Models of soil erosion by water historically have been primarily either empirically-based or process-based (sometime referred to as physically-based). The first models of soil erosion were empirically-based. The prime example of the empirically-based model is the Universal Soil Loss Equation (USLE). More recent models have been based on equations that describe the physical, biological, and/or chemical processes that cause or affect soil erosion. It is important to understand that both the process-based and the empirically-based model possess a major empirical component, in the sense that the constitutive equations use parameters based on experimental data. This chapter details some of the important elements of soil erosion models and factors that influence their use.
