New wave-driven Vortex Dynamics and Longshore Currents on Barred Beaches

近岸的沿岸流主要是由到来的海浪破裂驱动的。这些水流通过泥沙的输送以及幼虫的输送和废物的扩散，在海滩侵蚀中发挥重要作用。目前这些海流的数值模型很常见，但依赖于可能无法捕捉到导致这些海流的所有小规模过程的近似值。特别是，当前的模型在应用于沙洲海滩时往往会失败。本项目将使用涡量模型和统计力学模型来探索波浪驱动的涡动力学对流动的影响。

Longshore currents in the nearshore are primarily driven by the breaking of incoming ocean waves. These currents play an important role in beach erosion through sediment transport and in larval transport and wastewarder dispersal. Current numerical models of these currents are commonplace but rely on approximations that may not capture all of the small-scale processes responsible for these flows. In particular, current models often fail when applied to barred beaches. This project will use a vorticity model and a statistical mechanical model to explore the effects of wave-driven vortex dynamics on the flow.
