Universal Soil Loss Equation (USLE)

The universal soil loss equation (usle) is one of the most widely used empirical models for estimating long-term average soil loss. Wischmeier and Smith introduced this equation in 1978; the U.S. Soil Conservation Service first utilized USLE on a large scale. Soil erosion has for a long time been a major concern, particularly because of its negative impacts on agriculture and sedimentation of reservoirs. A range of natural and anthropogenic factors influence soil erosion processes, which occur in all landscape types and under a range of land use systems. USLE was intended for cropping systems, but is also applicable to nonagricultural conditions (such as construction sites). USLE was developed to predict annual soil loss rates from a particular field or single slope, where it is ...
