Book Description
Tests were conducted on 1:50- and 1:100-scale models of rubble-mound breakwater sections constructed of quarrystone to obtain data for design of a stable rubble-mound breakwater which will allow a minimum of wave energy to pass through and over the structure into the protected area of the marina, to obtain design data for wave absorbers on the fairway side of the interior mole, and to determine the relation between wave transmission in a 1:50-scale model and in a 1:100-scale model.

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.
