【 摘 要 】

The influence of the angle of the incoming wave on the stability of a placed block revetment on a filter layer has been investigated. A computer program is described to simulate the flow in the filter layer for various wave conditions. The flow in the filter layer together with the wave conditions determine the loading on the revetment. Two different boundary conditions have been studied, A schemed wave pressure distribution based on results obtained for wave loading perpendicular to the revetment and regular waves measured in a wave basin. The results show that for regular waves the influence of the angle of the incoming wave on the loading of a placed block revetment is small for a revetment with a leakage length equal or larger than the wave height. Oblique incoming waves can result in a considerable increase in loading when the leakage length is much smaller than the wave height and near transitions in the revetment.
