Recent research indicates that worldwide climate change is likely, leading to changes of the mean sea level and the wind climate. The paper presents a methodology to find the most effective strategy for coastal flood protection in a changing climate. The method is based on risk-based optimisation of the flood defence design. Scenarios for climate change, including associated uncertainties, are included.

Key words: flood defence systems, risk-based design, optimisation, climate change
