Abstract :

Over Morphometric analysis has been carried out to determine the drainage basins characteristics of the river. In the present study the Bori, Ajani, Bhokad & Mor which are tributaries of the Tapi river are used for morphometric analysis by using Remote sensing and Geographic Information System (GIS) techniques. An evaluation of morphometric characteristics of a drainage basin requires preparation of drainage map, length of drainage channels, ordering of various streams and measurements of catchment area and the then drainage density, bifurcation ratio, drainage frequency which help to understand the nature of drainage basin. On the basis of study of these watersheds, Drainage density of upper and lower has been detect the change from 2.15 to 1.82 and 1.85 to 1.62 respectively. In the present study update the drainages using LISS IV (5.8 mt. Resolution) image and calculate morphometry. GIS (Geographical information system) & RS (Remote sensing) have been proved to be efficient tools in drainage delineation and updation.
