Question

What is reservoir sedimentation?

Answer 1

Reservoir sedimentation is erosion or we can say deposition of sediment carried  into reservoirs formed and contained by dams and this is not safety to dams and also reduces the energy production from water i.e hydroelectricity and by the way it also affects the flood attenuation capabilities.

Answer 2

Explanation:

Sedimentation is the tendency for particles in suspension to settle out of the fluid in which they are entrained and come to rest against a barrier. This is due to their motion through the fluid in response to the forces acting on them: these forces can be due to gravity, centrifugal acceleration, or electromagnetism.
