Abstract: Satellite based remote sensing techniques and GIS have demonstrated their efficacy in quantitative and qualitative assessment of drainage basin. The drainage system's quantitative analysis is a crucial component of watershed characterization. Morphometry deals with mathematical quantifying of various aspects of basin. The present study focuses on the morphometric analysis of Kanchi River watershed using remote sensing and GIS approach for optimal management and planning of the basin's groundwater resources. The Kanchi River is one of the major tributaries of Subarnarekha River in eastern India. In this study SRTM (date of acquisition- 2nd January 2015)) is used to extract the crucial hydrological parameters of Kanchi River in ARC GIS 10v. For microlevel morphometric analysis the study area has been divided into 21sub watershed based on 4th stream order and above. The linear, aerial and relief parameters have been calculated and their hydrological inferences were discussed. The drainage area of Kanchi watershed is 1023.68 sq km and the main stream of the basin is of 6th order with dendritic to sub- dendritic and parallel drainage pattern. Most of the morphometric parameters such as bifurcation ratio, drainage density, drainage texture, stream frequency, form factor, basin relief conclude that the basin is elongated in nature with high overland flow due to some structural control. The database generated by the study can provide scientific information for site selection of water recharge structures in the basin.
