Abstract
Breakwaters can be broadly classified into overtopping and nonovertopping structures. In the case of a nonovertopping breakwater, either the crest level is designed in consideration with the maximum run-up level or a concrete crown wall is provided at the crest on the ocean side of the breakwater to avoid or minimize overtopping. It is essential to understand the wave-induced dynamic and uplift pressures exerted on the vertical face and base slab of the crown wall to incorporate this information in the design. The recently introduced armor block KOLOS, a modified version of DOLOS, is considered for detailed investigation of its hydrodynamic characteristics. Empirical relations have been proposed for the wave-induced pressures caused by regular waves on the crown wall fronted by KOLOS through a comprehensive experimental program. The overall results, compared with a breakwater fronted by natural rocks, indicate that the KOLOS armor layer offers better wave energy dissipation and results in minimal pressures induced on its crown wall.
