Developing better predictions for extreme water levels and waves around Australia

This project will improve predictions of extreme water levels arising from: tides, storm surges, surface gravity waves, continental shelf waves and meteorological tsunamis around Australia. The project will increase the accuracy of extreme water level predictions in selected regions of Australia by the inclusion of physical processes not previously considered.  Research will apply hydrodynamic models (ROMS, SELFE) of the Australian continental shelf region to determine annual maximum water levels that will be used to estimate exceedance probabilities around the coastline.  Multi-year hindcasts of the wave climate will be undertaken using SWAN and Wind Wave Model (WWMII).  Coupled model runs between SELFE and WWMII will also be performed to investigate the effects of waves on the hydrodynamics.
