Erosion is the wearing down of a landscape over time.It includes the detachment,transport,and deposition of soil particles by the erosive forces of raindrops and surface flow of water.
A land area contains rills and channels.Raindrop impact can detach soil particles on unprotected land surfaces between rills and initiate transport of these particles to the rills.From the small rills,the particles move to larger rills,then into ephemeral channels and then into continuously flowing rivers.Entrainment and deposition of particles can occur at any point along the path.When erosion occurs without human influence,it is called geologic erosion.Accelerated erosion occurs when human activity increases the rate of erosion.
Erosion is a matter of concern to watershed and natural resource managers.Two of the main reasons reservoirs are built are water supply and flood control.Erosion upstream of a reservoir deposits sediment in the bottom of the reservoir which lowers the reservoir
