Fractal properties of Australia's river catchment boundaries

The fractality of catchment boundaries for surface waters means that, near the boundaries, the flow dynamics exhibits sensitive dependence on initial conditions and a high degree of uncertainty. What are the consequences of this fine-scale boundary structure for predicting flood risk and management of water resources? In this project we propose to characterize the fractal properties of key parts of the Lake Eyre, Gulf of Carpentaria, and/or Murray-Darling river catchment boundaries with the aim of reducing final state uncertainty and improving predictability.

Since the outcomes of this project will help to inform long-term policy on Australia's water resources, highly diplomatic engagement of diverse stakeholders and end users will be necessary (not surprisingly).
