Abstract
The hydraulic stability of the armour layer of rubble mound breakwaters has been widely discussed in literature and several empirical formulas have been proposed for design purposes. Nevertheless, few studies focused on the armour stability in case of water depth limited water conditions. The aim of the present research is to provide more insights into the stability of the armour layer including extremely shallow water conditions. New 2D physical experiments have been carried out at the EUropean Maritime and Environmental Research (EUMER) laboratory of the University of Salento (Lecce), in presence of a 1:30 foreshore. Tests aimed to investigate both the nearshore hydrodynamics and the hydraulic armour stability under different irregular wave loading. In the present paper the experimental set-up is described together with the main preliminary results. Specifically, the measured damage S after each test in different shallowness conditions is reported and discussed. Experimental results are also compared with the damage evaluated from the empirical formula proposed by Van Gent et al. (2003), in order to investigate the predicted damage level in the shallowness range analysed.
