Inland discharges into reservoirs often carry rich nutrients, pollutants and biological species into the coastal regions, which are redistributed across the central regions of reservoirs through dynamical mixing processes. One of the important mixing processes is the horizontal exchange flow between the near shore and central regions induced by diurnal heating and cooling through the water surface, which is classified as a natural convection process. This process will be investigated in this project through a closely linked analytical, experimental and numerical research program. The output from this research will have direct application in water quality management and environmental planning.

内陆排放到储层中通常将丰富的营养物质，污染物和生物种类带入沿海地区，沿海地区通过动态混合过程在整个储层中心区域重新分布。重要的混合过程之一是昼夜加热和通过水面冷却引起的近海和中央区域之间的水平交换流，该水面被归类为自然对流过程。该过程将在该项目中通过紧密相关的分析，实验和数值研究计划进行研究。这项研究的产出将直接应用于水质管理和环境计划。
