  7. 7. Name of Study Major Findings Specific Yield Study for Planning and Designing AR Structures in Sub-urban in Chennai The artificial recharge structure suitable for the region is the percolation pond with injection wells. Injection wells can be constructed inside the tanks to a depth of 13 to 20 mbgl. The top of the injection well should be kept at the flood point level of the tanks. Study of Ground Water Dynamics and Installation of Real Time Ground Water Monitoring System in NCT, Delhi Under the study it was proposed to install automatic Data Logger on Piezometer at selected locations. But the procurement of data logger could not be materialized due to certain reasons beyond control. However, the study has been completed using manual measurement
