Rainfall erosivity of the Revised Universal Soil Loss Equation (RUSLE) is influenced by the type, amount, and intensity of storm. In this research, rainfall data from 18 recording rain gauge stations were collected and analyzed. Further, their single storm, daily, monthly, and annual erosion indices were calculated and estimated by different models. Duration of each rainfall was divided into 15 min intervals. Intensity and energy of each interval, maximum rainfall intensity of 30 min, total energy of each rainfall, and erosivity index of every single storm were calculated. Furthermore, Cooley's model for single storm was evaluated and its coefficients were …

The rainfall erosivity index is one of the most important factors influencing soil erosion. For this reason, investigating the accuracy of rainfall erosivity indices is very important in different climatic regions. The objective of this research was to investigate different rainfall erosivity factors and determine the most appropriate ones for use in the central and northeastern parts of Iran. For this reason, necessary data were collected from 92, 6 and 10 soil erosion research plots in Khorasan Razavi, Semnan and Isfahan provinces, respectively. The rainfall intensities were recorded, as was the sediment yield associated with storm events, and 63 different …
