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.
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 ...
Check dams still require maintenance and sediment removal practices. They become more difficult to implement on steep slopes, as velocity is higher and the distance between dams must be shortened. [5] Check dams, depending on the material used, can have a limited life span but if implemented correctly can be considered permanent. [5]

Sediment basin installed on a construction site. A sediment basin is a temporary pond built on a construction site to capture eroded or disturbed soil that is washed off during rain storms, and protect the water quality of a nearby stream, river, lake, or bay.
Hydrodynamic scour is the removal of sediment such as silt, sand and gravel from around the base of obstructions to the flow in the sea, rivers and canals. Scour, caused by fast flowing water, can carve out scour holes, compromising the integrity of a structure.
Silt may occur as a soil (often mixed with sand or clay) or as sediment mixed in suspension with water. Silt usually has a floury feel when dry, and lacks plasticity when wet. Silt can also be felt by the tongue as granular when placed on the front teeth (even when mixed with clay particles). Silt is a common material, making up 45% of average ...
A desander with a 10 inches (250 mm) cone is able to remove 50% of solids within the 40-50μm range at a flow rate of 500 US gallons per minute (32 L/s), while a desilter with a 4 inches (100 mm) cone is able to remove 50% of solids within the 15-20μm range at a flow rate of 60 US gallons per minute (3.8 L/s).
