"A STATISTICAL TOOL FOR BREAKWATER DESIGN"

Rodolfo Silva, Georges Govaere, Francisco Martin

Abstract


This article presents a methodology for the design of breakwater dikes which includes wave estimation, evaluation of the runup at the dike, calculation of the dynamic and pseudohidrostatic forces operating on the crown wall and finally the estimation of the stability of the armour units in the main layer. The methodology presented is a development of existing experience in the evaluation of the effects produced by regular or monochromatic waves on structures (stability of pieces, induced forces and flow on the slope). This experience is extended to irregular or spectral waves via statistical distribution of waves, taking account of parameters such as root mean square or significant wave height, mean or peak period and water depth. The application of the methodology described here has given satisfactory results compared with those of other methodologies and experimental data from various researchers.
