Prevent Erosion and Control Soil Sediment Movement with Turf You are here: KB Home Environmental Benefit Prevent Erosion and Control Soil Sediment Movement with Turf < BackSoil exposure following earthworks is recognised as a major contributor to soil losses and sediment entering waterways. In urban areas, construction activity is a major cause of unwanted soil movement. Sediment in waterways is strongly linked to increased levels of nutrients such as nitrogen and phosphorus, which are responsible for algal blooms. Developers are required to abide by regulations limiting the movement of sediment from a site. There are a number of techniques deployed to control sedimentation and erosion; yet how best to stabilise a slope and reduce movement of sediment remain vexed issues.
