<p>The harbour, coastal or shore consolidatinq system has an outer structure, e.g mole or breakwater, of upright wave-reflecting shape, affordinq protection from the sea. The system itself, or an additional outer structure (13), is designed in such a way that the wave front (12) is confronted by a zig-zagging structure (10) which deflects and reflects the waves. The shanks (14,15) of this structure are pref. at least as long as the wavelength. They pref. enclose angles of 90 deg. and can be hinged together.</p> |
