The Operational Scheme And Numerical Simulation Of Pollutant Transportation In JinShan Lake

"Jinshan Lake"construction project is a part of the significant special technological project of our country's tenth five-year plan-"ZhenJiang aquatic environment quality improving and ecology restoring technology study and synthetic demonstration". The construction of Jinshan Lake will improve the aquatic environment quality of ZhenJiang City .Basing on the status quo and the outlook of the lake flow-pollutant mathematic model development inside and outside of our country, associating with the "JinShan Lake"construction project,the flow-pollutant mathematic model is established to simulate the flow field and pollutant field under different abstract programs. Further more, the uniformity of the flow-velocity,area of the backwater section and the rate of the water replacement are used as the criteria to distinguish which abstract program is best. Applying this criteria,the abstract programe of JinShan Lake is optimized.Meanwhile, based on the three-dimension model, different representative wind-drived flow and mass transportation in JinShan lake are taken into simulation. JinShan Lake water quality in horizontal and vertical variety simultaneity is found, vertical variety of contamination index to be considered in the lake fluid matter monitors and evaluation is put forward. The study of this paper must be useful to guide the water environment management model of JinShan Lake in the future.
