In the current study, an attempt has been made to determine morphological parameters of Tidi Watershed falling in Udaipur district of Rajasthan, India. Remote Sensing and GIS technique has proved to be an efficient tool in drainage network delineation and their updation in morphological analysis. For detailed study, ASTER DEM has been used for delineation of watershed boundary and geographical information system (GIS) was used in evaluation of basic, linear, areal and relief aspects of morphometric parameters. The Tidi watershed is sprawled over an area occupies of 114.36 km2 with a dendritic drainage pattern. The study area is designated as fifth order basin and lower and middle order streams mostly dominate the basin with the drainage density value of 1.74 km/km2 which exhibits gentle to moderate slope terrain and medium dense vegetation. The mean bifurcation value of the watershed is 3.88 and the value varies from 2 to 4.14 which shows that drainage network formed on homogeneous rocks when the influences of geologic structures on the stream network is negligible. Elongation ratio of 0.79 infers the watershed to be closer to a less elongated. The results from the morphometric analysis of the watershed are very beneficial for developing and designing conservation structures of soil and water and watershed management measures.
