, you can even built with mud floors!
You can also generate mass for storing heat by building sun facing trombe walls. Trombe walls can be made of adobe (a very popular and green material often used here in the Southwest), rammed earth, concrete, stone, or even water tanks.
Orienting your building so that the longest walls run from east to west, and using large south-facing windows, allows the sun to help heat the home in winter. Properly designed roof overhangs shield the building interior from the summer sun. Passive solar designs use natural methods to stabilize the internal temperature of a building without the need for active mechanical devices such as pumps or fans, although these may be used to supplement performance. Passive solar designs also include natural ventilation for cooling. An obvious method is simply locating windows in the building strategically so that when opened, a natural breeze may be easily accelerated in the interior. Openings and passages designed into ceilings will promote the escape of hot air from the interior of the building through the roof or upper windows.
Estimated Cost Savings:
Passive solar designs can reduce heating bills as much as 50 percent. For a monthly heating bill of $200 dollars, you may expect savings of $80-$120 per month. If passive solar features are included at the time of initial construction, or as part of an overall remodeling effort, the effective net cost of improvements will be much lower. However, you will benefit immediately in your monthly cash-flow.
Passive solar designs are easiest to implement at the planning and design stages of a new home. However, existing buildings may be quite easy to retrofit with passive solar improvements. Virtually all occupants of passive-solar homes report enjoying design features, improved efficiency, and an enhanced sense of connectedness to the natural world.
People here in Albuquerque and other Southwestern communities have been building with passive solar designs for hundreds of years. Ancient adobe homes attest to this long-held building tradition in New Mexico. When most people think of New Mexican architecture or building, adobe structures often come to mind. With Albuquerque's beautiful sun-filled skies, designing for passive solar is a cost-effective and relatively simple green heating and cooling solution.

CDD Ltd were appointed to undertake RC Detailing of all concrete elements including the heavily reinforced bases and walls from the pile caps, through to the slabs, beams and columns.
Planning was obtained in January 2017 for a 215,000 tonne per annum facility to provide a replacement Combined Heat Power Plant (CHP) facility to support the Earls Gate Energy Centre (EGEC).
CDD had worked extensively with this client before over a number of years, so we were already familiar with this type of project, but this one was a particularly ambitious one which can bring many challenges which our experience helped with. The intention was to provide a high quality residual waste solution built using the best available proven technology in the world.
The heat and power generated by the plant was to be used to support four different chemical operators in the Earls Gate site. The plant was replacing an old gas fired plant with the heat and power off-take making the Earls Gate plant one of the most efficient in the UK, helping to drive the shift from fossil fuels to heat and electricity from renewable sources. This type of project particularly appeals to us as it combines years of experience with a passion for integrating new systems, which always needs significant contemplation on how everything will work together once built and it’s always a pleasure to see the end result in operation.

WTOP News explains why the Chesapeake Bay Bridge was such a wonder when it was created and why it remains to be today. It said, "In 1947, the General Assembly, under the leadership of Governor Lane, passed legislation to begin bridge construction."
According to WTOP News, construction on the bridge began in 1949 and opened to traffic on July 30, 1952. The construction cost was $45 million and at that time, it was the longest continuous over-water steel structure and third longest bridge in the world.
Many motorists traverse the bridge daily. It connects the state's rural Eastern Shore region with the urban Western Shore.
Not surprisingly, there are people who must rely on a special service to drive them across the bridge every day to and from work. They have an intense fear of bridges that has only been heightened by this particular bridge.

Most local councils on the NSW coast have entrance management procedures in place where low lying infrastructure is present, and many include being able to artificially open the lake or lagoon to the ocean. This procedure is started when the body of water reaches a 'trigger level' or 'trigger condition', as set out in the relevant management plans.
Many factors affect the Council’s decision to artificial open the lakes. Generally, when performed during wet weather, opening can limit the scour and result in a weak breach and more sand ending up in the entrance channel. As a result, the flood tide delta may expand into the estuary, causing the entrance to close over more quickly (DPIE, 2020).
During dry weather, the local community often calls for the opening of the entrance in a bid to improve perceived poor water quality. This action has very little effect on flushing, does not encourage effective scour, brings more sand into the channel and closes over quickly.
In fact, frequent artificial openings at low trigger levels can cause the entrance compartment to become clogged with sand over time, decreasing the effectiveness of subsequent openings (DPIE, 2020). Coastal experts advise that to maintain a healthy lake, entrance management should be as close to natural as possible.

