Problems solved by technology

However, current research still needs to focus more on DCIA rather than TIA
In addition, the current research is mostly conducted on a small scale and based on a single precipitation event. How to conduct research on a larger scale and for long-term rainfall data still needs further development

Abstract

The invention discloses an urban hydrological simulation system and a simulation method, which relate to the technical field of urban precipitation management. The invention includes a rainfall floodmanagement model, the simulation system includes a time-varying precipitation unit, a surface water evaporation unit, a snow cover and melt unit, a depression interception unit, a soil seepage unit, agroundwater recharge unit, a groundwater and drainage pipe exchange unit, a slope catchment unit, a LID control unit, a region editing unit that are associated with the rainfall flood management model, and the simulation system further comprise a storage module, an aquifer editing module and a groundwater flow editing module. The invention has comprehensive simulation function and can provide comprehensive and representative analysis data through a complete functional system unit structure. The influence of DCIA and TIA setting on runoff generation in urbanization region is analyzed under thepremise of comprehensive consideration of parameters. More objective and accurate reference and opinions are provided for urban planning.

Description

technical field [0001] The invention belongs to the technical field of urban precipitation management, in particular to an urban hydrological simulation system based on SWMM model. Background technique [0002] The development of urbanization has profoundly changed the regional hydrological cycle process and had a significant negative impact on the water environment. Urbanization changes the underlying surface of the city from a permeable area to an impermeable area, and through the urban heat island effect, changes the temporal and spatial distribution of precipitation in the watershed and the effect of rainfall runoff. These changes are related to the water cycle of the watershed. The process, utilization and regulation of stormwater resources are closely related. Highly developed urbanization puts forward higher requirements for the development of urban drainage system and the theory of urban production and confluence. [0003] Generally speaking, the urban drainage sys...
