Remote Sensing and GIS Based Comparative study of watershed of different Physiographic Conditions, Wainganga Sub Basin, Maharashtra

Abstract

The present study carried by a Wainganga river basin is of critical importance for Maharashtra to preserve its watershed, drainage, relief, soil, forests, wildlife, and tribal population dependent on it. Protecting the basin however does not seem to be priority for the state. The very lifeline of the Wainganga River is being subjected to growing pressure. Its flow has already been obstructed at several places with dams and barrages. By 2012 there were as many as 149 dams built in Wainganga basin. The river in its initial reaches flow westwards and thereafter southwards in M.P. State and continues to flow Southwards in Maharashtra State. Several studies related to different aspects of channel cross section and longitudinal profile river have been carried out from different parts of the country and abroad. Recent emphasis is placed on quantitative geomorphology of drainage basin by various methods and measures to establish the interrelationship of cross section and longitudinal profile river and to impact on river morphology. Water is not only for sustains of life but also determines the quality of life. Assessing water quality is important as quantity in water resources planning and management. It may be observed that the existence of human being a lot of serious problem to disturbance of quality and quantity of water. There are several reasons for scarcity of water and most important things to the increasing population and changing environment condition in the local as well as world level. For sustainable development requirement to that fresh water is indispensable for human survival. Water is being transferred to irrigation and urban industrial uses, putting additional stress on the performance of the irrigation sector. Keeping in mind the scarcity of water resources to cater to the multi various needs of the growing population along the Wainganga River with the vagaries of monsoon precipitation and dearth for quality of water. The purpose of the present research work is to describe the physical condition in Wainganga drainage basin as a system unit resulting from the interaction between landuse & landcover and topography, which is an impact of socio economic condition and surrounding area or region.
