Spaceborne Estimation of Groundwater Variability in Northwestern India

The project is estimating quantitative and qualitative deterioration  of the groundwater depletion in northwest India. As a case study we took Kanti village in Haryana and acquired field data through geophysical surveys like Electrical resistivity tomography (ERT) and Ground Penetrating Radar (GPR). We have also done public awareness campaign at panchayat and school levels about the issues they might face in future if they continue similar practices.  Multi-mission space observations and Global hydrological model outputs are used to separate groundwater from total water storage and then it is validated by insitu observations provided by the Central Ground Water Board (CGWB). The study also analyses shrinking aquifers and their possible resilience in the Kanti village. Towards the end of the study policy recommendations for the extraction/irrigation policy to produce will be given along with the identification of suitable solutions like recharge zones.

Proposed Future Work Details

As an extension to this work, we will evaluate land subsidence caused by overexploitation of groundwater. With this theme NISAR proposal result awaited .
