A 1:100-scale model of Port San Luis (formerly known as San Luis Obispo Harbor), California, and sufficient offshore area to permit generation of the required test waves was used to investigate the arrangement and design of certain proposed harbor improvements with respect to wave action. The proposed harbor improvements consisted of (a) an 1150-ft-long south breakwater extending East-northeast from Smith Island, with a 370-ft-long breakwater wing extending northward from this structure; (b) a 3515-ft-long detached breakwater with a north-northeast to south-southwest alignment, located approximately 500 ft seaward of the Port San Luis Wharf; (c) a 1300-ft-long north breakwater extending from a point on shore southward toward the north end of the detached breakwater; and (d) development of the inner harbor by constructing landfill areas and boat slips for the anchorage of small pleasure craft. A 60-ft-long wave machine and electrical wave height measuring and recording apparatus were utilized in model operation. Base tests were conducted with existing prototype conditions installed in the model. Results of tests involving the various improvement plans were compared with base test results to determine the relative effectiveness of the respective plans. (Author)
