GIS BASED APPROACH FOR ASSESSING THE SURFACE RUNOFF HARVESTING POTENTIAL : A CASE STUDY

Abstract

One of the finest practices for mitigating the problem of water scarcity is the installation of a rainwater collection system.  It also has the greatest effect on the completion of irrigation projects and groundwater recharge. Simply, we may define it as the surface area of the ground or the rooftop area of a building by calculating the rooftop area and water loss estimate for the specific region. The current case study examines how a geographic information system might be used to assess the possibilities for rainwater harvesting in the campus of Pune University. By taking into account the Pune University's boundaries, the polygon function is used in QGIS to determine the rooftop and road surface areas of the several buildings in the Pune University campus. It makes it possible to determine the potential for rainwater on roadways and rooftops. By the implementation of the proposed GIS based system, we will be able to determine the appropriate kind of water collecting structure and the quantity of structures needed thanks to the current investigation. Water conservation in the study region is a very good and efficient way to deal with the water shortage.
