The Unsteady Dynamics of Bouyancy-Driven Coastal Flows

在这个项目中，P.I.将对河口羽流的稳态层模型进行非定常（时变）推广。目的是研究观测到的这些羽流复杂的水平流动结构的机制，这可能是由于它们的非线性动力学，这是现有模型无法解决的。具体主题包括：1；通道内浮力流体的非线性调节2. 河口羽流的演化及其对变流量、环境流量和风应力的响应3. 海岸几何形状对海岸潮流的影响；和4。海岸几何形状对海相层射流的影响。

In this project, the P.I. will develop an unsteady (time-dependent) generalization of a steady-state layer model of estuary plumes. The objective is to study the mechanisms responsible for observed complex horizontal flow structure of these plumes, which is likely due to their nonlinear dynamics, and which is not addressable by the existing model. Specific topics include: 1. nonlinear adjustment of a buoyant fluid in a channel; 2. evolution of an estuarine plume and its response to variable discharge, ambient flow, and wind stress; 3. the effect of coastal geometry on coastal currents; and, 4. effects of coastal geometry on marine layer jets.
