INFLUENCE OF DEFORMATION OF WAVE DISSIPATING WORKS AND LONG PERIOD SWELL ON WAVE PRESSURE ACTING ON CAISSON BREAKWATER

Abstract

 In this study, the influence of deformation of wave dissipating works and long period swell on wave pressure and force acting on the caisson breakwater is evaluated on the basis of the experiments. The model profiles corresponding to the deformation amount are used and the wave pressures are measured under the conditions including the long period swell in the experiments. Moreover, an artificial neural network (ANN) model is applied to the prediction of the horizontal wave force. When the deformation becomes large, the wave force increases considerably. The possibility that the smaller wave height causes the relatively strong wave force in the case of long period swell is also indicated. The ANN model predicts the horizontal wave force within about 30% and the applicability of the model is confirmed.