Final Report on Preserving and Protecting Freight Infrastructure and Routes Published by the Transportation Research Board
Categories: News, Studies
April 19, 2012 - Mark Meitzen
A consortium led by Christensen Associates and including the University of Texas at Austin—Center for Transportation Research; Kathryn H.S. Pett; and Grow & Bruening, PC, won a competitive bid to investigate issues related to freight corridor encroachment. The objective of this 16-month research, funded by theTransportation Research Board’s National Cooperative Freight Research Program (NCFRP), was to provide guidance to public and private stakeholders on how to develop, preserve, protect, and enhance freight transportation infrastructure and routes for all modes of transportation. Examples of encroachment include urban gentrification and incompatible land uses near freight transportation facilities (e.g., rail corridors, truck routes, terminals, and ports,) that create pressures to reduce or constrain freight activities because of noise, vibrations, visual pollution, and emissions impacts.
The TRB issued the final report in March 2012. The report is available on its website.
A summary of the study was featured in TR News, TRB’s bi-monthly magazine, on pages 45 to 49 of the January-February 2013 issue. “Preserving and Protecting Freight Infrastructure and Routes,” by Mark Meitzen, is copyright National Academy of Sciences.

Wood floor tiles blend the strength of porcelain tiles with the natural beauty of hardwood. Moreover, this flooring option is pretty affordable than natural hardwood, is easier to maintain, and comes in a variety of colors, patterns, and designs.
However, most bricklayers are confused about how to install them. After all, proper installation of wood floor tiles is critical in order to reap their full benefits.
The subfloor should be in good condition and of uniform thickness to ensure that the wood floor tiles are adequately laid. It's also worth noting that a flat subfloor is critical for preventing plank tile cracking. You can achieve this by using a leveling compound.


AIRES-CZM - Using AIRborne REmote Sensing for improved Coastal Zone Management
The objective of the EUFAR project AIRES-CZM was to develop a reliable tool to estimate coastal water quality indicators by using remote sensing techniques (both airborne and satellite).
A set of semi-empirical algorithms (based on hyper-spectral airborne and in-situ data for estimating the concentrations of the water constituents) were also developed in addition to the migration of the developed algorithms into the satellite workflow.
The secondary objective was the implementation of an automatic warning system based on satellite imagery processing and the final objective was the inclusion of the information obtained by means of remote sensing in the dataset used for the calibration of regional hydrodynamic models.
The area of the Cantabrian coastal fringe faced the problem of lacking its own specific algorithms to retrieve those water quality parameters derived from remotely-sensed data. Therefore, the main issue addressed in the campain was the development of those regional algorithms. This development required the combination of both airborne and satellite data with information collected in field campaigns.
Start date of project: 19-07-2010
End date of project: 20-07-2010
The investigation took place in the Cantabrian coastal fringe

Fire Hydrant Testing- Chanute
04/16/2018 @ 8:00 am - 5:00 pm
The Chanute Fire Department will be performing annual fire hydrant testing from April 16th, 2018 through July 2, 2018. Chanute firefighters will inspect and test static, residual pressures and flow rate of each of Chanute’s nearly 500 hydrants to ensure that they work properly in the event they are needed.
Residents may notice the following conditions during testing:
- Drop in water pressure
- Slight discoloration of the water
- If citizens notice any discoloration, they are encouraged to open a faucet for a brief period of time until the water runs clear.
Why testing is important:
Testing and recording new valuesSome trucks are able to pump at a rate that exceeds what some hydrants can provide so each hydrant is tested and values are recorded. This helps prevent damage to the hydrant or the truck and equipment.Pressure and new rate testing ensures that adequate water supply. Maintaining adequate water supply can help reduce insurance rates.Flushes sediments from water main pipes and helps enhance water quality.
Any questions about this Annual Testing should be addressed to the Public Works Complex at 620-431-5250
or the Chanute Fire Department at 620-431-5236.

New Construction for Metro Pooch in Guilford, CT
Published on: Monday, October 28th, 2019
Munger is well underway on a large New Construction project for Metro Pooch in Guilford, CT. The 9,600 SF building will be a dog daycare and pet boarding facility for the surrounding area.
Construction for this project is orchestrated by Michael Cormier Jr., Project Manager, and Michael Buydos, Project Supervisor. The foundation and slab pouring was recently completed, along with the exterior walls. Currently, the team is working on wood framing and general site work. The roof trusses are scheduled to be set this week, followed by roofing and siding shortly after.
As the weather gets colder, construction activity will shift to primarily interior tasks, including sheetrock work, HVAC, electrical and finishes. The project is estimated to be completed by Spring of 2020.
Stay tuned for more updates on Metro Pooch!


