Climate Projection of Extreme Sea Level Events Along the Queensland Coast

Lawrence, Rachael (2017) Climate Projection of Extreme Sea Level Events Along the Queensland Coast. [USQ Project]


Much of the Queensland coastline has frequently been exposed to and affected by tropical cyclones. From November to April, Australia endures its annual cyclone season. Rising sea levels in this region have been found to be well above the globally averaged sea-level rise, therefore information about extreme sea levels associated with severe tropical cyclones due to rising sea levels is sought after by coastal management and planning agencies now and into the future.

The number of tropical cyclones as well as tropical cyclone intensity over the past 20 years will be examined, in an environment of increasing sea-level. About 20 years of sea-level data from tide gauges around the Queensland coast will be used. This study investigates the possible impact of the climate change (e.g., sea level rise) on the frequency and intensity of tropical cyclones in the study area.

From the results, it was found that a decline in tropical cyclone landfall numbers seasonally, however other findings within this analysis has shown that whilst here is a general decline in cyclone occurrences, fewer lower category cyclones are occurring where the incidence of higher intensity, more severe cyclones are more prominently occurring over time.

Tropical cyclone storm surge is both directly and indirectly dangerous to all stakeholders in the coastal environment. Tropical cyclones and the associated surge effects have the potential to bring destructive winds, coastal inundation, erosion, damage to infrastructure, loss of life and damage the biological environment which exists particularly in low lying areas. Governing agencies/bodies and organisations must take precaution in careful preparation through appropriate planning, policy-making and through initiating effective response now and more importantly into the future.
