Modeling And Simulation Of Urban Waterlogging Emergency Management In Wargaming System

Our country has a stability increase in both economics and urbanization level after China’s accession to the WTO. Meanwhile the regulation of rainfall runoff has changed greatly with the changes in urbanization areas and underlying surface in the city. Under the condition of the same rainfall, the urban runoff increases due to the increase in impervious area, so is the runoff coefficient and peak flow. Hence there is a great trouble for city to preventing flood and protecting people’s lives and property security. It is of great significance for strengthening the command ability and joint rescue ability to build the emergency management wargaming system of urban waterlogging.Combining with modern computer technology and information technology, and applying the wargaming method, the process of urban waterlogging can be presented. Building the urban waterlogging wargaming system is the current hot spot to prevent waterlogging disasters, and is benefit to both economy and society. This paper builds the urban waterlogging model and emergency management evaluation model based on wargaming. The process of urban waterlogging is simulated and the rescue work of government sectors is drilled. Then we evaluate the rescue work and put forward the shortage of current urban emergency management and the solution to copy with urban waterlogging. The main work of this paper is as follows:1) This paper consults some wargaming information in domestic and overseas, and sums up the development and application of wargaming in China, and points out the importance of wargaming in the urban waterlogging emergency management system;2) This paper builds the rainstorm model in Jinan, summarizes the calculation methods of urban surface runoff, and establishes rules to solve the urban surface water yield which is applicable to wargaming system;3) This paper designs the scenario and rules of wargaming system in Jinan, according to the altitude information from Google Online and the responsibilities of each department in urban flood control emergency plan;4) This paper establishes time-based evaluation system according to wargaming rules;5) This paper offers a proposal for Jinan to response to the urban waterlogging according to the final evaluation result.
