The above figure shows wave height (contours) and wave-induced currents resulting from the breaking of regular, 8.0 s, 1.0 m waves around a small bay.

The COAST-L model is a computer model for the simulation of wave-induced nearshore circulation. The model is composed of two independent, but fully dynamically coupled modules; a combined refraction-diffraction wave module and a depth-averaged coastal flow module.
The wave module uses a wave-period averaged technique and so can be used over areas ranging from tens of meters to tens of kilometers. Approximate non-linear effects are included and both swell waves and random waves can be simulated in the surf zone. Full wave-current interaction between internally generated or externally imposed flow fields is also included.
The flow module computes the depth-averaged flows resulting from any combination of wave, wind and tidal forcing. Sophisticated combined wave-current friction and two equation k-ε closures are included.
The COAST-L model can be run in wave-only, current-only or wave-current modes. A non-linear version, COAST-NL, can be applied where warranted.
