Types Of Water Erosion
It is scattering of detached soil particles by the impact of rain drops.
The velocity of rain drop may be 30 kmhr.
It is uniform removal of soil in thin layer like a sheet from gently sloppy land resulting from overland flow occuring in thin layers.
the beating of raindrops combined with surface flow of rain cause the initial microscopic rilling.
Rill erosion is removal of soil by water from small well defined channels when there is a concentrationof overland flow
the erosion having channels larger than rills and which can not be removed by tillage operation is called gully erosion.
Gully erosion is advanced stage of rill erosion.
