The initial report on the 'unified waves model' describes a procedure to compute water wave propagation over long distances accurately at low cost, and for a wide variety of physical situations. This report outlines recent developments that extend it

The governing equations for a moving hydrodynamic surface lead to a local conservation law for a surface velocity variable qs not in common use. When the surface is closed and applied forces are conservative, the law reduces to Kelvin's circulation t

An experimental study has been made of the propagation of ultrasound in liquids under both free‐field and guided‐wave conditions. Free‐field measurements have been made from 1 to 20 Mc in low absorbing liquids, employing both circular and squar

A theoretical study is made of attenuation of ultrasound in cylindrical and rectangular waveguides. The systems treated consist of a piston source radiating into a bounded, inviscid fluid and a receiver of the same size as the source. Expressions for

Satellite SAR and airborne SLAR produce strong surface imagery of bottom features in shallow seas. Lagrangian and Eulerian current measurements have been made in the vicinity of a sand ridge that generates a visual and remotely-sensible wave manifest

Direct measurements of the turbulent structure of a benthic, tidal boundary layer have been made by recording several time series of simultaneous horizontal and vertical velocity fluctuations at various distances above the bottom. For the duration of

Radar observations of the ocean surface can image features of the floor of shelf seas. The radars, however, respond to water waves that never feel the bottom directly, because they are too short to do so. Wave-current interactions are a mechanism tha
