Abstract

In view of the demand for emergency response to emergency response to emergency water pollution, the rapid prediction technology for transport and diffusion of contaminated groups is studied. On the basis of relevant research at home and abroad systematically, focusing on flat, inverse slope channels in the transport and diffusion of contaminants in research have been put forward along the fast calculation formula of diffusion and transport of pollutants on the slope channel based on inverse applicability in the case of channel slope, flat slope, and the calculation results and the results of HECRAS software by contrast, try to find a fast calculation method, inverse transport and diffusion of contaminants in the channel slope. The research draws the following conclusions: in the channel bottom slope for flat slope or reverse slope, the deviation was below 20% and the calculated values of the distance simulation of pollutants transport peak, simulated pollutants value and the longitudinal length of the slope channel value deviation value of around 10%, pollutant simulated and calculated values are basically the same, therefore, Shun Po transport fast calculation formula can be used to channel the pollutants in the channel, flat against the slope of pollutant transport and rapid calculation of diffusion characteristic index, this conclusion can provide scientific, efficient and powerful decision support for sudden water pollution emergency control

Key words

water transfer project / open channel / sudden water pollution / emergency response / rapid prediction
