Book Description

The entire Dana Point area that will be enclosed by Dana Point Harbor and sufficient adjacent coastline and offshore bathymetry to permit accurate simulation of storm-wave action were reproduced in a 1:100-scale hydraulic model equipped with wave-generating and wave-height-measuring devices. The purpose of the model study was to determine the effectiveness of the proposed breakwater system and inner-harbor basin in providing protection from storm action for pleasure craft and fishing boats berthed within the harbor. It was concluded that the proposed breakwater system, which consists of a 5500-ft-long west breakwater and a companion 2250-ft-long east breakwater with a 600-ft-wide navigation entrance at the southeast corner of the harbor, will provide the degree of protection required for small boats to berth safely in the partially enclosed inner-harbor basin. Investigation of the wave-transmission problem, concerning the degree of wave energy that can reach the inner harbor through the interstices of the proposed rubble-mound breakwaters, showed that the wave energy transmitted to the inner basins of the harbor through the outer breakwater structures is not critical.
