Karratha Coastal Vulnerability Study

A study of the impacts of future climate change, the hydrology around Karratha, shoreline stability, flooding from storm surge and riverine flooding. From storm surge and hydraulic modelling, a set of maps have been produced for the 2. 10, 100, 200 and 500 year ARI events for the 2010, 2060 and 2110 climate scenarios. These maps show flood extent, depth and levels from combined effect of storm surge and riverine flooding taking into account joint probability.
