摘要：
Floods are the most common natural disasters worldwide, which can cause serious damage to property and fatality, especially in urban areas. Hence, flood risk management is essential to avoid new flood risk, to prevent and to reduce existing impact of floods and to manage residual flood risk. This study first brief reviewed several historical flood events worldwide, and especially the applications of flood risk treatment of the study areas in France and in Taiwan. The effectiveness and problems of the applications were also analysed and summarised. Then, since Agent-Based Models (ABMs) are ideal tools for simulating the actions, reactions and interactions of autonomous individuals and the environment in a complex system, in order to evaluate the effectiveness and outcomes of flood risk reduction strategies, this study employed an ABM, NetLogo, to analyse the possible interactions of human behaviour and the environment with different strategies. A coupled ABM was developed, combining (i) an evacuation model, for the agent simulations to investigate possible evacuation process during flood, and (ii) a cellular automata (CA) 2D overland flow model, for inundation simulations. The study aims to investigate and to improve existing flood risk management, to raise public crisis awareness and to enhance community-based flood risk management.
