Hydrological Study of an Urban Region within the Indravati River Basin

The hydrology of an area reflects how precipitation contributes to runoff, evapotranspiration (ET), percolation, and other processes, collectively known as the water budget or water balance. Understanding urban hydrology requires a thorough analysis of these components to promote sustainable development. This study estimates rainfall distribution as part of evaluating the urban water balance, using water balance modeling through the Soil and Water Assessment Tool (SWAT) for an urban region within the Indravati River basin. The Indravati River basin is divided into 15 sub-watersheds, with the highest population density observed in the 14th sub-basin. In analyzing the water balance across these sub-watersheds, results show that the 14th sub-watershed has the highest surface runoff, measured at 586.32 mm, while the 12th sub-watershed has the lowest surface runoff at 309.33 mm. Additional parameters, including percolation and ET, are also assessed in this study. The findings provide valuable insights into urban hydrology and water management within the Indravati River basin.
