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.
A sediment control is a practice or device designed to keep eroded soil on a construction site, so that it does not wash off and cause water pollution to a nearby stream, river, lake, or sea. Sediment controls are usually employed together with erosion controls , which are designed to prevent or minimize erosion and thus reduce the need for ...
Silt fence installed on a construction site. Silt fences are often installed as perimeter controls. They are typically used in combination with sediment basins and sediment traps, as well as with erosion controls, which are designed to retain sediment in place where soil is being disturbed by construction processes (i.e., land grading and other earthworks).
They are also used when construction delays and weather conditions prevent timely installation of other erosion control practices. [10] This is typically seen during the construction process of large-scale permanent dams or erosion control. As such, check dams serve as temporary grade-control mechanisms along waterways until resolute ...
The Universal Soil Loss Equation (USLE) is a widely used mathematical model that describes soil erosion processes. [1]Erosion models play critical roles in soil and water resource conservation and nonpoint source pollution assessments, including: sediment load assessment and inventory, conservation planning and design for sediment control, and for the advancement of scientific understanding.
Construction site runoff controls (i.e. erosion and sediment controls) Post-construction (i.e. permanent) stormwater management controls; Pollution prevention (e.g. improved chemical handling, including management of motor fuels and oil, fertilizers, pesticides and roadway deicers) and "good housekeeping" measures (e.g. system maintenance).
Examples from erosion include: Koge Bay (Dk), Western Scheldt estuary (Nl), Chatelaillon (Fr) and Ebro delta (Sp). [6] There is an obvious downside to this strategy. Coastal erosion is already widespread, and there are many coasts where exceptional high tides or storm surges result in encroachment on the shore, impinging on human activity.
Rolled erosion control products are blankets or netting created with both natural and synthetic materials used to protect the surface of the ground from erosive forces and promote the growth of vegetation. RECPs are often used in locations highly susceptible to erosion, such as steep slopes, channels, and areas where natural vegetation is sparse.
