EXPERIMENTAL STUDY ON RESILIENT STRUCTURES FOR COASTAL DIKE AGAINST UNEXPECTED HIGH WAVES

Abstract

 Resilient structures for coastal dike against waves higher than the design wave had been proposed by studying failure mechanisms on the seaward and landward of the coastal dike. However, these studies were conducted with hydraulic experiments separately dealing the deformation on the seaward and landward of coastal dike, in which the interaction between the seaward and landward deformations was not considered.

 In this study, the hydraulic experiments on resilient structures on the both seaward and landward of coastal dike against unexpected high waves were carried out. As the results, it was confirmed that the vulnerability against scouring was higher on the seaward than on the landward of the coastal dike, and that the deformations on the seaward and landward of the coastal dike could affect each other.
