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.

Seawater intrusion

This resource introduces the concept of seawater intrusion, which is a natural process, but one that can be exacerbated by human activitiy. Seawater intrusion can cause salty seawater to contaminate coastal or inland bores, rendering them unusable. This factsheet also describes some of the research that NCGRT scientists are doing in this area.

Using chemistry to measure river bank storage

This publication introduces a new method for investigating whether, during floods, river water is pushed into the river bank, and if so, how far it travels into the adjacent aquifer. This has important implications for water management.
