摘要：The study intents to determine the surface runoff using Soil Conservation Service-Curve Number(SCS-CN) method. For the watershed management and understanding hydrological characteristics, the SCS-CN method is extensively used. The effective indicators like land use/land cover, soil texture, rainfall has been selected for the present study. The CN method is an index that help to estimate the runoff depth at different hydrological soil groups combining LULC and soil texture. To estimate the surface runoff, the selected parameters have been integrated with the help of ArcGIS software. The results show that the value of annual surface runoff varies from 677.07mm to 1348.12 mm within this river basin. It has found that in the middle catchment area amount of runoff is lower than the upper and lower catchment in pre-monsoon season and reverse condition is found in post-monsoon. The average annual runoff of this basin is relatively higher than the other parts due to having the high slope and elevation.
