' Prototype dimensions. 



(i) Plans Tested . Tests were first performed with existing 

 prototype conditions installed in the model (Fig. 4-29). Before tests of 

 the various improvement plans, comprehensive base test data were obtained 

 in the harbor and bay area and then used as a base to determine the rela- 

 tive efficacy of the various improvement plans. Model tests were conduc- 

 ted using two basic harbor configurations: double entrance (plan 1, Fig. 

 4-30) and single entrance (plan 2, Fig. 4-31). Typical sections of the 

 various breakwater and revetment structures are shown in Figure 4-32; 

 breakwater, mole, and basic designations are shown in Figure 4-33. 



(j) Description of Tests . For the long-period wave phase 

 of the investigation, the wave generator was calibrated using the Marine 

 Advisers' (1964) data for sensor No. 1. In each individual wave period, 

 the wave generator stroke was adjusted until the required wave height was 

 recorded at the location of sensor No. 1 (gage 37 in the model). The 

 corresponding input wave at the wave generator was then used for all 

 subsequent base tests and tests of the two improvement plans. Prelimi- 

 nary mode of oscillation tests was conducted in which wave heights were 

 measured over the entire bay area of the model for base test and plan 1
