The present study used SCS curve number method to estimate the runoff of Kudavale micro watershed in Dapoli Tehsil (Ratnagiri). It was necessary to quantify the land use land cover (LULC), hydrologic soil group (HSG), antecedent moisture condition (AMC) and curve number (CN) of the study area to estimate runoff and to design different soil and water conservation structures. Thus, land use land cover map and hydrologic soil group map are extracted in ArcGIS. Land use land cover map of study area was estimated in ArcGIS software using Landsat 8 satellite imagery collected from USGS earth explorer. For computing HSG map, textural analysis of soil samples collected from study area was done by Bouyoucous hydrometer method. The study found that the area under agricultural land, forest land, barren land and residential area was 15.42 %, 59.90 %, 21.22 % and 3.4 %, respectively. It was also observed that the value of curve number for AMC I, II and III was 58.31, 69.68 and 84.36, respectively. The hydrologic soil group of the study area showed that Group A, Group C and Group D types of soil was present in the watershed. The rainfall data of 30 years (1990-2019) was analysed to estimate runoff of watershed. The average runoff of watershed was found to be 1532.27 mm i.e. 41.15% of total rainfall.
