Morphometric Study of Area Drainage Basin on Pravara Drainage Basin using Geospatial techniques

Abstract Basin morphometry is a method or a measurement of various attributes of a basin in a form of a number. The morphometric analysis is quite common in observing how a watershed drains, to assist in the river basin development and management schemes. The morphometric parameters have the ability to examine linear, areal and relief. In this research we selected Pravara basin since it is a highly relief ratio basin and in terms of area occupies 3474.4 square kilometers. The current work paper primarily examines parameters that are contained in the areal morphometrics which are basin area, drainage density, frequency of streams, texture ratio, elongation ratio, circularity ratio and the form factor ratio. Morphometric analysis on GIS is used in this study. The current study is quite helpful in planning and managing a drainage basin. The areal morphometric parameters are significant in the aggregate decisions in flood management, soil erosion determination and water resource management in the localized scale.
