Estimation of Erosion Index from Daily Rainfall Amount

ABSTRACT A method was developed for estimating the erosion in-dex for rainfall events from daily rainfall amount. The relationship that was used includes both a deter-ministic component and a random component. Data from 22 locations in the eastern one-half of the United States were used to evaluate the relationship. The parameters of the relationship were found to vary both with location and with season at a location. The pro-cedure was used to estimate erosion index from daily rainfall data for two locations.
