Abstract: 
The current study intends to prepare the surface runoff and ground-water prospects for the Rainwater Harvesting Structure. One of the most important resources in our daily lives, water is running out more quickly in both rural and urban regions due to rising home and agricultural demand. Groundwater is becoming more and more important in water resource planning because there is a shortage of high-quality subsurface water and a growing demand for water for industrial, agricultural, and residential use. The monsoon's persistent failure, rising demand, and overuse cause the groundwater table to fall. To some extent, this issue could be resolved by artificially replenishing the potential aquifers. Consequently, the current study uses an integrated approach of remote sensing and GIS Weighted Overlay to evaluate the Rainwater Harvesting Structure in Chilapura watershed Honnali Taluk, Dhavangere District, based on surface runoff and ground water possibilities. utilizing remote sensing and auxiliary data in a GIS platform, this study was conducted utilizing a variety of thematic maps covering drainage, slope, soil, geomorphology, lithology, land use, and land cover isohyet. According to the outcome, there are enough areas for percolation tanks, storage tanks, dam ponds, and exploration dams. Water in the dry area will be saved since the generated map will assist in choosing the best site for water harvesting facilities.An additional benefit over traditional research is the use of remote sensing and GIS analysis of spatial suitability to detect rainwater harvesting facilities. In the research area, appropriate heights for the test dam constructions and storage/percolation tank stop tank are provided.
