Accurate estimation of runoff and sediment yield amount is not only an important task in physiographic but also important for proper watershed management (Gajbhiye et al. 2014a; Gajbhiye 2015). Watershed is an ideal unit for planning and management of land and water resources (Gajbhiye et al. 2013; Gajbhiye et al. 2014d). Direct runoff in a catchment depends on soil type, land cover and rainfall. Of the many methods available for estimating runoff from rainfall, the curve number method (SCS-CN) is the most popular. The curve number depends upon soil and land use characteristics. This study was carried out in Kanhaiya nala watershed located in Satna district of Madhya Pradesh using remote sensing and GIS. The total area of watershed 19.53 km2. Soil map, Land Use and slope map were generated in GIS Environment. Since the curve number method is used here as a distributed model, it is necessary to get information concerning a large number of sub-catchments in the basin. Hence remote sensing and GIS techniques have been used. Landsat (ETM) satellite image was used to obtain land cover information by ERDAS 9.1 software. The thematic layers like soil map, elevation map, rainfall map and land cover map were created in Arc GIS 9.3. Curve numbers are assigned for different land cover and soil types. In present study the runoff varies from 1196.93 mm to 1551.17 mm of the study area.
