• Erosion and sedimentation - Department of Water

    13/11/2018  Erosion is the transport by wind, water and ice of soil, sediment and rock fragments produced by the weathering of geological features. Sedimentation occurs when eroded material that is being transported by water, settles out of the water column onto the surface, as the water flow slows.

    Erosion is a process of geological denudation, which involves the breakdown and transport of rock materials. Two other kinds of denudation often work ahead of erosion: weathering, the fragmenting of rock by physical, chemical and biological means; and mass wasting, wherein gravity begins pulling the rubble of weathering from its source.
