The Numerical Study Of SWMM-Based Urban Sewer System Simulation In Qingshanhu District Of Nanchang

The problem of urban waterlogging is getting more and moreattention-attractable all over the world nowadays. This dissertation works on doingresearches of the stormwater process under the circumstance of real rainstorm; theSWMM model is used to analyzing the selected example of Qingshanhu District.Findings are listed below:(1) This dissertation firstly introduces the understanding of SWMM model andpreliminarily establishes the urban sewer system model of Qingshanhu District; themethods of sub-catchment delineation, model parameters selection and modelcalibration process are used in the process of establishing system model.(2) This dissertation firstly introduces the understanding of SWMM model andpreliminarily establishes the urban sewer system model of Qingshanhu District; themethods of sub-catchment delineation, model parameters selection and modelcalibration process are used in the process of establishing system model.(3) The urban sewer system model of Qingshanhu District evaluates theflood-carrying capacity of current water discharging pipeline system and finds out theflooded streets and overloaded pipelines when typical rainstorm comes. Moreover,useful solutions are suggested to solve the problems in the dissertation.
