Investigation of the forces on a submerged cylinder due to surface water waves

The results of a laboratory investigation of the wave induced forces on a submerged cylinder are reported. Force and pressure distributions on a cylinder located on and near a wave basin floor are correlated with surface water waves of varying amplitude and period. The horizontal and vertical components of forces on the cylinder are registered by strain gage outputs and by measuring pressure distributions around the cylinder with pressure transducers. The results of this laboratory study are being used as the basis for planned in situ experiments with cylinders mounted on or near the ocean floor.