Wall ties play an essential part of the stability of masonry panels. Houses build before 1978 usually contained wall ties manufactured from galvanised mild steel. These ties were expected to last the lifetime of the building, but for many years it has been recognised that some of these wall ties have corroded after only 15 or 20 years, and this can be accelerated where damp and flooding becomes an issue.
When these ties corrode, they can expand and this causes the brickwork to crack at the mortar joints and can result in major damage and sometimes the collapse of walls.
In most cases we replace the old degraded wall ties with new Neoprene ties. Fashioned from stainless steel with locking brass nuts, these wall ties are ideal for projects that prioritise brickwork. The ridges of the inner-neoprene spreader work with the anti-slip knurled nut, offering superior grip and uninterrupted expansion. For additional protection, a dip ring has been fitted allowing for movement between the two leaves.

In many parts of the world, the fight against traffic congestion is the norm. In most cases, people use a two-pronged approach; reducing the road traffic and enhancing the capacity of the road. CTRMA recommends taking small steps to gain a giant leap into the future of vehicular transport. Having the developed systems of vehicular transport that include the cloverleaf, flyovers, and express lanes is one way to ensure that traffic jams to not become a menace in the roads. Efficient road transport is the key to development in the cities, but the traffic jams choke the roads significantly, causing delays that can be quite expensive. Congestion can make the road transport inefficient, increase environmental pollution, and cause huge losses.
The collection of toll payments is one way to maintain the existing roads while making the necessary efforts to construct more roads. Besides increasing the capacity of the urban roads, the department of transportation can encourage people to use the ring roads or use alternative routes. By establishing some toll stations in the entry points, the municipalities can discourage many motorists from entering the town. Today, most of the modern cities have bike-friendly roads. However, establishing the toll stations forces the motorists to stop. Such stoppages can disrupt the flow of traffic, turning a small challenge to a huge problem. The CTRMA advocates for smart roads that have the ICT sensors. These sensors allow the motorists to pay for these charges electronically, thereby reducing the congestion.
The prospect of creating a smart road entails the collaboration of civil engineers and ICT technicians. Such a partnership can deliver the following benefits:
- Alerting a driver to avoid the congested areas. If the motorists can avoid the congested areas, it is possible to deal with them easily.
- Reducing the amount of pollution in the cities is possible once the motorists avoid the urban roads and prefer the peripheral roads.
- Reducing the congestion is an easy way to save time and money.
- Using the smart roads help the motorists to drive safely and avoid the road accidents.
- Increasing the parking charges in the urban areas helps to discourage the people from driving to the towns unless where necessary.
- The installation of the adaptive traffic control systems and other technological innovations can make the urban roads safe and efficient. A single system that controls the traffic lights while monitoring the prevalent conditions will ease the congestion easily.

The Parish Building has required work on the outside of the building for some time. A team of councillors has been meeting for some years endeavouring to decide how the usefulness of the building to the community can be maximised. Street library was about to close until the Parish Council stepped in by offering the downstairs of the building. There is a need to optimise areas of the building to enable more efficient use of space and more room for the ever-increasing popularity of the library in its new location. There will be a public consultation process as we devise a plan to develop the building to enhance its usefulness.


Northern Virginia is one of the wealthiest areas in the United States, including Arlington, Fairfax, Loudoun, Prince William, counties and the independent cities of Alexandria, Falls Church, Fairfax, Manassas, and Manassas Park. These cities and towns are connected to each other with various transportation means such as railways, roadways, etc.
Northern Virginia has high road congestion rate. The area is counted among the most congested regions in the nation. In order to lessen traffic at gridlock, local governments support other forms of transportation like Metrorail, HOV, carpooling, etc. Northern Virginia Transportation conditions are worsening due to increasing population.
Curvy colonial roads are one of the biggest public transit issues. But the recent renovation of the Woodrow Wilson Bridge near Alexandria that also carries more than 300,000 vehicles everyday into Maryland will double the traffic lanes at that specific narrow area when completed in 2008.

