      The erosion process by overland flow was analyzed in its fundamental aspects. A general predictive erosion equation was developed by combining the conditions for conservation of mass of the sediment, boundary hydraulic shear, and the sediment transport formula of Einstein-Brown. The ability of the equation to predict sediment yield from overland flow areas was demonstrated using field data from rainfall simulator plots. Comparison of the results indicated that the erosion equation presented herein can be used to predict sediment yield from unrilled overland flow areas with satisfactory confidence.
