Taking a Systems Approach to Estuary Management

The NSW Estuary Management Program involves local communities in the management process via nominated representatives on estuary management committees. The vast range of issues involved in estuary management can be a challenge to these committees. Community representatives often enter the process focussing on a particular management issue that concerns the group they represent (e.g., a fishing ...

Modelling the effect of marine processes on deltaic wetlands

Deltaic wetlands are among the most biodiverse systems on earth, provide important ecosystem services, and are natural buffers against violent storms and hurricanes. Marine processes change the planar configuration and internal stratigraphy of deltaic wetlands, and understanding their contribution to wetlands development and deterioration processes is a key issue for society. In this thesis, fi...

Multi-scale simulation of fluvio-deltaic and shallow marine stratigraphy

We present a parameterization of fluvio-deltaic drainage network evolution and alluvial architecture in a basin-scale 2-DH model. The model setup is capable of producing convergent and divergent channel networks. Major elements are the alluvial-ridge aggradation and the coupled overbank deposition, the dimension and style of the channel belt and the sub-grid stratigraphic expression. Avulsions ...

Models of Deltaic and Inner Continental Shelf Landform Evolution

The morphology of passive continental shelves is dictated by the input of sediments from rivers and their redistribution by waves, currents, and gravity-driven flows. The pathways followed by sediments sculpt a landscape whose diversity is rarely matched on Earth’s surface. Sediments are released to the shelf from triangularly shaped, elongated, and dendritic deltas. Barrier islands rise from g...
