Abstract
Reasonable and economical repair plans for coastal structures, which have passed after completion for several years, could be put into practice by verifying the validity using the latest knowledge, model experiment, measurement equipment and analysis techniques. This paper aims to re-evaluate the wave overtopping characteristics of existing low crested seawall with drainage by an irregular wave hydraulic model experiment.
As a result, the current design has safety margin for wave overtopping and impact wave force by wave overtopping will not significantly affect the stability to the drainage. In addition, applicability of CADMAS-SURF/2D is confirmed as a method for study of wave overtopping characteristics for this type of seawall by calculations of the model experiment.
