Abstract

The design of a breakwater requires that the failure modes which can affect its security, functionality and operationality in its useful life are bounded. The failure modes can be verified by means of the corresponding verification equation. In this work, a unified methodology to verify simultaneously the failure modes produce by wind waves in front or face of the breakwater is presented. This methodology is based on formulate the verification equations of the failure modes forced by wind waves in the front or face of the breakwater in terms of the kinematic and dynamic variables of the flow at these locations. It has been applied to analyse the failure mode that considers sliding of the crown wall. Results show that the parameters of the pdf of these variables depend on the total wave height at the same location and therefore, the verification equation can be also formulated in terms of this variable.
