The morphological changes caused by storm events in two Barcelona beacheswere recorded using video monitoring techniques during the period 2001–2006.Changes in shoreline position and configuration and submerged bar positionand shape were analyzed during the 25 major storm events that occurredduring the study period. Beach responses to storms were grouped into threecategories: shoreline advance or retreat (including rotation), sandbarmigration and/or configuration change (linear or crescentic shape) andformation of megacusps. This work provides examples of the differentialadaptation of both beaches to the same storm and of some unexpectedmorphological responses of both beaches. The response of the beach to stormevents is not straightforward because wave conditions are not the onlyrelevant parameter to be considered. In particular, in such embayed beachesit is crucial to take into account their specific morphodynamicconfiguration prior to the storm.
