Sediment pick-up in combined wave current flow

This report presents the experimental methods used in, and tabulates the data obtained from, experiments in the Pulsating Water Tunnel at HR Wallingford. They were made over an immobile gravel rough bed, to investigate the hydrodynamics of wave-current boundary-layer interaction, and over a fine sand bed, to investigate the pick-up, suspension and transport of sediment by combined waves and currents.
