Abstract
Because of the expected sea level rise, most of the human properties located on the coast have to be protected during the present century. One of the engineering alternatives is to build rock sloping coastal structures. Currently, their design has to include procedures for aging and deteriorating to forecast their maintenance and reparation costs during its service life. The objective of the present research is to reformulate the rate of mean damage proposed by Melby and Kobayashi (1998) to predict the progression of mean damage, S, on a given mound breakwater typology under sequences of storms with varying wave conditions and water levels. The proposal is based on the interplay of water depth, h, incident significant wave height, Hs and mean wave period, Tm at the toe of the slope, and the impinging number of waves, Nw (Losada et al.
