Abstract: A 1:120- scale model of Monterey 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 and surge action and to determine current conditions in the navigation entrances to the harbor and its basins. The proposed harbor improvements consisted of (A.) enlarging the present harbor by construction of a detached north breakwater, approximately 3350 ft in length, and a companion east breakwater connected to shore and extending approximately 1100 ft seaward, and (B.) development of the inner-harbor area by constructing moles to form two additional basins for the anchorage of small pleasure craft. A 56-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 various plans. It was concluded from the test results that (A.) either the single-entrance or the double-entrance plan will provide an improvement over existing conditions with respect to long-period surge in the harbor; (B.) although the harbor basins respond to several of the wave periods tested, no serious cases of resonance were noted; and (C.) either the single-entrance or the double-entrance plan will provide sufficient protection to the inner basins from short-period (5 to 20 sec) waves, except in a portion of the east basin. An analytical study of long-period sea-energy oscillations in the vicinity of Monterey Bay with respect to the possibility of related response in Monterey Harbor was conducted, and the results of that study are presented in Appendix A.
