Estimation of Groundwater Potential in Indian Arid Environment Using Isopach Mapping Technique: A Case Study

摘要

An approach for estimating groundwater potential in Luni block of Jodhpur district by isopach maps that were prepared based on electrical resistivity method are highlighted in this paper. Groundwater potential and quality of different aquifers are estimated based on the depth to bed rock, thickness of saturated zone and aquifer resistivity drop ratio. The total groundwater potential of suitable quality is estimated to be around 49 mcm. The isopch maps prepared based on electrical resistivity survey to estimate the thickness of saturated zone are found fairly compatible with the ground conditions.
