      Joint intrinsic and extrinsic calibration from a single snapshot is a common requirement in coastal monitoring practice. This work analyzes the influence of different aspects, such as the distribution of Ground Control ...
    • Characteristics and dynamics of crescentic bar events at Castelldefels beach 

      Swart, Rinse Leendert de; Ribas Prats, Francesca; Simarro, Gonzalo; Guillén Aranda, Jorge (Consejo Superior de Investigaciones Científicas (CSIC), 2019)
      Conference report
      Open Access
      Crescentic sand bars have been studied intensively in the last decades, resulting in good knowledge of some of their characteristics, but the processes behind their formation and destruction are not yet clear. This study ...
    • Characteristics and dynamics of crescentic bar events in an open, tideless beach 

      Swart, Rinse Leendert de; Ribas Prats, Francesca; Ruessink, Gerben; Simarro, Gonzalo; Guillén Aranda, Jorge (2017)
      Conference report
      Open Access
      Crescentic bar events at Castelldefels beach (NW Mediterranean) have been characterised using a 4.25 years dataset (October 2010-December 2014) of time-exposure video images. Crescentic bars are observed during 41% of ...
    • Characterization of bottom sediment resuspension events observed in a micro-tidal bay 

      Grifoll Colls, Manel; Cerralbo Peñarroya, Pablo; Guillén Aranda, Jorge; Espino Infantes, Manuel; Boye Hansen, Lars; Sánchez-Arcilla Conejo, Agustín (2019-03)
      Article
      Open Access
      In this study we investigate the variability in near-bottom turbidity in Alfacs Bay (in the northwestern Mediterranean Sea). The bay is characterized by a micro-tidal environment and seiching activity that may lead to flow ...
    • Dynamics of single-barred embayed beaches 

      Ojeda Casillas, Elena; Guillén Aranda, Jorge; Ribas Prats, Francesca (2011-02-15)
      Article
      Open Access
      The dynamics of single submerged sandbars of two artificial embayed beaches (La Barceloneta and Bogatell, Barcelona, NW Mediterranean) has been studied with a video-recorded data set of 4.3 years. The alongshore-averaged ...
    • Morphological changes, beach inundation and overwash caused by an extreme storm on a low-lying embayed beach bounded by a dune system (NW Mediterranean) 

      Duran, Ruth; Guillén Aranda, Jorge; Ruiz García, Antonio; Jiménez Quintana, José Antonio; Sagrista, Enric (2016-12)
      Article
      Open Access
      The geomorphological evolution of a low-lying, micro-tidal sandy beach in the western Mediterranean, Pals beach, was characterized using airborne Light Detection and Ranging (LiDAR) data. Data were collected in prior to ...
    • Sediment transport and dispersal in the nearshore of “flash-flood” rivers 

      Grifoll Colls, Manel; Gracia Garcia, Vicente; Guillén Aranda, Jorge; Espino Infantes, Manuel; Sánchez-Arcilla Conejo, Agustín (2014)
      Conference lecture
      Open Access
      River sediment dispersal on the near-shore of “flash-flood” rivers is investigated using a coupled wave-current-sediment transport model. Besòs and Llobregat rivers (short and mountainous rivers in NW Mediterranean Sea, ...
    • The morphodynamic responses of artificial embayed beaches to storm events 

      Ojeda Casillas, Elena; Guillén Aranda, Jorge; Ribas Prats, Francesca (2010)
      Article
      Open Access
      The morphological changes caused by storm events in two Barcelona beaches were recorded using video monitoring techniques during the period 2001–2006. Changes in shoreline position and configuration and submerged bar ...
