Simulation of Pollutant Transportation in Yinluan Open Channel under the Effects of Wind

Abstract

The water diversion project from Luanhe River to Tianjin is a large-scale project eliminating 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 was built and the transportation of pollutants in Yinluan open channel with the effects of wind was simulated by EFDC model. The evolution and affective area of pollutant in Yinluan open channel was obtained. The results showed that the effects of wind on the transportation of pollutant in Yinluan open channel are strong when the wind direction is along the channel.

Spatio-Temporal Evolution Model of the Hydraulic Transport Characteristics of Particulate Solids

“…Thus, the pipeline should be rotated regularly to improve its safety and economic performance. For transportation in an open channel, under the influence of the unsteady velocity distribution, the erosion intensity of the slurry on the trough bed evolves gradually, and the slurry concentration and velocity distributions should be closely monitored to ensure the safety and reliability of the construction (Zhang et al, 2013). Therefore, the temporal and spatial evolution of the characteristics of particulate solid transportation affects the stress state of particles (Yu et al, 2015), the ability of the fluid to transport particles, and the variation in the hydraulic gradient (Kaushal and Tomita, 2003).…”

Risk Grading of Water Pollution Event with Applying Pollutant Transportation Simulation

“…It mainly contains the modules of hydrodynamics, water quality and sediment. It can be used to simulate three-dimensional flow, eutrophication process and sediment transport of surface water systems, such as the harbor hydrodynamic process [8][9][10][11], algae growth prediction [12][13], dissolved oxygen distribution [14], water age analysis [15][16], sediment transport [17][18], accidental water pollution [19] and so on.…”
