This proposed research has two components: The first component is the investigation of the movement of a sediment mixture in natural rivers. The movement of loose riverbed sediments varies with time and space. It frequently leads to channel erosion/sedimentation, increase of river flood risk, and destruction of fish habitat. The second component is the investigation of counter-flowing, layered fluid exchange in connecting sea straits and channels. Exchange flow can carry oxygen, nutrients and pollutants into or out of a harbour, a lake or a coastal region. Therefore, exchange flow has important water-quality and ecological implications.

这项拟议的研究有两个组成部分：第一个组成部分是调查的泥沙混合物在自然河流中的运动。松散河床沉积物的运动随时间和空间的变化而变化。它经常导致河道侵蚀/沉积，增加河流洪水风险，并破坏鱼类栖息地。第二部分是研究连接海峡和航道的逆流分层流体交换。交换流可以携带氧气、营养物和污染物进出港口、湖泊或沿海地区。因此，交换流具有重要的水质和生态意义。
