Sommaire partiel
Sasive Halla Basin was chosen for the study as groundwater is the only source for agricultural development of the area. The area forms a part of black soil plains of northern Karnataka and covers an area of 653 sq. kms. in the north eastern part of Dharwad district. A remote sensing based integrated approach has been made to understand the groundwater domain in the area. The concept of Hydrogeomorphological evaluation has been adopted in the study. Various land forms and significant hydrogeomophic features such as fractures/lineaments have been identified and delineated with the help of multidate, multiband satellite imagery and aerial photographs. Each of the land forms have been evaluated for its groundwater potential and the hydrogeologic function of fractures/lineaments have been evaluated by detailed geological, electrical resistivity, hydrogeological and other field investigations. A few test drillings have also been taken up. Groundwater quality for drinking as well as irrigation has been established and areas prone for hazards have been identified. Stable and radioactive isotopic analysis has been carried out to understand the origin and salinisation of groundwater. Climatological aspects of the area and their influence on groundwater resources have been studied. Present land use/land cover, cropping pattern, extent, pattern and effect of irrigation has been studied. Groundwater draft for irrigation has been computed by the acreage estimation of croplands with the help of remote sensing techniques. Groundwater recharge, withdrawal and balance have been computed. A sustainable scheme for development and management of groundwater has been evolved.
