Abstract:
In the process of urban construction, it is necessary for water supply channels to strengthen their ability to withstand sudden pollution accidents. Taking the water supply channels of Haikou city in the lower reaches of Nandu River as an example, we established a hydrodynamic and water quality model and used it to analyze the arrival time and impact duration of pollutants. We proposed that check sluices and emergency channels should be built ahead of the Longtang intake to guide the pollution clouds generated from accidents in the upper reaches into the emergency channel. According to the simulation results of the hydrodynamic and water quality model, this measure could reduce effectively the amount of pollutants in Nandu River and prevent sudden water pollution accidents from affecting the water supply of the channels.
