ABSTRACT
Erosion is a natural process to detach soil and rock fragments for subsequent removal, or transportation, of these materials to areas of lower elevation on the surface of the earth. In the context of agriculture, the primary agents for erosion are water and wind. Climate, precipitation in particular, plays a critical role in determining where and when erosion occurs and the magnitude of erosion rate. Rainfall erosivity, i.e., the ability of rain to cause erosion, is largely a function of rain amount and peak intensity. Rainfall erosivity and its seasonal variation in relation to the Universal Soil Loss Equation (USLE) and the revised USLE (RUSLE) can be estimated from mean annual rainfall and daily rain amount. Low rainfall, dry soil surface, and poor ground cover are the necessary conditions for wind erosion to prevail.
