Aalysis of Governing Concepts Water Erosion, Sediment Yield and Transportation Processes in the Watersheds
Author(s):
Abstract:
Sediments are defined as loose particles of sand, clay, silt and other substances which are transported by water and finally deposited at the downstream of the watersheds water bodies. Sediments cover a wide range of diameters of transported particles. However, fine suspended sediments have been considered well due to their signifact relationship with transport of nutrients, tracers, heavy metals and other pollutants through river systems. Accordingly, undrestanding dominant processes of suspended sediment transportation in a watershed and authentic perception from the important related concepts such as sediment mobilization, sediment remobilization, sediment yield, sediment storage, sediment deposition, sediment redistribution, sediment budget and sediment cascades lead to handle problems of sediment associated pollutions and sediment management programmes. To this end, the present article tried to achieve the same appropriate undrestanding of aforesaid concepts and their processes importance and recall the importanc of holistic simulation of watersheds behavior in context of sediment management.
