Technical Abstract: As part of a broader effort to provide more information on hydrologic and water quality models, this paper presents an overview and evaluation of the Revised Universal Soil Loss Equation (RUSLE). It briefly discusses the background of RUSLE as it evolved from the USLE, and the basic changes involved in the revision. The validation of RUSLE is discussed, though limited data restrict the analysis for all except the standard cropping and management situations. The evaluation examines the new situations to which RUSLE can be applied, including those requiring estimates of sediment delivery and representing significantly different land uses. The changes in RUSLE make it useful for estimating erosion and sediment yield not only from agronomic settings, but also for situations involving construction, mine spoils, and land reclamation. The analysis then examines the strengths and weaknesses of the current RUSLE layout and computer interface and the changes being included in the new RUSLE2 program. Finally, the overview includes a listing of sources for the program and supporting documentation.
