Abstract

The 761.2 acres of the Yarehalli micro-watershed in the Channagiri taluk of the Davanagere district served as the study's site. In 2017 the rainfall recorded was 931.8 mm of total rainfall, of which kharif rainfall made up 60.2%, rabi rainfall 20.1%, and summer rainfall 19.6%. This study's goal is to pinpoint the site-specific interventions that should be made in accordance with the Integrated Mission for Sustainable Development (IMSD) principles. The sites are located by superimposing thematic maps of slope, runoff potential, soil permeability, and stream order created with ArcGIS. The findings indicate that 57.31% of the overall area is suitable for check dam construction, compared to 23.17% for agricultural ponds, 8.57% for percolation ponds, and 1.12% for gully plugs. Locations for the water harvesting constructions that collect water in the structures are indicated.
