    • The influence of wave direction on the morphological response of a double sandbar system 

      Thiebot, Jerome; Idier, Deborah; Garnier, Roland; Falqués Serra, Albert; Ruessink, B.G. (2012-01-01)
      Article
      Accés restringit per política de l'editorial
      Nearshore sandbars are often characterized by three-dimensional bed patterns. To analyze the influence of wave direction on the morphological response of a double sandbar system, this paper uses the 2DH nonlinear surf zone ...

      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 ...
