GEO-HYDROLOGICAL CONDITION OF THE UPPER CATCHMENT AREA OF THE KUMARI RIVER BASIN USING GEO-SPATIAL TECHNIQUES

The study was conducted in the upper catchment area of the Kumari river basin. Geo-hydrology elaborates the mode of occurrence of subsurface water and helps to identify the suitable sites for recharge of groundwater. The main aim of the study was to identify the geo-hydrological condition of the upper catchment area of the Kumari river basin. The integrated geospatial techniques had been formed to be very efficient tools for the appraisal of geo-hydrological aspects of the area of study. Survey of India (SOI) topographic maps, IRS P6 satellite image (LISS IV MX), ASTER DEM (Provided by Ministry of Economy, Trade and Industry of Japan & National Aeronautics and Space Administration), georeferenced Geological map, well inventory and ground truth data were used to prepare various thematic maps such as slope, DEM, drainage order and density, lineament density, land use/ land cover, hydro-geomorphologic, groundwater depth in identifying the present geo-hydrological condition. The study revealed that the integration of all attributes made known to us the present geo-hydrological condition. And after the discussion, it was revealed that the area suffered from poor geo-hydrologic situation
