The surface runoff was assessed for Kohima and Dimapur districts of Nagaland from rainfall events for 18 years (from 2003 to 2020) using USDA Soil Conservation Service-Curve Number (SCS-CN) method. This study generated the hydrologic soil group (HSG) and land use land cover (LULC) maps using the GIS tools. The weighted curve number (CN) values were determined based on the Antecedent Moisture Condition (AMC-2), integrating the HSG and LULC classes. The highest runoff and rainfall were found in July, with 206.1 mm and 307.6 mm values, respectively. This indicates that maximum runoff is generated during the kharif (June to September), resulting from higher rainfall. The study shows that, without reliable hydrological data, the SCS-CN model can be utilized to estimate surface runoff depth
