Wave‐Induced Pressure under Gravity Structure

Abstract
The wave‐induced seepage flow in a porous seabed in the neighborhood of a gravity structure is solved exactly by two‐dimensional potential flow theory. The distribution of the hydrodynamic pore‐water pressure along the base of the structure and the wave‐induced vertical force on the structure are computed from the integral solutions. The effects of the thickness of the porous seabed and the width of the structure are examined. Results obtained from the exact theory are compared with experimental data and there is reasonable agreement.
