Hydrodynamics and pollutant transport modeling of Poyang Lake, China for the study of downstream engineering controls effect
Poyang Lake, the largest freshwater lake in China, is a key regulator of the hydrology, water quality and ecosystem in the middle reaches of the Yangtze River.Recent industrial development and urbanization in Jiangxi province have driven rapid increase in water consumption and deterioration of water quality, exerting pressure on water utilization in the Poyang Lake basin.In order to assess the impact of the potential barrage on Poyang Lakes ecosystem and surrounding communities, an accurate and representative evaluation of the hydraulic and environmental challenges is essential.In this paper,a numerical model that can simulate the hydrodynamics and water quality of Poyang Lake is used to assess the impact of the proposed downstream barrage on Poyang Lakes hydrodynamics and water quality.The model couples 1-D river network model and 2-D water quality model, and is validated against measured data.It is concluded that the proposed barrages operation has large effects on the ecology and water environment of Poyang Lake, mainly in terms of water volume changes and water resources availability.
