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.

近岸的沿岸流主要是由传入海浪的破碎驱动的。这些洋流在沉积物输送造成的海滩侵蚀、幼虫输送和废物扩散方面发挥着重要作用。目前这些电流的数值模型很常见，但依赖于近似值，可能无法捕获导致这些流动的所有小规模过程。特别是，当前的模型在应用于禁止海滩时经常会失败。该项目将使用涡度模型和统计力学模型来探索波驱动涡动力学对流动的影响。
