针对浅水湖泊风生流对改善湖泊水环境的积极作用,基于水动力模型,建立了二维浅水湖泊风生流数值模型,利用单一变量控制法,综合分析了地形、风向、补水流量等影响浅水湖泊风生流的主要影响因素。以南方某城市浅水湖泊为例,模拟分析了不同方案下的风生流环流强度和流场特性,并由多方案效果综合分析和方案优化,提出了改善湖泊水环境的最佳工程与调控方案。
Aiming at the positive effect of wind-induced flow on water environment in shallow lakes, a numerical model of wind-induced flow in two-dimensional shallow lake was established based on hydrodynamic model. By using single-variable control method, the effects of topography, wind direction, The Main Influencing Factors of Lake Wind. Taking a shallow lake in an urban area of southern China as an example, the wind-induced current circulation intensity and flow field characteristics under different scenarios were simulated and analyzed. Based on the comprehensive analysis of multi-program effects and optimization of scenarios, the best project for the improvement of lake water environment and its regulation program .
