Abstract

Watershed management includes site appropriateness evaluations for rainwater gathering structures. It requires a substantial amount of data from numerous disciplinary sources. For mapping natural resources and creating the requisite spatial databases needed as input for GIS analysis, remote sensing is incredibly useful. GIS is the perfect instrument for gathering, storing, and analyzing spatial and non-spatial data, as well as for creating models based on existing components to provide appropriate natural resources development and management action plans. The best method for choosing good locations for rainwater harvesting structures is to use both of these strategies in tandem. In the current research, anIn the selected study region, which is located in the Solani watershed of Dehradun District, Uttarakhand, India, integrated remote sensing and GIS-based technique is utilized to determine the suitable sites for rain water harvesting structures. For the purpose of collecting thematic information about the area, such as geomorphology, geological structures, soil, landuse landcover, well sites, drainage pattern, etc., IRS-1D P6 - LISS III & IV precision geocoded FCC data on 1:50,000 scale and field observation data were employed. In order to create the slope map and flow accumulation maps, Survey of India toposheets at a scale of 1:50,000 were used. the numerous

The integration of theme layers and field observation data into the GIS enabled a variety of spatial and non-spatial queries. The ideal locations for installing water harvesting and artificial recharge structures were found.
Key words: farm pond, check dam, DEM, stream order, barren terrain, watershed, rain water harvesting, remote sensing, and GIS.
