Tesis doctoral de Elena Ojeda Casillas
This thesis deepens the knowledge on the morphodynamics of anthropogenic impacted beaches focusing at spatial scales of tens of metres to kilometres and time scales ranging from several hours (e.G. Response to a storm event) to interannual (e.G. Interannual migration pattern). With this purpose two stretches of coast subject to human interventions but with different characteristics were monitored: three of the artificial embayed beaches of the coast of barcelona city (mediterranean sea, spain), and the long sandy beach of noordwijk (north sea, the netherlands). Both beaches were monitored through an argus video system that comprises five video cameras pointing at the beaches. At noordwijk the cameras are located at about 60 m height and at barcelona at approximately 142 m height. the previous scientific knowledge of the morphodynamics of both regions prior to this study was quite different. While the dynamics of barcelona city beaches was poorly known, the nearshore dynamics of noordwijk has been widely studied. For this reason, the first two chapters of the thesis are dedicated to investigate the morphodynamics of barcelona city beaches, and the following two chapters analyze the response of the nearshore after artificial nourishments at barcelona and noordwijk beaches. Chapters 2 and 3 focus in the shoreline and sandbar dynamics of barcelona city beaches, investigating the nearshore response to storm events, the behaviour of the emerged beach area, the three-dimensional changes in the sandbar configuration and the beach rotation at different time-scales. The following two chapters analyze the morphodynamic response of the nearshore to a beach nourishment carried out at barcelona (chapter 4) and a shoreface nourishment accomplished at noordwijk (chapter 5).
