%X :To prevent from and control the effect of emergent water pollution accident in reservoir area, the temporal and spatial variations of pollutants in the reservoir after the accident were simulated by a 3-D model coupling hydrodynamics and water quality at typical working conditions. Factors of hydrology, meteorology and contaminant movement were taken into account. A large reservoir in the northeastern area of China was taken as a case study. Results revealed that affected by inflow and dominant wind in northeast direction, the contaminants spread toward the direction of the dam site along the southwest coastline, and the area of standard-exceeding contaminants increased gradually; but the concentration of contaminants decreased gradually with the flow process. Through simulation of the water quality, the spatial distribution of contaminants is quantitatively obtained, which offers technical basis for emergency treatment.
