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.
River erosion in the UK. River bank failure can be caused when the gravitational forces acting on a bank exceed the forces which hold the sediment together. Failure depends on sediment type, layering, and moisture content. [1] All river banks experience erosion, but failure is dependent on the location and the rate at which erosion is occurring ...
Tillage erosion is the soil movement and erosion by tilling a given plot of land. [3] A similar practice is contour bunding where stones are placed around the contours of slopes. Contour plowing has been proven to reduce fertilizer loss, power, time consumption, and wear on machines, as well as to increase crop yields and reduce soil erosion.
This in turn decreases fuel use, pollution and the carbon footprint significantly, while at the same time lowering the construction environmental footprint in terms of less dust, erosion and runoff. When used for slope applications, perforated CCS provides excellent soil protection, water drainage and growth stratum for plants for the ...
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 ...
Vegetation and slope stability are interrelated by the ability of the plant life growing on slopes to both promote and hinder the stability of the slope. The relationship is a complex combination of the type of soil , the rainfall regime , the plant species present, the slope aspect , and the steepness of the slope.
Silt fence installed up-slope of a vegetated stream buffer. A silt fence, sometimes (misleadingly) called a filter fence, [1] is a temporary sediment control device used on construction sites to protect water quality in nearby streams, rivers, lakes and seas from sediment (loose soil) in stormwater runoff.
Asphalt and sandbag revetment with a geotextile filter. A revetment in stream restoration, river engineering or coastal engineering is a facing of impact-resistant material (such as stone, concrete, sandbags, or wooden piles) applied to a bank or wall in order to absorb the energy of incoming water and protect it from erosion.
