Abstract : The entire Half Moon Bay Harbor basin, the surrounding breakwater system with 600-ft-wide navigation entrance, and sufficient coastline and offshore hydrography to ensure accurate simulation of approaching waves were reproduced in a 1:100-scale hydraulic model equipped with wave-generating and wave-height-measuring devices. The model was used to determine the optimum location and length of breakwaters necessary to provide, at minimum cost, adequate protection for pleasure craft and fishing boats berthed at the piers during storm wave action. It was concluded that an added section of rubble-mound breakwater about 1050 ft long, which would extend the existing west breakwater in a southeasterly direction and provide a revised navigation entrance about 350 ft wide, would ensure the desired protection.
