The accuracy of several asymptotic series expansions for wave speed and particle velocity under the crest of a solitary wave (on a fluid at rest) up to maximum height is investigated. The very accurate numerical results of Williams (1985) are the mea

The accuracy of asymptotic expressions for phase, wave energy, and wave action velocities for steady, plane gravity waves progressing in deep water and with no ambient currents is investigated. The calculations are to a large extent based on Fenton

Steady, gravity water waves on a constant-over-depth current, progressing over a slowly varying bed, are studied with the purpose of connecting the wave action flux concept with conventional energy flux considerations. The analysis is two-dimensional

Different syphon type suspended load probes were used together with a specially developed “carousel” sampler for measurements of the instantaneous sediment concentration in turbulent oscillatory flow over a sand bed. Shields parameters were well

A numerical boundary integral equation method combined with a non-linear time stepping procedure is used for the calculation of wave forces on a large, submerged, horizontal circular cylinder. As the method is based on potential theory, all computati

The Bernoulli equation for higher‐order Stokes waves on a steady current over a horizontal, impermeable bed was analyzed, and an ambiguity was detected in the determination of the wave‐induced pressure at even‐order theories. This leads to the

The propagation of non-breaking waves on large-scale currents over a gently sloping sea bed is considered. Effects of vorticity and dissipation are included. The three-dimensional case is studied only for irrotational flow.
