Technical research on analysis of dam-break emergency evacuation

Analysis of dam-break emergency evacuation is one of the important non-engineering measures to avoid or reduce loss of life due to dam-break. It is mainly reflected in the perspective of time and space. Aimed at escape, of the dam-break emergency evacuation is to determine the response-time requirements by analyzing transfer time before dam-break and arrival time of flood. Space analysis primarily includes calculation of flood submerging range and space requirements of dam-break evacuation, depending on submerging range of dam-break and population at risk. Both dam breach simulation and dam-break flood routing simulation are the fundamental work. The distribution forecast of population at risk and calculation of time-consuming of emergency evacuation are based on flood analysis simulation, which are considered as the important parts of analysis of dam-break emergency evacuation. This paper is to analyze and summarize the researches on these four above-mentioned technologies and currently applications.
