Wave Transmission on Submerged Rubble Mound Breakwater Using L-Blocks

Laboratory tests on a permeable submerged rubble mound breakwater (SRMB) constructed using L-Blocks armour unit with 40 tests for wave transmission were analyzed and the available empirical equations for wave transmission coefficient (Kt) were evaluated. The ranges of variation were 0.23< ds /d&...
