Applied geomorphic mapping for land management in the River Murray corridor, SE Australia

The River Murray Corridor, in SE Australia, was the subject of a large integrated project aimed at providing answers to a number of important land and environmental management questions and guidance for land use planning. Airborne electromagnetic (AEM) surveys were carried out in conjunction with a light detection and ranging survey in 2007. These data were combined with various satellite remote-sensing data and field observations to produce a number of maps, including maps of landforms and surface materials. These latter maps were used to assess the value of the AEM data, identify potential surface and sub-surface flow pathways and map potential recharge on the Murray River floodplain surface. This allowed the assessment of potential salt storage and the impact of various land use options on salt storage and mobilisation.