Cause #1: Rain Entering from the Top
Chimneys without covers are susceptible to rainwater falling directly into them. It’s important to install a chimney cover to not only keep rain out but also prevent birds, animals, and debris from entering. The primary benefit of a chimney cover is to keep the chimney clear because blockages can lead to CO poisoning.
Cause #2: Cracks in the Chimney Crown
The chimney crown, the cement part on top of the chimney, is designed to prevent rain and snow from entering around the flue liners. When cracks develop in the crown, water can seep through them and cause leaks. It is crucial to address these cracks to maintain a watertight seal. Learn more about chimney cleaning to keep your chimney in good condition.
Cause #3: Leaks due to Condensation
Gas fumes, especially at lower temperatures, contain a significant amount of moisture. In an oversized or cold chimney, these fumes can condense on the inside, leading to constant moisture on the bricks. The implementation of a chimney liner can effectively resolve this issue and prevent further leaks.
Cause #4: Problems with Chimney Flashing
Flashing is used to prevent water from entering where the brick structure intersects with the roof or comes close to it. If the flashing is not properly sealed, there is a gap that water can easily flow through. Oftentimes, aluminum flashing is used and sealed with waterproof “stuff,” such as tar. While tar is not the ideal choice, it is frequently used for this purpose.
Addressing these common causes of chimney leaks is crucial to maintain a dry and safe chimney system. If you’re facing any of these issues, it’s recommended to consult professionals for appropriate repairs and solutions.


Saint Mark's Bell Tower, Venice | Phto: Peggychoucair via Pixabay
The tower is 98.6 metres tall and was probably used as a watch tower or lightouse. It was renovated many times but, after being seriously damaged by lightning in 1489, the tower assumed its definitive shape thanks to the renovation directed by Bartolomeo Bon the Younger between 1511 and 1514. On the morning of July 14, 1902, the bell tower collapsed completely, also demolishing the Loggetta. The venetians decided to rebuild the tower exactly "as it was and where it was". Today, it is possible to climb the bell tower to enjoy an extraordinary panoramic view of the city.


Californian officials have outlined plans for a 72km tunnel to boost water supplies and help the drought-stricken region combat climate change.
The US state’s Department of Water Resources published a draft environmental impact report detailing its proposals for the new pipeline in the delta region inland from San Francisco.
Under the plans, intake points would be built on the Sacremento River to the north of the Delta area then linked by a 12m-diameter tunnel to Bethany Reservoir further south.
Californian officials said the project was necessary to increase resilience to seismic risk, sea level rise and “other foreseeable consequences of climate change and extreme weather events”.
More than 97% of the state is currently in “severe drought” according to a national monitor, with over half its land suffering from “extreme drought” whereby fires start all year round and water is inadequate for livestock and wildlife.

