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 silt fence on a construction site.. Geotextiles and related products have many applications and currently support many civil engineering applications including roads, airfields, railroads, embankments, retaining structures, reservoirs, canals, dams, bank protection, coastal engineering and construction site silt fences or to form a geotextile tube.
On construction sites they are often implemented in conjunction with sediment controls such as sediment basins and silt fences. Bank erosion is a natural process: without it, rivers would not meander and change course. However, land management patterns that change the hydrograph and/or vegetation cover can act to increase or decrease channel ...
A silt fence, a type of sediment control, installed on a construction site. EPA has authorized 47 states to issue NPDES permits. [25] In addition to implementing the NPDES requirements, many states and local governments have enacted their own stormwater management laws and ordinances, and some have published stormwater treatment design manuals.

Many modern land drains are created utilising rigid or flexible plastic pipes pierced with holes, laid in pea gravel. (The pea gravel is pea-sized pebbles without sharp points to damage the pipe.) Geotextile material can surround the gravel to keep out silt. This can be installed in an excavated trench.
