Abstract

Climate change and increases in population density in coastal areas might increase the difficulty of coastal management decision-making. Although recent research has proposed several flood risk assessment methods in response to climate change, few approaches have addressed all significant effects. Therefore, this study aims to establish a thorough method to evaluate the risks of future coastal flooding events, including all climate change effects. The study proposes an advanced risk analysis scheme that covers all annual flood events during a target term. To confirm the effectiveness of the proposed model, this study applies the model to actual risk analysis in the North Somerset coast in the UK under 10 different cases.

The flowchart is divided into four main parts: 1) setting up calculation conditions, 2) hazard modelling, 3) executing inundation calculations, and 4) vulnerability analysis
