Simulation and Analysis of Effect on Urban Operation of Urban Storm Water Logging
Great effect on urban climate, hydrological condition, surface condition and urban operation caused by urbanization process, even substantial changes have been taken place, includes heat island effect, decrease of green cover percentage, urban storm water logging, increase of accidents of urban lifeline systems, and so on. At the same time, urban storm water logging brought great negative effect on urban operation and security. The processes of water logging and drainage have been simulated by different software in order to contrast the accuracy of calculation. Different initial parameters, such as parameters of rainfall, hydrographic condition, ecological environment, topographic factor, geological conditions of the city, have played a decisive role in the results of simulation. Influencing factors and formation mechanisms of urban storm water logging, especially the effect on urban lifeline systems, have been analyzed through the simulation. According to the results of simulation, quantified solutions on urban emergency response, optimization of drainage system and improvement of urban planning have been suggested.
