Abstract: Laser doppler anemometer measurements of turbulence intensity in oscillatory flow over rough beds are reported. The beds consisted of two grades of sand, gravel, and pebbles, and the measurements were made in an oscillatory ...

Abstract: The motion of sediment in oscillatory flow over a flat bed is investigated both theoretically and experimentally. The theory makes use of results for the relationship between stress and strain in steady flow. The experiments ...

Abstract: The results are reported of an experimental study of the Eulerian time-mean drift induced by progressive water waves over rough beds. Measurements were made in a laboratory flume with a laser Doppler anemometer, and two ...

Abstract: The effects of sediment transport on the fluid velocities and turbulence in oscillatory flow were investigated with the aid of a laser Doppler anemometer (LDA). Measurements were made over flat beds in an oscillatory flow ...

Abstract: Measurements are reported of sediment pickup rates from rippled beds in an oscillatory-flow water tunnel. Two maxima in pickup rate are observed in each half-cycle: The first corresponds to the sediment entrained at flow ...

Abstract: Laser‐Doppler‐anemometer measurements of the fluid velocities in combined oscillatory and steady flow over rippled beds are reported. The direction of the steady current was parallel to the ripple crests and at right angles ...
