Barrages et centrales électriques hydrauliques Résumé : The effective dissipation of residual wave energy inside a harbour basin is desirable to improve its tranquillity conditions and the efficiency of port operations. The construction of gentle slopes is frequently unfeasible due to space limitations and physical constraints. Hence, other solutions such as quay walls with a perforated (dissipative) berthing face are used. This research analyses the efficiency to reflection of an innovative type of structure consisting of the superposition of unreinforced concrete blocks, with an original geometry. Physical model tests were conducted at a scale of 1/30 for irregular long-crested waves normal to the quay wall, and the results indicated that reflection can be reduced, particularly for small peak wave periods and large wave heights and water levels. This type of structure was adopted in Portuguese ports, namely in the new multipurpose terminal of the Port of Leixões.