I’m doing this a little out of order. Why groundwater and erosion first? Modeling the water layer on and in the ground is an isolated section of climate simulation. Whereas the air modeling has interdependent parts (radiation, convection, etc.), the groundwater system is self-contained except for precipitation and evaporation. I can easily implement a dummy precipitation/evaporation system.
Second, the groundwater system is a good warm up for the air modeling. There are a lot of similarities between how water and air layers are modeled: they are both grid systems moving fluids around based on pressure. The water system is much simpler because water is incompressible and water pressure is solely dependent on depth. Water also moves more slowly and there’s less of it.
Feel free to skip to the Results section.
Introduction and Science
Most groundwater is underground in aquifer layers, or zones of saturation. The top of the aquifer is referred to as the water table. Despite how they are often depicted, aquifers are generally not underground rivers. They’re really layers of porous rock, like a layer of sponge between layers of non-porous rock. As you might imagine, it takes a long time for water to move through these porous rock layers, sometimes with speeds on the order of centimeters per year.
In some areas, the water table is above the surface of the ground. Then you get surfacewater, like rivers and lakes. Rarely, when the surface is non-porous, surfacewater can occur even when the water table is far below ground. Water aboveground moves much faster, up to the order of meters per second. Note: Surfacewater is not a word but that’s what I’ll call all water aboveground.
I have three goals for the groundwater and erosion system.
Rivers and Lakes
I want to generate rivers and lakes from the groundwater simulation. This gets a little tricky due to the extremely low resolution of my map. For example, if my tiles are 50 km wide, then I can’t realistically model rivers, since rivers are much narrower than 50 km. So I’ll have to use some heuristics and hand-waving to draw rivers from my groundwater simulation. Still, a chain of adjacent tiles with lots of surface water flowing over them should create a river, and tiles with a large amount of standing water should be lakes.
I’d like the erosion system to create river basins. As mentioned above, this may be tricky due to the low resolution of the map.
When I do biome identification, I’d like to use the groundwater system to identify areas saturated with water as wetlands. This isn’t very important because I can always just fall back on using the precipitation levels to identify wetlands.
All right, let’s look at some literature on computational erosion models.
Most of my model is based on:
Xing Mei, Philippe Decaudin, Bao-Gang Hu. Fast Hydraulic Erosion Simulation and Visualization on GPU. Marc Alexa and Steven J. Gortler and Tao Ju. PG ’07 – 15th Pacific Conference on Computer Graphics and Applications, Oct 2007, Maui, United States. IEEE, pp.47-56, 2007, Pacific Graphics 2007. <10.1109/PG.2007.15>. https://hal.inria.fr/inria-00402079.
I’ll try to write everything out so you don’t need to read the paper, as I do have some differences, but I still recommend reading the paper (and some of its references). It’s a pretty easy read.
A much older paper that’s also relatively readable:
F. Musgrave, C. Kolb, and R. Mace. The Synthesis and Rendering of Eroded Fractal Terrains. Computer Graphics, Vol. 23, Num. 3, Jul 1989.
The Model Design
At each tick, the following is calculated:
- Precipitation adds to surface water
- Evaporation subtracts from surface water
- Surfacewater drains into groundwater if there is room
- Excess groundwater is moved to surfacewater
- Lateral surfacewater movement. At each tile:
- The outflow velocity in all four directions is calculated based on pressure differential
- Outflow velocities are capped at a speed limit
- Water height is recalculated from the sum of all outflows and inflows
- Lateral groundwater movement is similar to surfacewater movement
- Sediment is picked up or deposited at each tile based on the current dissolved sediment compared to the sediment capacity
- Lateral sediment movement is calculated using a semi-Lagrangian approach
I store surfacewater and groundwater as heights since it’s trivial to calculate the volume by multiplying by the constant tile area.
Precipitation and Evaporation
For now, I’ll use a trivial precipitation and evaporation system. Eventually (not in this post) this will be replaced with a full water cycle simulation.
The water layer itself will have two sublayers: groundwater and surfacewater. Rain (for now I’m not considering frozen precipitation) is all added to surfacewater.
The groundwater sublayer has a maximum amount of water it can store. If the groundwater in a tile ever exceeds its maximum capacity, the excess groundwater is immediately moved to the surface. This models when the water table is higher than the ground.
If the groundwater in a tile is below the tile’s groundwater capacity, then any surfacewater slowly drains into the groundwater layer. The exact function governing the speed of draining can be experimented with.
Note: Currently I have a constant groundwater sublayer capacity. I don’t do very much with it. In the future, if I do more underground modeling, I’d like to have it conform to the following image, where the bottom depth of the aquifer is independent of local changes in elevation.
Lateral Water Movement
This is the complicated bit for which I recommend also reading the “Fast Hydraulic Erosion” paper. I’ll explain the simulation for surface water first.
All the tiles are treated as closed tanks connected by pipes. The pipes connect the bottom of the tanks.
The velocity in the pipes is governed by the pressure differential between the tiles. Water pressure is governed by the height of water above it:
I care about the difference in water pressure. In this scenario, the difference in water pressure depends solely on the difference in the height of the water in the two adjacent tiles. Note that this height difference includes any difference in the ground elevation.
where each h is the sum of the terrain elevation and the surface water height.
At time t = 0, the velocity in every pipe starts at 0. After t = 0, the pipe velocity is accelerated by the pressure differential. The velocity update equation for a pipe is:
where l is the pipe length, which is the side length of a tile
I only want the outflow, so I’ll remove negative velocities. Inflows will be calculated from adjacent tiles’ outflows.
There’s a problem: what if my total outflow exceeds the amount of water on the tile? In this case I need to scale down all the outflow from the tile (this is why I focus on calculating outflows at every tile). From the pipe velocity, I can calculate the amount of water transferred between tiles during a tick.
where Q is the volumetric flowrate and A is the pipe cross-sectional area
Note: The pipe cross-sectional area A is an arbitrary parameter (since these are imaginary pipes). It is useful to control how fast water moves around in the simulation. Reducing the pipe area size is useful for offsetting some of the undesirable effects of having such large tiles.
