From the rainfall records of the Meteorological Observatory at the Tamil Nadu Agricultural University for the years 1938 to 1983, the kinetic energy of the storms was calculated using the method suggested by Wischmeier (1959). From the kinetic energy and the intensity of rainfall, the erosion index for each month and annual erosion index values were worked out. Monthuise and seasonwise erosion index values were analysed and conclusions were drawn based on the erosion index values of Coimbatore region in India.
