Groundwater dynamics and surface water interactions in the Lower Murrumbidgee Catchment New South Wales

The aim of this project is to advance our understanding of groundwater flow and quality in the Lower Murrumbidgee catchment of NSW. Groundwater and surface water will be sampled across the catchment, and in selected bores before, during and after irrigation seasons. A combination of element and isotope chemistry, in particular uranium and strontium isotopes, will be used to track groundwater recharge, fluxes, age and natural and human impacts on groundwater and surface water flow and water quality. A geochemical toolbox will be developed for assessing anthropogenic impacts on groundwater, and the long-term sustainability of groundwater resources.
