Transferring Simulation of Pollutants in YinLuan River Open Channel under Traffic Accidents

The water diversion project from Luanhe River to Tianjin is a large-scale project, which solved the water shortage of Tianjin city. Because the long water supply open channel along highroads, the traffic emergent incidents bring great potential dangers to the water supply of Tianjin. In this paper, the prediction model of traffic emergent incidents in YinLuan River Open Channel was built and the transferring of pollutants under typical scenes was simulated by EFDC model. The evolution and affective area of pollutant in open channel was obtained. The results provide a scientific basis for the decision makers to take effective measures.
