Forest and the water are naturally interwoven as forested watersheds have altogether been diverse conduct from non-forested watersheds as the previous is more useful in the penetration, precipitation of rainfall. The idea of the vegetation in the catchment zone is significant in ground water revive also overflow and soil dampness conditions, soil disintegration and soil quality (Biao et al. 2010; Bruijnzeel 2004). Notwithstanding the way that the water and forest relationship isn't too shortsighted, being a result of numerous elements of climatic, topographical and organic nature, the significance of forest in water protection has been acknowledged all around (Bradshaw et al. 2007; Makarieva et al. 2006). Topography along these lines assume a fundamental job in the circulation and event of ground water .In South India, the enormous Late Archaean Closepet batholith gives a surprising chance to examine the emplacement of granitic magmas at various crustal levels, thus crops out along a characteristic crustal segment traversing 10–13 km inside and out, from granulitic lower covering in the South to greenschist-facies high class in the North. Because of its stretch shape, the principle body of the Closepet batholith has been recommended to be syntectonically emplaced during strike-slip tectonics by Drury et al.

The Dodahalla watershed of Chikmagalur area of Karnataka information were collected from the Karnataka State Remote Sensing and by Karnataka State Natural Disaster Management Center Bangalore application focus. Making distinctive topical guides of lithological highlights in the chose region utilizing Remote Sensing and GIS Techniques. Bend ARC GIS variant 10.2.2 helpful instrument to producing distinctive Lithological maps zones of Karnataka. Utilized 1:50,000 scale toposheet for referenced reason.

Where progressive Land Use Land Cover spread information from 1991 to 2018 propose that lithology has assumed an indispensable job in water stockpiling underneath the surface where we can see increment in development of cropland, 45 to 57 % of area , Agriculture 12 to 27 % of area ,Forest development kept up 5 to 6 % of region where as Scrub Land which likewise kept up 1 to 5 % of territory . The principle observatory factor is that Water Bodies kept up 2 % of region during that time which hold the way that fairly vacillation in precipitation, humidity, temperature lithology helped in keeping up water bodies consistent.

In view of the writing overview and visual translation of satellite information combined with geographical field work, lithounits have been recognized and portrayed, Migmatites and Granodiorite - Tonalitic Gneiss spread the significant part fallowed by Basal Polymict Conglomerate, Ultra Mafic Schist complex, Granite (Shimoga), Quartz Chlorite Schist with Orthoquartzite, Ultra Mafic Schist. The overall pattern of the developments is NNW to SSW (Dharwarian pattern) and dipping NW and NE heading (From 15° to 80°), these arrangements structure some portion of Chitradurga schist belt.
