Rubble-mound Breakwater Wave-Attenuation and Stability Tests, Olcott Harbor, New York: Coastal Model Investigation Final Report

A 1:20-scale experimental model investigation was conducted to investigate the wave transmission response of a breakwater proposed for Olcott Harbor, New York A check of the structure's stability showed the proposed section to be conservatively stable. Therefore, an alternate plan also was investigated in an attempt to reduce construction costs for the breakwater. Based on model tests results, it ,as concluded that: a. Both plans tested are stable designs for the maximum wave heights that can be expected to occur (6- to 10-sec waves at still-water levels of +4.3 and +5.1 ft. low-water datum). b. Maximum transmitted wave heights were 0.9 and 1.5 ft. for Plans 1 and IA, respectively.
