  • A morphodynamic mechanism for transverse bars in the nearshore
    Caballeria, Miquel; Falqués, Albert; Coco, G.; Huntley, D.A. (American Society of Civil Engineers, 2001)
    Sand bars which are normal to the coastline have been described on sandy beaches Irom low to moderate wave energy (Niedoroda and Tanner, 1979; Konicki and Holman, 2000). A generating mechanism lor such bars is here proposed ...
  • A subcritical instability of wave-driven alongshore currents
    Dodd, Nick; Iranzo, Vicente; Caballeria, Miquel (American Geophyisical Union, 2004)
    The development of shear instabilities of a wave-driven alongshore current is investigated. In particular, we use weakly nonlinear theory to investigate the possibility that such instabilities, which have been observed ...
  • Frontshear and backshear instabilities of the mean longshore current
    Baquerizo, Asunción; Caballeria, Miquel; Losada, Miguel A.; Falqués, Albert (American Geophysical Union, 2001)
    An analytical model based on Bowen and Holman [1989] is used to prove the existence of instabilities due to the presence of a second extremum of the background vorticity at the front side of the longshore current. The ...
  • Generation and nonlinear evolution of shore-oblique/transverse sand bars
    Garnier, R.; Calvete, D.; Falqués, Albert; Caballeria, Miquel (Cambridge University Press, 2006)
    The coupling between topography, waves and currents in the surf zone may selforganize to produce the formation of shore-transverse or shore-oblique sand bars on an otherwise alongshore uniform beach. In the absence of ...
  • Modeling shoreline sand waves on the coasts of Namibia and Angola
    Ribas Prats, Francesca; Falqués, Albert; Van den Berg, Niels; Caballeria, Miquel (Elsevier, 2013)
    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 obliquity. ...
  • On themechanism of wavelength selection of self-organized shoreline sand waves
    Van den Berg, Niels; Falqués, Albert; Ribas Prats, Francesca; Caballeria, Miquel (Wiley, 2014)
    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 ...
  • Self-organization mechanisms for the formation on nearshore crescentic and transverse sand bars
    Caballeria, Miquel; Coco, G.; Falqués, Albert; Huntley, D.A. (Cambridge University Press, 2002)
    The formation and development of transverse and crescentic sand bars in the coastal marine environment has been investigated by means of a nonlinear numerical model based on the shallow-water equations and on a simpli ...
  • Video observations of crescentic sandbar formation and modelling implications
    Coco, G.; Ruessink, B.G.; Van Enckevort, I.M.J.; Caballeria, Miquel; Falqués, Albert; Holman, R.A.; Plant, N.G.; Turner, I.L. (World Scientific, 2005)
    The development of surf zonc crescentic sandbars has beeo analyzed using video observations al lhrce sites: Duck (USA), Gold Coast (Australia). and NoordwiJk (The Netherlands). Video observations indicate the developmenl ...
  • What determines the wavelength of self-organized shoreline sand waves?
    Falqués, Albert; Van den Berg, Niels; Ribas Prats, Francesca; Caballeria, Miquel (2012)
    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 ...
