    Text en actes de congrés
    Accés obert
    Observations of rhythmic morphology along the Trabucador beach are contrasted with two numerical models to unravel the mechanisms of their formation. The Trabucador is a long narrow barrier at the SW side of the Ebro ...
  • Emerging crescentic patterns in modelled double sandbar systems under normally incident waves 

    Coco, Giovanni; Calvete Manrique, Daniel; Ribas Prats, Francesca; de Swart, Huib E.; Falqués Serra, Albert (European Geosciences Union (EGU), 2020-05-06)
    Article
    Accés obert
    Double sandbar systems often characterize the surf zone of wave-dominated beaches and display a variety of poorly explained spatial configurations. Here, we explore the morphodynamic stability of double-barred beaches using ...
  • Erosión en perfiles de playa a distintas escalas 

    Torrent González-Isla, Víctor (Universitat Politècnica de Catalunya, 2009-02)
    Tesina
    Accés obert
    En esta tesina se analiza la dinámica y erosión de un perfil de playa sometido a la acción del oleaje en laboratorios a distintas escalas. Con ello se pretende dar respuesta a la cuestión de cómo los modelos físicos a ...
  • Formation and destruction events of shoreline sand waves 

    Arriaga García, Jaime Alonso; Falqués Serra, Albert; Ribas Prats, Francesca (2017)

  • Modeling and analyzing observed transverse sand bars in the surf zone 

    Ribas Prats, Francesca; Swart, Huib E. de; Calvete Manrique, Daniel; Falqués Serra, Albert (American Geophysical Union (AGU), 2012-04-25)
    Article
    Accés obert
    A morphodynamic model has been applied to explain the characteristics of transverse sandbars observed in the inner surf zone of open beaches. The model describes the feedback between waves, rollers, depth-averaged currents ...
