Abstract: Abstract In the eventuality of a dike-break flood, evacuation is regarded as the primary solution for disaster mitigation and it usually needs to be performed in a quick yet orderly manner. In order to have a good response to such emergency situation, it is necessary to prepare a feasible evacuation plan and carry out related analysis of it. Based on this purpose, this paper presents a methodology of emergency evacuation planning for dike-break flood. Aiming to suit the specialty of certain dike-break flood condition, we conducted related data analysis and processing such as flood simulation in MIKE, and impassable flooded roads extraction in ArcGIS. An evacuation model is established, and successive approximation algorithm is applied to obtain a feasible optimized evacuation scheme in the model. Furthermore, based on this methodology, a geographical information system-based decision support system for study area is developed. By using it, decision-makers can acquire reliable situational information of flood evolution, feasible routes, road congestions and high-risk groups. Thus, they can mobilize necessary resources in a timely manner to coordinate an effective emergency response.
