Wave energy transmission through and over low crested breakwaters

In the present paper, a formulation for the estimation of the wave transmission coefficient, Kt, at low-crested structures (LCS) is proposed based on a large laboratory database. The adopted database considers 2D experiments on wave transmission at LCS; it consists of 3327 values of Kt from 33 datasets and includes rubble mound structures with natural and concrete units, as well as impermeable slopes. According to Goda and Ahrens (2008), the wave transmission coefficient is formulated as the summation of the wave energy transmitted over and through LCS. Application of the new formulation showed a good agreement between measured and predicted K-t.
