Groundwater movement in heterogeneous aquifers
The NCGRT’s team at the University of New South Wales studies the movement of water through aquitards – relatively impermeable underground layers such as clay. Normally, water is expected to flow horizontally through porous substances such as sand, and be limited in its movement downward by aquitards. One new project is showing that substantial amounts of water can, in some cases, move through heterogeneous clayey systems in response to pumping.
