Forest Service WEPP Documentation

	Cross Drain Predict sediment yield from a road segment across a buffer. CrossDrain can be used to determine optimum cross drain spacing for existing or planned roads, and for developing and supporting recommendations concerning road construction, reconstruction, realignment, closure, obliteration, or mitigation efforts based on sediment yield.	Rock:Clime Create and download a WEPP climate file to your PC. The Rocky Mountain Climate Generator creates a daily weather file using the ARS CLIGEN weather generator. The file is intended to be used with the WEPP Windows and GeoWEPP interfaces, but also can be a source of weather data for any application. It creates up to 200 years of weather from a database of over 2600 weather stations and the PRISM 2.5-mile grid of precipitation data.
	WEPP:Road Predict erosion from insloped or outsloped forest roads. WEPP:Road allows users to easily describe numerous road erosion conditions.	WEPP:Road Batch Predict erosion from multiple insloped or outsloped forest roads
	Disturbed WEPP Predict erosion from rangeland, forestland, and forest skid trails. Disturbed WEPP allows users to easily describe numerous disturbed forest and rangeland erosion conditions. The interface presents the probability of a given level of erosion occurring the year following a disturbance.	ERMiT ERMiT predicts the probability associated with a given amount of soil erosion in each of five years following wildfire. ERMiT allows users to predict erosion following variable burns on forest, rangeland, and chaparral conditions.
	WEPP FuME (Fuel Management) The FuME interface predicts soil erosion associated with fuel management practices including prescribed fire, thinning, and a road network, and compares that prediction with erosion from wildfire.
