Morphometric Analysis of Indrayani River Basin using Remote Sensing and GIS Techniques and Priortization of Watershed Tushar D. Bangar1, Dhirajkumar P. Wagh2, Shubham B. Wahurwagh3 Dr. Budhajirao Mulik College of Agricultural Engineering and Technology, Mandki-Palvan, Chiplun, Maharashtra, India. --------------------------------------------------------------------------***----------------------------------------------------------------------Abstract: Geographical information system (GIS) and Remote sensing has become an efficient tool in delineation of drainage pattern and water resource management. GIS and image processing techniques can be employed for the identification of morphological features and analyzing properties of basin. The morphometric parameters of basin can address linear, areal and relief aspects. The present study deals mainly with the geometry, more emphasis being placed on the evaluation of morphometric parameters such as stream order(Nu), stream length(Lu), bifurcation ratio(Rb), drainage density(Dd), stream frequency (Fs), texture ratio (T), elongation ratio (Re), circularity ratio (Rc) and form factor ratio (Rf) etc.. study area is Indrayani River, geographically located between 18°57’ to 18°35’ N latitudes and 73°25’ to 74°0’ E longitudes located in Pune district of Maharashtra state of India. The GIS based morphometric analysis revealed the 7th order drainage basin and drainage pattern mainly. The total numbers of streams of whole river basin area is 14842 in which 9611 are first order, 4539 are second order, 541 are third order, 122 are fourth order, 25 are fifth order, 3 are sixth order and 1 are seventh order streams. The length of stream segment is maximum for first order stream and decreases as the stream order increases. This study would help the local people for the management of the soil and water conservation practices and created structures of CCT, SCT, Terreces and Bunds for the reduces the soil erosion and recharge the ground water potential. Keywords: Remote sensing, GIS, Morphometric analysis, Watershed Prioritization, INTRODUCTION Remote sensing and GIS techniques are the proven efficient tools in the delineation, updating and morphometric analysis of drainage basin. The drainage basin analysis is important in available water resources. Geomorphometry is the measurement and mathematical analysis of the earth’s surface and its dimensions of the landforms (Clarke, 1996). The properties gives important information related with the formation and development of hydrologic and geographic properties of watershed. This analysis gives the quantitative description of drainage, which is an important aspect of the basins (Stahler, 1964). The areal parameters shows the shape, geometrical and topological parameters like stream frequency, Drainage density. Morphometry is depends upon the topology of basin or watershed. The information related with the geomorphology, hydrology, geology, and land use pattern is highly important for doing trusted study of drainage pattern of the watershed. In recent decades the morphometric analysis of the various River Basins have been done by many researchers and scientist (Esper,2008; Gaikwad and Bhagat,20017; Akash pandule,2019;) have studied morphometric parameters for watershed and prioritization. In this study to understand various characteristics of Indrayani river basin which helps to understand the topographic relation, agriculture and regional planning. Also understanding of a river basin depends on careful study both the physical and human characteristics of that basin. Land and water resources are limited and their wide utilization is imperative, especially for countries like India, where the population pressure is increasingly continuous. These resource development programmes are applied generally on watershed basis and thus prioritization is essential for proper planning and management of natural resources for sustainable development. Watershed deterioration is a common phenomenon in most parts of the world due to mismanagement of natural resources and faulty agricultural practices as well as social development activities. Morphometric analysis could be used for prioritization of micro-watersheds by studying different linear, aerial and relief parameters of the watershed. The watershed © 2022, IRJET
