The University of Sydney in conjunction with DHI Water & Environment, The NSW Department of Natural Resources, Port Stephens Council, Great Lakes Council and the Jimmy’s Beach Restoration Society Inc has been awarded an ARC linkage Grant by the Australian Government.
The aim of this project is to determine the interrelated morphodynamics of flood tide deltas and adjacent estuarine beaches. These relationships will be investigated using DHI numerical models for a range of different hydrodynamic and morphological scenarios. Long term changes such as system’s response to climate change and associated rises in sea level will be evaluated with the numerical models, following validation of field data collected during this study. The ability to model this complex morphodynamic system will result in an improved understanding of numerous similar systems on wave-dominated coastlines throughout the world.
To achieve this aim, the project will:
- Determine the location and direction and rates of sediment transport;
- Measure the waves and tidal currents that drive the transport;
- Apply this information to model the delta and shoreline so that a number of test solutions to mitigate the problem can be tested; and
- Apply the models to predict the impact of climate change: rising sea levels, increasing tidal prisms and a changing wave climate.
The MIKE 21 FM (flexible mesh) series will be applied for this study, which will include MIKE 21 SW (spectral wave), HD (flow model) and ST (sediment transport).
