TYPES OF EROSION

ØEphemeral gully

ØPermanent, incised (classical) gully

ØStream channel

ØMass movement

ØGeologic


	RUSLE2 estimates interrill and rill erosion, sometimes referred to as sheet-rill erosion. Other procedures must be used to estimate the other types of erosion.

	Ephemeral gullies reoccur in the same location, rills are parallel and generally do not reoccur in the same location.
