Abstract: Rainwater harvesting is a crucial strategy for augmenting water supply, especially in regions facing water scarcity. This study focuses on the Bilaspur region of Chhattisgarh, India, where rapid urbanization and agricultural expansion have increased water demand. The objective of this research is to assess the rainwater harvesting potential using the Soil and Water Assessment Tool (SWAT), a widely used hydrological model.
The study area was delineated into hydrological response units (HRUs) based on land use, soil properties, and topography. Meteorological data such as precipitation, temperature, and relative humidity were obtained from local weather stations and incorporated into the model. Calibration and validation of the SWAT model were performed using observed streamflow data, and the model performance was evaluated through statistical metrics such as Nash-Sutcliffe Efficiency (NSE) and coefficient of determination (R²), demonstrating satisfactory results.
The study identified key areas suitable for rainwater harvesting, highlighting the spatial distribution of surface runoff and groundwater recharge potential. Results suggest that implementing rainwater harvesting systems in specific zones can significantly reduce water shortages and improve groundwater levels. The estimated volume of rainwater that can be harvested provides a basis for policy recommendations on sustainable water management in Bilaspur.
This research contributes to a better understanding of the hydrological processes in semi-arid regions and offers insights for water resource planners to integrate rainwater harvesting as a viable solution. The SWAT model proved to be a valuable tool for assessing rainwater harvesting potential in the region.
