SCALE EFFECT TESTS FOR RUBBLE-MOUND BREAKWATERS: Hydraulic Model Investigation

Laboratory investigations conducted by and for the Waterways Experiment Station under ES 815, "Stability of Rubble-Mound Breakwaters," determined the relative importance of the different variables with respect to the stability of rubble-mound breakwaters and formulated design criteria for those structures. In ES 815, test-wave dimensions, water...

Hydraulic characteristics of mobile breakwaters composed of tires or spheres

Two new types of mobile breakwaters consisting of tire and sphere assemblies, respectively, were tested. Tests covered a wide range of wave conditions, water depths, and breakwater dimensions. Experimental measurements were made to determine the wave reflection and wave transmission coefficients, the power dissipated by the breakwaters, and the...