So if , I need to scale down all four outflows by a factor of at least .
At each tick, the water height at each tile is changed by adding the total inflows from adjacent tiles and subtracting the outflows from the current tile.
Groundwater lateral movement is much the same, except it has a much smaller pipe area to simulate the filtering effect and slow movement of groundwater.
Finally, whenever water flows into the ocean, it’s destroyed. I don’t run any groundwater simulation on ocean tiles.
Sediment Dissolution and Deposition
Whenever surfacewater is present on a tile, the surfacewater can either pick up or deposit sediment. The sediment capacity of the surfacewater on Tile(x,y) is given by the following equation:
where is the sediment capacity (solubility limit) constant, is the local tilt angle (between 0 and ), and is the horizontal water speed.
As you can see, the sediment capacity increases when the terrain is steeper and when the water velocity is higher. This has an issue where very flat terrain has nearly zero erosion. I can fix this by adding a minimum sediment capacity.
Note: At this point, I diverge a bit from the Fast Erosion paper. Their deposition/dissolution equations don’t take into account the timestep , which I am unable to explain.
At each tile, if the suspended sediment exceeds the sediment capacity , then sediment is deposited. If , then sediment is dissolved. Therefore, the change in suspended sediment is given by:
where K is like a dissolution rate constant (Note: the paper uses separate constants for dissolution and deposition, whereas I use the same constant)
Note: Although the exponential function is expensive, it is independent of the location, so it only has to be calculated once per tick.
This change in sediment is added to the suspended sediment and subtracted from the tile elevation. There is some leeway here in how exactly the sediment concentration is tracked and converted to elevation. For the most Science, the actual amount of sediment should be tracked and converted to elevation in order to keep this step mass conservative. I used a less rigorous approach that let me exaggerate the elevation changes to speed up the erosion process.
Sediment Movement: Semi-Lagrangian
Despite the fancy name, this method is actually very simple. This is again the approach taken by Mei et al.
To model the movement of sediment dissolved/suspended in water, at every tile I take an Eulerian step back in time. Basically, I travel backwards along the tile’s water velocity vector and take the sediment value from there.
At Tile(x = 5, y = 3), if the timestep is 1 second and the water velocity at the tile is (1, 2) m/s.
Eulerian step back in time: . So the sediment value at Tile(5,3) at is whatever the sediment value was at Tile(4, 1) at . Since the Eulerian step back in time usually does not result in perfect integer coordinates, the sediment value is interpolated from the surrounding tiles.
Note: As always, this step needs a “speed cap” to prevent instabilities (ideally the Eulerian step back in time would always be less than a full tile. Definitely don’t want it to move 50 tiles at at time). As long as the speed cap from the water flow rate section is low enough, I don’t need to add another one here.
Results and Troubleshooting
I apologize for using the same rendering color for both surfacewater (rivers, lakes) and shallow ocean (continental shelves). Also, as a note, I’m rendering surfacewater where the volumetric flowrate over a tile is greater than an arbitrary threshold. This is not necessarily the best way to identify rivers/lakes.
This is the first stable version of the erosion simulation. The mountainsides are looking pretty eroded. It’s not perfect, but, given the tile size involved, I think that’s the best I can hope for. There are a couple of issues though.
First, the plains and the central mountain areas aren’t getting very eroded. There are a few levers I can pull to alleviate this. The easiest one is to increase the minimum sediment capacity so that slow-moving water over flat areas will carry more sediment.
Yikes. After some experimentation, it seems that whole continents will erode before the hint of a river will manifest in the flatter areas. This requires a bit more careful analysis.
There are a few things going on here. First, water is rushing very fast down the sides of the mountains, then it gathers at the foot of the mountain ranges, but it doesn’t make it out to sea.
The water rushing down the mountainsides probably indicates that my maximum water velocity is too high.
After going back and comparing units, it turns out that my maximum water velocity is over 200 m/s, which is indeed too high. I’ll reduce it to a more realistic 5 m/s. Also, I’m naively capping the x-velocity and y-velocity independently. This both allows greater diagonal velocity (up to ) and means many too-fast velocities are shifted to a perfectly diagonal direction. Instead, I’ll change the speed cap function to calculate the magnitude of the velocity vector (which unfortunately requires an expensive square root function). These changes reduce the erosion of the mountainsides and increase erosion in the main mountain areas, but they don’t increase erosion in the plains areas.
The water gathers at the foot of the mountain ranges but doesn’t make it out to sea. That means one of two things: either the water is spreading out into a thin, even layer over the plains, or the water is evaporating before it makes it very far. I suspect it’s the latter, since I’m using an arbitrary guess for the evaporation rate. Although, it’s also possible this is an unforeseen symptom of too-large tile sizes. I hope that’s not the case.
According to the many pool owners online, water evaporates at roughly 1/2 cm per day. That translates to 5e-8 m/s. I was using 1e-5 m/s. That’s pretty far off. I’ll update the evaporation rate and tweak the precipitation numbers to keep the simulation stable. Let’s see if the reduced evaporation makes a difference.
Hey, those kind of look like rivers. They are too wide, which likely is partially caused by my massive tile size, and I’ve lost the mountainous rivers, but that’s probably related to my surfacewater-rendering threshold.
After more tweaking of the various constants and occasional debugging and cleaning, it looks like this.
In the above image, rivers/lakes were “detected” by coloring land light blue whenever the surfacewater height was greater than 1 meter.
There is still an issue I would like to investigate: there is a grid artifact (erosion prefers to occur along horizontal or vertical lines, becoming more obvious with a larger sediment dissolution rate constant). This could have a lot of causes. For now, it seems to be minimized by using a low erosion dissolution rate constant and running more ticks.
Also, when I reach the full water cycle and integrate this erosion system, I’ll revisit the river formation to make them look more river-y. I may also need to revisit my mountain generation algorithm to work better with the erosion system.
I’ll start on the climate model with insolation and radiation.

