CSIRO will apply its cutting-edge 3D extreme events simulation flood modelling research to coastal areas of Queensland to assess the impact of growing sea level rises.

Researcher Mahesh Prakash says although the 3D simulation is only in the trial phase in China, it will reach Australian shores in October.

He says CSIRO has just been granted approval to apply the dam modelling techniques to areas of coastal Queensland to address rising concerns over the impacts of sea level rises and storm surges.

Dr Prakash says this type of modelling is the first of its kind on such a large scale.

“It can potentially identify if the structure of a building will still be liveable following a flood and shows how the structure will be affected, if it’s still stable – and if it is, identifies if people can refurbish those buildings or if it has to be torn down,” he told insuranceNEWS.com.au.

Modelling for coastal regions comes as CSIRO discusses options to bring the modelling to Australia for the wider application of flood mitigation.

Dr Prakash believes this kind of technique will outstrip current flood-mapping data, as it can provide much more detail such as how building structures and important infrastructure will be affected.

The research project follows concerns raised over insurance gaps in coastal regions with predictions of sea level rises reaching 1.1 metres by 2100, costing an estimated $226 billion in damage.

Dr Prakash says various types of scenario modelling will be used to look at the impacts of rising sea level rises and storm surges, but CSIRO has to use “a degree of sensitivity” to eliminate residents’ fears over the future of their homes.

“We will say what would happen if this region is affected by sea level rises and will be careful not to alarm people,” he said.

Dr Prakash says this research will enable governments and councils to determine areas that are appropriate for future development.
