Summary
A key challenge for the management of alluvial aquifers in the Murray–Darling Basin (MDB) is to properly quantify surface water–groundwater exchanges. In particular, the contribution of losing-disconnected rivers to alluvial aquifer recharge is poorly understood. The water table in losing-disconnected rivers is well below the streambed, which is sometimes interpreted as meaning that no exchange is taking place. This is not correct because infiltration will still occur through the unsaturated zone below the rivers. The aim of this collaborative project was to re-evaluate the conceptual representation of losing rivers and to develop practical guidelines and methodologies to apply this knowledge for the management of alluvial aquifers.
