What is it about?

Usually, crystalline hard-rocks are less permeable rocks with sparse fracture-networks, which poses the challenges for aquifer imaging. We simulated these fractures using electrical signals to understand the subsurface connectivity within an experimental hydrogeological park with managed aquifer condition. A decadal-scale time-lapse resistivity variation also recognized the influence of such conditions along-with shallow water-levels throughout the year for park and neighbouring areas, despite having highly heterogeneous rocks. The three-dimensional model provided an overview of shallow and deep flow-paths establishing the aquifer system hydraulic connectivity.

Why is it important?

Our findings indicate that artificial recharge tank strengthens the recharge dynamics of the hard-rock aquifer system, which gives a substantial rise in the water-levels for the experimental park and the adjacent regions.
