rill and sheet erosion

syn. sheet erosion 

More or less uniform removal of soil from an area by rain-drop splash and overland flow without the development of water channels exceeding 30 cm in depth. Included with sheet erosion, however, are the numerous but conspicuous small rills that are caused by minor concentrations of runoff.
