Nonlinear models of wave-current interaction

This work has involved the development of new modelling procedures capable of describing the non-linear interaction between waves and co-existing currents, particularly where the latter involves some depth-variation, typically arising due to the effects of the wind shear. Such problems are very difficult to model since the presence of depth-varying vorticity, associated with the current profile, leads to the wave motion itself becoming rotational. In this case the commonly applied design wave solutions, based on the assumption of irrationality, become inappropriate. A new approach based on the theory of fluid sheets has been developed and validated against a wide range of available data.
