Research on Hydrodynamic Force Enhancement and Water Environment Protection Measures of Dachan Bay, Shenzhen
The Pearl River Hydraulic Research Institute, Guangzhou, Guangdong, China
With the research purpose of protection of water environmental quality in Dachan Bay Area in Shenzhen City, especially in National Development Zone in Qianhai Area, this paper establishes a horizontal two-dimensional water quality model of Dachan Bay and its branches by the use of WQ Module of Delft 3D. And this paper respectively simulates distribution of water quality in full high flow year, normal flow year and low flow year before and after the implementation of protection measures, predicts the effect of the water environment protection measures and focuses on the analysis of two kinds of hydrodynamic force enhancement pat-terns, that is, “water replenishing in dead zones” and “pollution discharge at back doors”, and finally recommends water environment protection measures with the core of “pollution discharge at back gates” by taking full advantage of natural dynamic, thus obtaining a better effect than that of the traditional “water replenishing in dead zones”.
Key words: water environment protection / hydrodynamic force enhancement / water quality modeling / Dachan Bay
