Nonlinear Wave Evolution in Interaction with Currents and Viscoleastic Muds

A numerical model is extended to investigate the nonlinear dynamics of surface wave propagation over mud in presence currents. phase-resolving frequency-domain for wave-current interaction improved account modulations due viscoelastic arbitrary thickness. The compares well with published laboratory data and performs slightly better than viscous mud-induced damping mechanism. Monochromatic random simulations are conducted examine combined effect currents, dissipation modulation, wave-wave interactions on spectra. Results indicate that current effects not as straightforward mud. For example, while opposing currents consistently increase waves mud, they can decrease high variations frequency-dependent stemming from mud’s elasticity. It shown a assumes layer be thin simplification overestimate thick layers.
