“…Excessive rainfall can make the river flood and inundate the catchment causing damage and erosion (Khazaei et al 2012;Simin et al 2012;Ozturk et al 2013). Hence it is primarily important to model the rainfall-runoff relation of the area to channel out the excess water before flooding (Rao et al 2010;Alfa et al 2011). SWAT is a physically-based runoff model capable of discretising large watersheds where simulation at ground scale is difficult to execute (Fadil et al 2011;Arnold et al 2012;Shi et al 2013).…”

The present study aims to propose an integrated watershed development plan for the Wainganga basin situated in Maharashtra, India. Also, the study involves evaluating the performance and applicability of SWAT (Soil and water assessment tool) as a runoff model along with the trend analysis of rainfall for the above mentioned study area. The decadal land-use/land-cover (LULC) variation from 1985 to 2005 has been studied using data procured from Goddard Earth Sciences Data and Information Services Center (GES-DISC) and groundwater table level of the study area was monitored using dug/bore well data collected from Central Ground Water Board (CGWB). Rainfall trend analysis for a period of 101 years using historic rainfall data procured from the India Meteorological Department (IMD) has been analyzed to foresee the future scenario. It was observed that the rainfall-runoff relationship of the area is getting affected by the LULC variation and thereby affecting the groundwater regime. There is a significant deterioration in the forest cover and water bodies which is alarming. The study devises the importance of an immediate master plan to be implemented in the basin to avoid any future crisis. Also, the study emphasizes the advancement of remote sensing in the use of hydrologic models like SWAT more realistically.