Determining the potential of the wind
wpd has its own in-house onshore "Site Assessment" Department. It consists of meteorologists, environmental scientists, engineers, energy and environmental technicians. Working with our relevant project developers, this team carries out wind measurements at home and abroad in order to make an exact determination of the wind potential and the energy yield in the particular project locations.
To do so, the speed and direction of the wind are measured over a longer period of time – normally at least a year – at the heights at which later the rotor blades of the turbine will "harvest" the wind.
This is done using the latest measuring technology such as wind measurement masts equipped with anemometers and wind vanes, or with the remote detection systems, SoDAR (Sonic Detecting And Ranging) and LiDAR (Light Detection and Ranging).
Based on the wind data thus gained, the team will produce internal reports to support the project management in its strategic planning. There is also an option to estimate the wind energy potential via the yields of existing neighbouring systems.
Before a wind farm is constructed, the data are given to external wind experts who use the measurements to calculate the expected yield, and produce a wind report for the location. In the later course of the project, the external wind reports will form the basis for financing the wind farm and the choice of turbines. The wind information compiled by the site assessment is therefore both technically and financially crucial for the successful planning and implementation of a wind power project.

Difference between Normal Tiles and Concrete PaversDucon Marketing
Are you looking for some help selecting between standard tiles and concrete pavers? Then you have come to the right place. This article will inform you of the differences between these two materials. When it comes to laying a new, durable surface for the house, many products are available. Two of the most popular ones are tiles and concrete pavers. While these two options have several differences, there’s a lot you’ll be able to take advantage of by using either one. Here are some factors you can consider when deciding between the two.
1. Low Maintenance
Concrete pavers are low maintenance and will look great for the life of your driveway. They can be power washed to remove any dirt or grime and resealed to restore their appearance. The joints between each paver can be filled with sand, which helps keep them in place. Over time, the sand will wash out of the joints due to rain and other weather conditions. To maintain their appearance, you need to sweep new sand into the joints every few years.
One of the most significant differences between pavers and standard tiles is that pavers are long-lasting. This is because pavers are made from concrete created by mixing cement and aggregates, such as crushed stones or sand. This makes the pavers extremely durable since they cannot be easily broken like regular tiles.
3. Fire Resistant
Concrete pavers are fire-resistant, as opposed to natural stone tiles, which are not. If you live in a region susceptible to wildfires or brush fires, concrete pavers can protect your home from catching on fire if the fire reaches your house. Concrete pavers are less likely to be damaged by saltwater or saltwater splash than other materials. If you live near a beach or in an area that uses salt on its roads during the winter, consider these pavers for your home.
Concrete pavers are one of the most durable and versatile materials for landscaping. These pavers are made from cement, water, gravel, sand, and other aggregates. They can be used in various applications ranging from driveways to walkways to patios. Concrete pavers come in many different shapes and sizes as well as colors. Concrete tiles have been used for more than a century for both residential and commercial applications.
5. Quick and Easy Installation
Concrete paver installation has become very popular among many homeowners because they are easy to install and maintain. Before you start with the installation process of these pavers, it is essential to know about all the necessary tools required for this job. The most important tool needed for this job is the plate compactor used to compact sand or gravel before installing these pavers on the ground. A plate compactor helps in smoothing out any bumps or irregularities on the surface before starting the installation process.
Concrete pavers are the latest trend in paving and are becoming more popular. Pavers can be customized according to color, texture, depth, and size. Concrete pavers impart a striking appearance to the outdoor area and make it look elegant and expensive. In addition to creating a stunning impression, concrete pavers also prove their worth in functionality as they are low-maintenance products that do not crack or deteriorate quickly. At Ducon Industries — a trusted concrete paver supplier in Dubai, UAE —we manufacture different sizes and shapes of concrete pavers with many patterns and textures.


