There has been no unified method for the syntaxis of design standards of urban drainage and waterlogging drainage up to now. In order to study the standard syntaxis for two scenarios(municipal drainage of a one-year frequency storm flood with waterlogging drainage of a five-year frequency storm flood, and municipal drainage of a one-year frequency storm flood with waterlogging drainage of a ten-year frequency storm flood)in the Donghaochong Catchment, a two-dimensional urban storm flood model which couples underground drainage pipes, rivers, and surface ground was established using Infoworks ICM, providing technical support for the planning and design of urban drainage waterlogging. The results show that waterlogging will not occur in the Donghaochong Catchment with the combined standards for municipal drainage of a one-year frequency storm flood and waterlogging drainage of a ten-year frequency storm flood. However, the distance from the pipe outlet bottom to the river bottom also impacts the water level in the pipes. Therefore, it is suggested that the elevation of the pipe outlet bottom should be 0. 5 meters higher than the river bottom elevation in the design of urban drainage networks.
