 · 4.7.1 Temporary Sediment (Silt) Traps Definition A temporary sediment or silt trap is formed by excavation or by constructing a small embankment of stone, stone-filled bags, or other material to retain sediment. Sediment traps are considered temporary structures and often placed at the site on an as needed basis by field personnel.

 · Sediment, including soils, mud, clay, silt and sand, is the single main pollutant generated at construction sites and largely arises from the erosion of exposed soils by surface water runoff. Good surface water management during construction is essential in preventing sediment pollution and minimising risk of prosecution, with the potential for ...

 · a silt trap assuming that the particles are spherical. In order for a silt trap to serve its purpose and to maintain a high efficiency, the particles should fall below the outlet level before reaching the opposite of side of the trap. The smaller the particle size, the less it will weigh and therefore have a smaller downward force exerted.

 · sand, silt, and clay may be tested in the lab. Once tested, the textural class of the soil can be determined by referring to the textural triangle. Soils with different amounts of sand, silt, and clay are given different names. For instance, a soil containing 40 percent sand, 40 percent silt, and 20 percent clay is called loam soil.

 · Silt, sand, clay, and gravel all mix to form soil. Silt is also determined by the naked eye and touch by its slippery, non-sticky feel when wet, as opposed to clay, sand, or gravel. It has a flour-like consistency when dry. Silt is found more in semi-dry environments than anywhere else. 3. Role in Agriculture
