Abstract


An alternative berm type breakwater was proposed at the South Breakwater of the Typhoon Shelter at Hei Ling Chau, Hong Kong. The required berm width and the stone sizes were initially determined using a numerical model. The proposed berm breakwater was then tested using physical modelling approach. The testing programme made use of both two dimensional and three dimensional hydraulic model studies to assess the stability of the trunk and head sections respectively. Both tests confirmed that the proposed berm type breakwater would perform satisfactorily and the reshaped profiles would not encroach on the core material.
