Method & Evidence

AimTo develop and apply a methodology for assessing coastal flood risk under sea level rise and extreme sea level scenarios, considering various contributing factors and their uncertainties.
MethodIntegrated modelling and spatial analysis
ProcedureThe study regionalized sea level projections, incorporated thermal expansion, dynamic changes, freshwater addition, glacial isostatic adjustment, and vertical land movements. Extreme storm surges and waves were projected, and their joint probabilities analyzed. These combined sea level projections were then superimposed onto a high-resolution digital elevation model to generate flood hazard maps for different timeframes and climate scenarios.
