Distribution of Pollutants in Nandu River Estuary in Different Environments by FANG Mingyi, SHI Haoran, HAILAI Yibo, LI Haisheng, MING Rui

“…In view of the frequent tropical storm surge in Nandu River Estuary in recent years,the increasing population in Haikou City each year,severe pollution emissions,and increasing upstream water use year by year,this paper studies the pollutant distribution in Nandu River Estuary under the storm surge and reduction of upstream water inflow on the basis of the hydrodynamic-water quality model.In addition,the changes of pollutants under different environments are analyzed.The results demonstrate that pollutants are mainly distributed on the left bank of the river and are mainly in striped shape due to the topography of the river.When the upstream flow is reduced by 20%,the effect of the tidal current is more significant,and pollutants are greatly affected by convection;the pollution zone becomes narrower,and the diffusion distance is the farthest.When the downstream tidal level is raised by 0.4 m,the interaction between the upstream inflow and tidal current is obvious;the flow rate decreases,and the pollutant retention is serious.In this case,pollutants mainly diffuse to the upstream by diffusion.Therefore,the upstream water resources should be effectively regulated and used,and the water surrounding the sewage outlet should be monitored with more efforts to provide a reference for the water environment management of the estuary section of Haikou City in the future.…”

Design and Realization of Jiujiang Urban Smart Water Platform Based on Digital Twin Technology by CHEN Guobiao

“…Nowadays,the digital technology based on digital twin is becoming increasingly mature.To make the water environment treatment of the Yangtze River stable and efficient for a long time,Shanghai Investigation,Design & Research Institute (SIDRI) adopted the advanced concept of smart water in the water environment treatment of the central urban area in Jiujiang,the first pilot city of the Yangtze River Protection,and developed a smart water platform with the digital twin as a core technology.With the digital twin technology,SIDRI built the data base of the city and applied the smart water platform combined with 5G Internet of things,hydraulic modeling and cloud computing technology.Integrating the data of river water regime,water quality,regional rain regime,pump station operation,real-time monitoring of pipe network and other water management content,SIDRI created a spatial-temporal model of the water environment in Jiujiang central urban area with the platform,which improves the efficiency of comprehensive treatment and integrated operation of “plant-network-river-lake-(bank).” …”

Simulation on Water Diversion Regulation Effect in the Central Ditch of Hengqin New District,Zhuhai by LONG Xiaofei, WU Yaju, FAN Qunfang, ZHU Song, WANG Hua, ZHU Jinhe

“…The tidal river network area of the Pearl River Delta uses the ebb-and-flow differences between tidal level of the outer river and water level of the inland river to divert clear water for regulation.This is an effective way to improve the water environment of the tidal river network.The central ditch of Hengqin New District is in the tidal river network area of the Pearl River Delta.To improve the water environment of the central ditch in Hengqin New District,this study builds a one-dimensional hydrodynamic mathematical model of water quality and investigates the hydrodynamic regulation scheme for improving the regional water environment.Then,the water exchange effects of the original regulation scheme and the optimized regulation scheme are calculated and analyzed.The simulation results show that the optimized regulation scheme increases the regional flow rate by 0.20 m/s,shortens the half-exchange period by 101.5 h,and increases the water exchange rate by a factor of 1.1,which demonstrates a great improvement effect on the regional water environment.The results can be used as a reference for the implementation of the water diversion regulation scheme in the tidal river network area.…”
