King Saud University, Saudi Arabia


            Rainfall erosivity index of the Universal Soil Loss Equation was obtained, using the daily rainfall records for twenty station, covering most of the regions in the Kingdom of Saudi Arabia. The kinetic energy and the erosivity index (EI30) were estimated by Wischmeier's Equation. composite curves were drawn as a basis for determining the erosive power of rainfall. A risk of erosion from rainfall exists in some areas of the Kingdom. Also, a contour map of the erosion factor (R), was produced to form as a basis for planning and designing appropriate soil conservation practices throughout.
