• 1. Both qualitative and quantitative action of rainfall must be considered as the effects of rainfall on soil erosion, and the writer adopted the total rainfall amount for quantity of rainfall and the maximum rainfall amount per 1 hour for quality of rainfall. 2. The multiple correlation coefficient R_<PIm・E> is highly significant and high, and the formula E=aP+bI_m+c is derived, where E=soil erosion P=total amount of a rainfall I_m=maximum rainfall amount per 1 hour a, b, c=constant 3. Surface run-off R is same as soil erosion, and the formula R=aP+b'I_m+c'is derived, where R=surface run-off a, b', c'=constant 4. If other conditions are same, the effect of ground cover is expressed by the values of b/a and b'/a', and these values are small in case of good ground cover like forest.
