Spatiotemporal Characteristics of Water Age in the Largest Freshwater Lake in China
Publication: World Environmental and Water Resources Congress 2019: Hydraulics, Waterways, and Water Distribution Systems Analysis
ABSTRACT
Water age is an important indicator for describing water exchange and pollutant transport in the lake. As the largest freshwater lake in China, Poyang Lake, with complex hydrodynamic condition is encountering serious environmental issues in recent years, for example water quality deterioration. A two-dimensional hydrodynamic model basing on environmental fluid dynamics code (EFDC) is established to calculate the water age in Poyang Lake. The results show that the water age in Poyang Lake has obvious spatiotemporal characteristics. The largest month is August, the smallest month is April. From the perspective of space, the water age in the main channels are significantly smaller than the bay regions. This paper make a quantitative analysis for water age, which will be helpful in understanding the hydrodynamic processes and benefit water quality management in Poyang Lake.
