Sustainable water resource planning and management of any of the watershed is essential. This may be achieved by Geomorphometric alalysis using GIS and remote sensing. In this paper the study of Thorli Watershed from Ratnagiri District of Maharashtra state is presented. Sustainable development and management of the Thorli Watershed is influenced by topography of the area and the geomorphologic features. Geomorphometry supplies quantitative drainage network analysis and geomorphic evolution of the Thorli basin have been carried out. The various aspects of Geomorphometric parameters such as Drainage Density, Slope, Shape of the Basin, Bifurcation ratio, Length ratio and landuse & landcover map along with geological parameters gives the precise and objective overview about the watershed.  This is the seasonal rain fed watershed, hence needs better management. Sustainable developments and management of the watershed is influenced by topography of the area and the geomorphologic features. Geomorphometry supplies the quantitative values to geomorphology and hydrology.

The remote sensing (RS) and Geographical Information System (GIS) has been adopted for geomorphometric analysis of the study area. The software ILWIS (developed by ITC, Netherlands) has been used for inputting managing, analyzing, interpreting and presenting the data. The generated geoinfromatics can be readily used for decision-making. The attempt has been made to study some geomorphometric parameters of Thorli basin. The manual estimation of geomorphic parameters is tedious and cumbersome process. However, through this attempt, it has been found that integration of RS & GIS allows reliable, accurate and most updated data base tool for handling spatial data, very useful in deriving geomorphometric parameters which are essential for planning future infrastructural, sustainable water resources planning of the study area.
