Pilot Aquifer Mapping

The project was implemented in six select areas in different hydrogeological environs of the country as depicted. The area includes the following parts of country.

A summary of the pilot areas have been tabulated as follows :- Aquifer Mapping in Pilot area

On the basis of integration of data generated from various studies of hydrogeology & geophysics, aquifers have been delineated and characterized in terms of quality and potential. Various maps have been prepared bringing out Characterization of Aquifers, which can be termed as Aquifer maps providing spatial variation (lateral & vertical) in reference aquifer extremities, quality, water level, potential and vulnerability (quality & quantity).

On the basisof aquifer characterization, issues pertaining to sustainable aquifer management in the area have been identified. Initially, a conceptual model has been developed for the pilot area and subsequently, a mathematical model has been formulated simulating the field situation, which was calibrated and validated with the field data. Various scenarios have been tested in the model to study the response of the aquifer to various stress conditions and predictive simulations have been carried out up to the year 2025. Aquifer response Model has been utilized to identify a suitable strategy for sustainable development of the aquifer in the area.
