Résumé
The Murray River is one of Australia’s longest rivers but in South Australia it has become degraded through river regulation, water extraction and adjacent highland irrigation. These have decreased the natural flood frequency and increased rates of floodplain salinization. Concerns have been raised about the quality of water extracted from the Murray River for industrial, agricultural and potable uses, including for metropolitan Adelaide’s water supply. This has been highlighted as the most significant hydrological risk by the Murray Darling Basin Authority (MDBA) and therefore a comprehensive understanding of flow and solute dynamics within the river and floodplain environment is essential. Hence, this research is aimed at developing a better understanding of surface water (SW) and groundwater (GW) flow and solute interactions in a semi-arid river-floodplain system using a numerical modelling approach.
