Alluvial gully erosion has been one of the dominant contemporary sediment sources in many of the large rivers draining into the Gulf of Carpentaria, yet, fundamental questions persist concerning the phenomenon both in terms of causal mechanisms and extent. In this project a baseline assessment of alluvial gully erosion in four tropical savannah rivers was undertaken resulting in both the development of a gully erosion conceptual model and an assessment of the spatial extent of gully erosion.

The results have highlighted the significance of gully erosion as a source of sediment into the Gulf of Carpentaria. The maps also show distinct patterns in the distribution of the gullies, which provide a basis for explaining some of the underlying processes driving gullying in this landscape.
