ØYes: Sediment yield from terrace channels and simple sediment control basins

ØNo: Ephemeral or permanent incised gully erosion

ØNo: Stream channel erosion

ØNo: Mass wasting


	RUSLE2 estimates sediment yield and sediment characteristics from overland slopes, low grade terrace type channels, and small sediment basins.
	RUSLE2 sediment yield estimates are not estimates of sediment yield from fields unless the slope length ends at the edge of field.
	Remember: RUSLE2 is designed to capture main effects.
	RUSLE2 should be used to design sediment basins or channels.
	RUSLE2 does not estimate ephemeral gully erosion. While ephemeral gully erosion within field sized areas is a critical element in conservation planning, the benefits of controlling ephemeral gully erosion are not explicitly considered in RUSLE2.
	Also, runoff management and disposal from field-sized areas is critically important. RUSLE2 is not designed to determine all of the benefits of runoff management in a field-sized area, even though it is a critically important part of conservation planning.
