Abstract

Wave generation problem generated by a moving oscillatory pressure disturbance (time harmonic) at the free surface of a finite depth ocean in the presence of surface tension is analyzed for permeable ocean bed. The governing initial boundary value problem is solved by using Laplace–Fourier transform technique. The method of stationary phase is used to evaluate the asymptotic solution of surface elevation. The asymptotic form of free surface is represented graphically in a number of figures. The influence of current speed, porosity parameter and surface tension on the behavior of surface elevation in the far field has been studied. Dispersion relation is also taken into account. Further, the phase and group velocities of wave motion for variation of parameters have been demonstrated through a large number of figures, and appropriate conclusions are drawn.
