Runoff Map Preparation for Khadakwasla using Arc-CN Runoff Tool

Abstract

Khadakwasla watershed was investigated to generate the runoff maps using the Arc CN runoff tool which is an extension of the ArcGIS with the help of remote sensing and geographical information system. Attempt was made to understand the basaltic terrain in spatial context to find out runoff from Landsat Thematic Mapper imagery and other collateral data. Subsequently, these layers were processed to derive runoff from Soil Conservation Service Curve Number (SCS-CN) method using Arc-CN runoff tool. In conclusion, the method used in present study deciphers the more precise, accurate and ability to process large catchment area to generate the runoff maps.