One of the most enchanting cities of the world is San Francisco. The beautiful Pacific Ocean lends this city its misty and mysterious cover where residents and tourists alike are in awe of its sights and sounds. One of the iconic structures of the world is to be seen here–The Golden Gate Bridge. This bridge connects the City of San Francisco to Marine County. The most photographed bridge in the world is an engineering marvel of its time and was the longest bridge for around 27 yrs after it was built in 1937. Mist and fog from the Pacific Ocean often cover the bridge giving it a mysterious aura. This bridge attracts people from all over the world in all seasons and the wind swept and cloud covered views of San Francisco’s skyline are a million dollar view not to be missed if you venture to this part of the country.
The bridge can be crossed by car, bicycle and even on foot. Driving on the Golden Gate Bridge is an experience in itself. Its 6 lanes are a part of US Route 101 and California Highway 1.
Golden Gate is a suspension bridge designed and built under the able guidance of Joseph Strauss. It stands as the symbol of recognition for the city of San Francisco and even California. Seen here is the city of San Francisco as a backdrop to the bridge on a clear sunny day.
The 1.7 miles of the bridge covers Golden Gate Strait connecting the Pacific Ocean to the San Francisco Bay. The red colour of the bridge is from the red rust free paint used to save the bridge from the ravages of weather. It is also a favourite spot to commit suicides. People come from far and near to keep their appointment with death. Besides patrolling, numerous suicide hotlines and posters try to discourage the people from jumping off the bridge and into the frigid waters of the strait, a drop of about 75m.

World’s tallest buildings reach completion simultaneously with onset of major recession
The year 2008 will long be remembered as the start of an economic crisis that has gripped the entire globe – a year that may also have brought to an abrupt end the worldwide construction boom of the past decade that has seen ever-denser cities containing ever-taller buildings proposed from Madrid to the Middle East, from Shanghai to San Francisco. As financial shock waves have reverberated around the world, high-profile tall building projects in virtually all skyscraper cities have been cancelled, delayed, or put on hold in response to the precarious global economic conditions. The question that everyone is now asking – is this the end of the tall ambitions of places such as Moscow, Chicago or Dubai for the short-mid term future?
The correlation between tall buildings and economic recession is not a new one. In 1999 the economist Andrew Lawrence created the ‘Skyscraper Index’ showing how almost all of the world’s tallest buildings throughout history have reached completion virtually simultaneously with the onset of a major economic recession. Using the research and criteria of the Council on Tall Buildings and Urban Habitat (CTBUH), and specifically their annual ’Ten Tallest Buildings Completed Annually’ and projected ‘Tallest 20 in 2020’ research, this paper seeks to examine further the link between skyscrapers and economic cycles, and suggest how the current economic crisis will affect tall building developments in the next decade or so.

FREEBURGH Bridge is finally open again, 14 months after being closed due to safety concerns.
Works were completed on Monday and the bridge officially reopened today.
The $263,100 project saw the old 15-tonne capacity structure completely replaced.
Although still single lane the new bridge has no load limit and includes a shared path.
Alpine Shire Council assets director Charlie Bird said the project had been delivered without delay.
“I think we talked about it being delivered in April this year so it has been delivered on time which is great,” he said.


Weston Package gets green light
The Government announced today that a bid for extra money to improve transport in Weston-super-Mare will go ahead.
Called ‘Weston Package’ the investment will see £11 million added to £4 million already pledged which will fund some significant transport improvement schemes for both car and motorcycle drivers, bus passengers, cyclists and pedestrians.
The Weston Package includes:
- Increased capacity at Junction 21
- New bus link from Queens Way to the station
- Bus priority along Elmham Way for buses, linking the regeneration areas
- Widening Marchfields Way to complete the dual carriage-way into the town and provide new bus and cycle routes
- New car park and bus interchange at Worle railway station
The next phase of Weston Package involves detailed design and procurement. Construction is programmed to start in autumn 2012. Residents and businesses will be kept informed as the stages progress.
The go ahead for Weston Package is in addition to the schemes announced last week by the Chancellor in his autumn statement. These included the go ahead for the South Bristol Link and the Ashton Vale to Temple Meads scheme, both of which will benefit North Somerset residents and commuters. The bids have been strengthened by cross-council working between the four West of England councils (Bath & North East Somerset, Bristol, North Somerset and South Gloucestershire) and could deliver a total of £250 million investment in local public transport boosting the local economy.

Infrastructure: Romanians take to the skies
29 October 2009
"The only people who do not grumble about the lack of trains and motorways in Romania are pilots," remarks Gândul. Air travel is taking off in the 238,000 km2 country, which has only 3 motorways and no high-speed train lines. In 2008, "9.1 million people passed through the nation's 17 airports, generating more than 600 million euros in revenue," reports the Bucharest daily. "Better road and rail infrastructure would have resulted in a less significant development of the air sector," says Catlin Radu, the Ministry of Transport's Director of Civil Aviation, who is clearly enthusiastic about the trend. "The six or seven years we will need to complete the construction of ground infrastructure represent a real opportunity for airports."
