CMS-Flow:Wave-current Interaction

Wave-current Interaction

The characteristic velocities $c_x$, $c_y$, and $c_{\theta }$ are calculated as

    $c_x=c_g\cos \theta +U$
    $c_y=c_g\sin \theta +V$
    $c_{\theta }=\frac{\sigma }{\sinh 2kh}(\sin \theta \frac{\partial h}{\partial x}-\cos \theta \frac{\partial h}{\partial y})+\cos \theta \sin \theta \frac{\partial U}{\partial x}-{\cos }^{}\theta \frac{\partial U}{\partial y}+{\sin }^{}\theta \frac{\partial V}{\partial x}-\cos \theta \sin \theta \frac{\partial V}{\partial y}$

Symbol	Description
$\sigma$	Wave frequency
$N$	Wave action
