The Importance of Structural Risk Mitigating Measures for Coastal Cities
Abstract
Risk Mitigating methods – protecting community, protecting commerce.
46 tropical cyclones have hit Australia since 1967 causing damage estimated at AS$ 8.8bn. The perception of coastal risk in Australia appears to be relatively low, although there is growing awareness of the link between development and ‘disasters’ as the assets at risk increase2.
This paper looks at emergency management issues related to increased development and the importance of protecting people and assets. Although the means of protection are generally different for both, a developed area is likely to need a combination of emergency responses and structural protection.
The paper identifies various types of structural solutions against coastal hazards and examines positive and negative aspects of each. General issues relating to coastal structures are also discussed.
The implications of climate change on coastal hazards in Australia are summarised. The paper then examines government guidance on climate change in relation to coastal structures in Australia.
The paper concludes by examining risk management options available, including lessons learned from past floods. The paper finds that structural solutions are an integral part of risk management for developed areas, along with planning, predicting and warning of events.
