| Abstract: | The present paper focuses mainly on the assessment of groundwater availability in the Upper Agniar and Vellar basins. The remote sensing data was used to map the geomorphological units and structural pattern. The integration of geomorphology and structural pattern with geophysical and well inventory data reveals that shallow groundwater occurrence is controlled by geomorphological characteristics whereas at intermediate depth faults/fractures control the yield of groundwater. The study has also indicated that the eastern part of the basins is more favourable for groundwater development than the western part. |
