Abstract:
Rainfall-runoff modelling provides an useful input to the water resources planning and management. The Soil Conservation Service Curve Number (SCS-CN) method (SCS1956) is the most widely used method world over. Mishra and Singh (1998 a) presented a modified version of the SCS-CN method. In this report, the modified version is applied to the storm rainfall-runoff data of 14 watersheds from an arid region and 2 from sub-humid regions of India, and the results are compared with those of the existing version. The modified version is found to perform better than the existing SCS-CN method in all applications to the data of 16 watersheds.
