      Van den Berg, Niels; Falqués Serra, Albert; Ribas Prats, Francesca (2011-10)
      Article
      Accés obert
      A nonlinear numerical model for large-scale dynamics of shoreline and nearshore bathymetry under wave action is applied to investigate the long-term evolution of a rectilinear coast dominated by high angle wave incidence, ...

    • Modeling large scale shoreline sand waves under oblique wave incidence 

      Van den Berg, Niels; Falqués Serra, Albert; Ribas Prats, Francesca (American Geophysical Union (AGU), 2012)
      Article
      Accés obert

    • Modeling shoreline sand waves on the coasts of Namibia and Angola 

      Ribas Prats, Francesca; Falqués Serra, Albert; Van den Berg, Niels; Caballeria Suriñach, Miquel (2013-09)
      Article
      Accés obert
      The southwestern (SW) coast of Africa (Namibia and Angola) features long sandy beaches and a wave climate dominated by energetic swells from the Southsouthwest (SSW), therefore approaching the coast with a very high ...

    • Modelling high angle wave instability and the generation of large scale shoreline sand waves 

      Van den Berg, Niels; Falqués Serra, Albert; Ribas Prats, Francesca (2010-05-07)
      Text en actes de congrés
      Accés obert

    • Modelling shoreline sand waves: application to the coast of Namibia 

      Falqués Serra, Albert; Van den Berg, Niels; Ribas Prats, Francesca; Caballeria Suriñach, Miquel (2011)
      Comunicació de congrés
      Accés restringit per política de l'editorial
      The SW coast of Africa (Namibia and part of Angola) features very long sandy beaches and a wave climate dominated by energetic swells from the SSW, therefore approaching the coast with a very high obliquity. Satellite ...

    • Modelling the dynamics of large scale shoreline sand waves 

      Van den Berg, Niels (Universitat Politècnica de Catalunya, 2012-05-11)
      Tesi
      Accés obert
      Shoreline sand waves are shoreline undulations with a length scale of several kilometres and a time scale of years to decades. They occur on many coasts, migrating in the direction of the dominant littoral drift and they ...

    • On the mechanism of wavelength selection of self-organized shoreline sand waves 

      Van den Berg, Niels; Falqués Serra, Albert; Ribas Prats, Francesca; Caballeria Suriñach, Miquel (American Geophysical Union (AGU), 2014-03-26)
      Article
      Accés obert
      Sandy shorelines exposed to very oblique wave incidence can be unstable and develop self-organized shoreline sand waves. Different types of models predict the formation of these sand waves with an initially dominant ...

    • Potential instabilities of Catalan coastline induced by high-angle waves 

      Caballeria Suriñach, Miquel; Falqués Serra, Albert; Van den Berg, Niels (2011)
      Comunicació de congrés
      Accés restringit per política de l'editorial
      The relatively long sandy beaches of El Maresme, and the bimodal wave climate of the Catalan coast, with dominant E-ENE and SSW waves that leads to high angle of incidence, propitiate good conditions for high angle of wave ...

    • Self-organized morphological patterns in coastal dynamics 

      Falqués Serra, Albert; Calvete Manrique, Daniel; Van den Berg, Niels; Ribas Prats, Francesca; Fernández Mora, Ma. Àngels; Caballeria Suriñach, Miquel (Universitat Politècnica de Catalunya. Escola Tècnica Superior d'Enginyers de Camins Canals i Ports de Barcelona, 2011-11-16)
      Comunicació de congrés
      Accés obert
      the meaning and significance of self-organization processes in coastal morphodynamics is presented. Two types of coastal self-organized patterns are discussed: crescentic bars in the surf zone and free shoreline sand waves ...

    • Shoreline sand waves along the catalan coast 

      Falqués Serra, Albert; Caballeria Suriñach, Miquel; Ribas Prats, Francesca; Van den Berg, Niels (2013)
      Comunicació de congrés
      Accés obert
      The beach of Calella, north of Barcelona, in the Catalan coast, features a series of shoreline sand waves with wavelengths ranging from 700 to 1400 m that match with similar undulations in the -5 m bathymetric line. ...

    • Shoreline sand waves and beach nourishments 

      Van den Berg, Niels; Falqués Serra, Albert; Ribas Prats, Francesca (Coastal Engineering Research Council, 2010)
      Text en actes de congrés
      Accés obert
      The effects of the feedback between the changing coastal morphology and the wavefield on the generation and propagation of large scale (O(1-10 km)) shoreline sand waves is examined with a quasi-2D morphodynamic ...

    • The role of cross-shore profile dynamics on shoreline instability due to high-angle waves 

      Falqués Serra, Albert; Van den Berg, Niels; Calvete Manrique, Daniel (2008)
      Comunicació de congrés
      Accés restringit per política de l'editorial
      If the wave climate is dominated by a wave approach in deep water that is very oblique with respect to the shoreline, the littoral drift may render the rectilinear trend of the shoreline unstable. This instability causes ...

    • What determines the wavelength of self-organized shoreline sand waves?

      Comunicació de congrés
      Accés obert
      Shoreline undulations extending into the bathymetric contours with a length scale larger than that of the rhythmic surf zone bars are referred to as shoreline sand waves. Many observed undulations along sandy coasts display ...
