Sediment control Wikipedia

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 sediment controls.

Fine Fraction Analysis (Silt plus Clay) At the end of 20 seconds, insert the pipette to a depth of 20 cm and withdraw the precise subsample (exactly 20 ml). Inasmuch as the subsequent analysis is based on this subsample, this is the most important single step. If excess liquid is accidently drawn into the pipette,...
