Brief description Rivers are the main source of freshwater for many ecosystems in semi-arid zones. River water may seep into the floodplain aquifer, providing an accessible store of low-salinity water within freshwater lenses. The project will investigate lens dynamics using numerical groundwater models supported by extensive field data from the lower River Murray, where freshwater lenses are declining. We will model lens extent, growth and decline in response to natural variations in climate and to changes in landuse, river regulation and groundwater pumping. Project results will evaluate management options to promote freshwater lenses, with the aim of improving river salinity and floodplain vegetation health.
