Erosion control is the practice of preventing or controlling wind or water erosion in agriculture, land development, coastal areas, river banks and construction. Effective erosion controls handle surface runoff and are important techniques in preventing water pollution , soil loss , wildlife habitat loss and human property loss.
The water is then either filtered (sand or cartridge filter,) or settled (lamella clarifier or weir tank) prior to discharge. Chemical sediment control is currently used on some construction sites around the United States and Europe, typically larger sites where there is a high potential for damage to nearby streams. [3]
A tetrapod is a form of wave-dissipating concrete block used to prevent erosion caused by weather and longshore drift, primarily to enforce coastal structures such as seawalls and breakwaters. Tetrapods are made of concrete , and use a tetrahedral shape to dissipate the force of incoming waves by allowing water to flow around rather than ...
A water bar in the Catskills. The trail forks right; the drainage ditch to the left. A water bar or interceptor dyke is a road or trail construction feature that is used to prevent erosion on sloping roads, cleared paths through woodland (for utility companies such as electricity pylons), or other accessways by reducing flow length. It is a ...
Surface runoff (also known as overland flow or terrestrial runoff) is the unconfined flow of water over the ground surface, in contrast to channel runoff (or stream flow). It occurs when excess rainwater , stormwater , meltwater , or other sources, can no longer sufficiently rapidly infiltrate in the soil .
New ways to deal with water are constantly being developed and tested, such as the underground storage of water, storing water in reservoirs in large parking garages or on playgrounds. [90] Rotterdam started a project to construct a floating housing development of 120 acres (0.49 km 2 ) to deal with rising sea levels. [ 91 ]
A solution proposed by Enbridge to prevent further erosion in the Bad River along Line 5 is still awaiting approval from the Bad River Band as winter approaches.
Natural bio-logs/fiber logs can be used to reduce bank erosion and stabilize inclines by implementation at the bottom of a slope or in the water which is formed to the bank line and secured in place. The coconut fiber and netting are biodegradable and work to grab sediment, hold moisture to facilitate vegetative growth, and allow stability of ...
