Abstract: One of the popular methods for computing the depth of surface runoff for a given rainfall event is the Soil Conservation Service Curve Number (SCS-CN) method. Research conducted on the applicability of the SCS-CN method suggested a need for improvement. Consequently, several modifications of the method have been suggested and reported in literature. The important modified versions of the method include Mishra and Singh (MS) model, Michel et al. model, Sahu et al. model and SME model. These modified models have been reported to perform better than the original method for U.S. watersheds. In the present study, these modified models are applied to two Indian watersheds in Maharashtra and are compared with each other for their performance. The results indicated that the SME and the Sahu et al. model perform equally well compared to each other, and the duo perform consistently better than the original SCS-type method and the others for both the Amba and Kalu watersheds. Further, the performance of the MS model is found to be better than the Michel et al. model.
