water ecological pattern of sponge city is established. Finally, guided by the problems and target, the

water environment, water safety, water ecology, water resources and other contents are systematically

planned, which can scientifically and systematically guide the construction of sponge city for Doumen

District.

Build of Smart Drainage Management Platform for Central Urban Area of Shanghai ...................................................

...................................................................................................................................................................ZHANG Yanjing( 146)

Abstract

Under the background of rapid rise and development of smart cities, smart water as well as

urban refined and intelligent management, aiming at the characteristics and management demand of urban

drainage facilities in Shanghai, and taking the maximum use and integration of the existing information

resources and sharing the common as the starting point, the research on the build of "smart drainage"

management platform is carried out, which builds the smart support means of solving the urban seeing sea,

reducing the discharging-into-river pollution from the drainage of pumping stations, promoting the

integrated operation of plants, pump stations, nets and tanks, and improving the quality and efficiency of

drainage systems.

Keywords

urban drainage, smart drainage, drainage system, drainage facilities, drainage pumping station

Brief Analysis on Initial Rainwater Abandonment Flow of Anzhou Characteristic Town in Xiong'an New District

......................................................................................................................................................LU Yangyang, HU Xijia ( 149 )

Abstract

The initial rainwater runoff pollution control rate is the key link of urban rainwater

comprehensive control, and is also the key control index of

Sponge City Construction Technical Guide

Planning and Design of Rainwater System for Low-impact Development.

Urban runoff has obvious initial

scouring effect. But due to the randomness and complexity of rainfall scouring process, it is still a difficult

problem to determine the initial runoff abandonment flow under different conditions. Taking the municipal

supporting infrastructure project for the resettlement area of Anzhou Characteristic Town in Xiong'an New

District as an example and taking the initial rainwater interception network of Anzhou Characteristic Town

as the research object, the local study results of the volume regulating method, rainstorm intensity method

and SWMM model analysis method are summarized. And the results of initial rainwater abandonment flow

are compared and checked each other through these three calculation methods. Finally, the initial rainwater

abandonment flow of this area is determined. Hereby, the relationship among the initial rainwater

abandonment flow, runoff pollutant concentration change and runoff pollutant removal rate are further

studied, which provide some reference for practical engineering application.

Keywords

initial rainwater, abandonment flow, rainfall runoff; SWMM, removal rate

Analysis and Preliminary Solution on Waterlogging Problems in Huxi Area of Nanchang High-tech Development

Zone ............................................................................................................................................................... PENG Jiangxi ( 153)

Abstract

Taking Huxi Area of Nanchang High-tech Development Zone as an example, based on the

regional rainfall and terrain data as well as an example, according to the rainfall data, topographic data

and drainage system data of the studied area, the professional dynamic coupling simulation system is used

to simulate the drainage pipeline network, open channel, river, each hydraulic structure and the flow state

of two-dimensional slope water, which can intuitively express the surface runoff and pipeline network

drainage conditions, and find out the waterlogging causes and points. The relevant solution is proposed.

This simulation can also approve the effect after implemented.

Keywords:

dynamic, coupling simulation, waterlogging, solution
