Segmented detached breakwaters showing the effects of varying the segment length and the number of gaps; near Rome, Italy (circa 1971) 54. Combined response control techniques. The designer may use a com- bination of the previous techniques to prohibit tombolo formation. The amount and spatial variation of energy reaching the zone behind the breakwater is the sum of transmission from (a) the ratio of structure length to distance off- shore, (b) wave transmission through or over the structure, and (c) diff

When the break- water is positioned well inside the breakers, a large percentage of the total 45.
