Abstract

Stability of low crested rubble mound breakwaters under wave attack I. Siladharma, M.G. Satish Dalhousie University, Halifax, NS, Canada Abstract This paper discusses the results of the experimental study being carried out using physical model tests of low crested rubble mound breakwaters exposed to irregular wave conditions. The stability of the structure under wave attack will be investigated. The effect of water depth, slope angle, core permeability and incident wave characteristics are studied. Evaluations are being made for each section of the breakwater such as the front slope (FS), the crest (C), and the back slope (BS). The results of the study will be presented. 1 Introduction Sandy beaches in tropical areas are specially suitable for the growth of reefs. In such beaches protection occurs naturally from coral reefs in front of thebeaches. The coral reef functions as a breaker of the wave energy, which causes damage to the beaches through the wave breaking proces
