A STATISTICAL MODEL FOR DAMAGE ACCUMULATION IN BREAKWATERS

Carmen Castillo, Rafael Molina, Rebeca Gómez, Enrique Castillo

Abstract


Rehabilitation and maintenance studies are a great concern for Port Authorities and other Administrations.

For a complete risk analysis, probability of failure due to instability of the armour layer must be analyzed and therefore a knowledge on its deterioration rate is needed.

Breakwater armour stability is highly variable and difficult to quantify for many variables are involved in the problem.

Breakwater armour stability is stochastic in nature as both loading and armour conditions are. There is uncertainty in armour placing and shape and in loading by waves and water level.

Dimensionality, compatibility conditions and the central limit theorem are suggested to be considered for building consistent statistical models reproducing random breakwater damage progression due to general random wave actions.
