Almost 80% of the major aquifers of the world are parts of sedimentary basins. Basin-scale to regional-scale groundwater flow in these aquifers determines the nature of groundwater resource available in these areas. The groundwater flows along gradients of gravity or other geodynamic forces (e.g. tectonism, isostatic rebound etc.) and hydrogeochemically evolve along the flowpath. In our group, we evaluate the nature of these flows through delineated aquifer systems along with associated chemical changes. We apply a range of qualitative and quantitative techniques including field investigation, numerical simulations of flow, analytical calculations, thermodynamic modeling and multivariate statistics.
