In the presence of a current field the wave action and not the wave energy is conserved. The main effect of the current on the waves is that the current velocity has to be taken into consideration in calculating the propagation speed of the wave action. Furthermore, the effect of the current on the source functions is also taken into account. The current condition can be specified in three different ways
· No current
· Specified current variation
· Current variation from HD simulation
Selecting the specified current variation option you must specify the velocity components in m/s. Note, that the last option is only possible using the MIKE 21/3 Coupled Model FM and only if the Hydrodynamic module is included.
