Erosion and Sedimentation — Hydropower Sustainability Tools

Hydropower projects are likely to cause changes to the pre-existing erosion and sedimentation patterns in the affected river system. There is considerable knowledge and experience globally of the mitigation measures that can be employed to avoid, minimise and mitigate erosion and sediment related impacts from hydropower developments.Erosion and Sedimentation - river, important, types,,State and federal laws provide some consideration of erosion and sedimentation control along streams and lakes during flood control, drainage, highway, bridge, and other stream-related construction projects. A variety of programs administered by public and private agencies encompass research projects, education programs, technical assistance, regulatoryErosion - Wikipedia,In earth science, erosion is the action of surface processes (such as water flow or wind) that removes soil, rock, or dissolved material from one location on the Earth's crust, and then transports it to another location (not to be confused with weatheringwhich involves no movement). This natural process is caused by the dynamic activity of erosive agents, that is, water, ice (glaciers), snow, air (wind), plants, animals, and humans. In accordance with these agents, erosion is som…

While the tectonic effects on surface processes such as erosion have long been recognized (for example, river formation as a result of tectonic uplift), the opposite (erosional effects on tectonic activity) has only recently been addressed. The primary questions surrounding this topic are what types,Water pollution: erosion and sedimentation - Canada.ca,The sediment cycle starts with the process of erosion, whereby particles or fragments are weathered from rock material.

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.

Sedimentation is an important parameter to assess the life of a reservoir. Seventy-eight years ago, Cook was the first to identify mathematically, the three major factors affecting soil erosion in the catchment of a reservoir. As sedimentation is dependent on sediment yield and sediment yield depends on soil erosion, it is required to predict all three parameters to estimate the life of a,,,
