Abstract

Abstract: Sudden water pollution in the Yellow River have brought serious economic and social losses to the basin. To better study the characteristics of pollutant transport due to aforementioned water pollution downstream of Xiaolangdi Reservoir, a mathematical model coupling of rainfall-runoff, hydrodynamic and advection-diffusion simulation was established. The emergency response to pollutant transport was analyzed by adjusting discharge of the Xiaolangdi Reservoir. The results show that the discharge is non-linearly related to the arrival time of pollutant at some important sections such as the downstream water intakes, duration and peak concentration. Moreover, compared with the previous data, the discharge from Xiaolangdi Reservoir reduced, while pollutant's arrival time was relatively longer, which means emergency response should take more time. However, the dilution for pollutant concentration decrease relatively as discharge increases. The results can be used for reference considering scientific emergency operation in Xiaolangdi Reservior to deal with sudden water pollution downstream.
