ABSTRACT

The morphometric analysis of the river basin is a quantitative and mathematical analysis of the landforms. It playsa vital role in understanding the geology and the hydrogeological characteristics of a drainage basin in relation to morphological feature and their pattern. The watershed is stretched between latitude 17⁰ 05’24’’N to 17⁰ 01’48’’N and longitude 74⁰ 05’24’’E to 74⁰ 19’48’’ E in Survey of India Toposheet number 47 L/4 on scale 1:50000 located in Sangli district of the Maharashtra state in India. The present basin can address the morphometric of morphometric parameters such as stream order, stream length, bifurcation ratio, drainage density, stream frequency, texture ratio, elongation ratio, circularity ratio, and form factor ratio.
