Abstract
The design of breakwater in deep water involves consideration of all the aspects of structural stability, economic viability and the construction feasibility. The main objective of this study was to assess the hydraulic stability of the breakwater against design and overload waves and assess the toe stability for possible low water levels using 2D (Flume) physical model study. The breakwater is located at −18.0 m chart datum (CD) and crest and the toe is at +7.6 m CD and −7.0 m CD respectively. The breakwater was hydraulically stable for the series of waves applied for the structure including overload waves while showing negligible damage to the 2–4 T toe for low water levels (+0.11 m CD and −1.39 m CD). The simulation of different toe elevations with low water levels is shown in Fig. 10.
