What Causes Sheet Erosion

Cause and dynamics of sheet erosion. Sheet erosion is caused by the force of raindrops impacting on bare soil (Ellison 1944) and dislodging particles of earth. This force is dependent on the speed of fall (a function of the length of fall and the wind-speed) and the weight (a function of the diameter of drops).

What causes sheet and rill erosion?

Sheet and rill erosion Sheet erosion occurs when a thin layer of topsoil is removed over a whole hillside paddock—and may not be readily noticed. Rill erosion occurs when runoff water forms small channels as it concentrates down a slope. … If they become any deeper than 0.3m they are referred to as gully erosion.
