Extreme water levels

Potential impacts and hazards of extreme water level events along our coasts are increasing as populations continue to escalate and the mean sea levels rise.

To better prepare, coastal engineers and managers need accurate estimates of exceedance probabilities for extreme water levels.  Coastal regions experience the rise and fall of sea levels, which vary at timescales of hours, days, weeks, months, annually and so on, governed by the astronomical tides, meteorological conditions, seismic events, local bathymetry and a host of other factors.  The group is undertaking a project to develop better predictions and forecasts for extreme water levels around Australia arising from storm surges, surface waves, continental shelf waves, tsunamis and the mean sea level rise.
