Abstract The quantitative analysis of morphometric parameters is found to be of immense unity in river basin evaluation watershed prioritization for soil and water conservation and natural resource management at watershed level. The influence of drainage morphometry is very significant in understanding the landform processes, soil, and erosional characteristics. An attempt is made to study the significance of morphometry, integrating Remote Sensing data and techniques in addition to the conventional methods in a GIS platform. The study has demonstrated the potential use of remotely sensed data and Geographical Information Systems (GIS) in evaluation of linear, relief and areal morphometric parameters and to analyze their influence on the genesis and processes of landforms and characteristics of soil parameters like texture, drainage and land erosion conditions. GIS is an effective tool to analyze spatial and non-spatial data on drainage, geology, landforms and soil parameters to understand their inter-relationships. Geo-coded resource database generated on drainage, landforms in the core of GIS provides an excellent means of storing, retrieving and analyzing data at river basin level to find out their association. It also provides a powerful mechanism not only to upgrade and monitor morphometric parameters but also to permit the spatial analysis of other associated resources database. An attempt has been made to utilize the interpretation capabilities of GIS to find out the relationships between the morphometric parameters at sub basin level.
