Formation of shoreface-connected sand ridges: effects of rigid-lid approach, quasi-steady approach and wave-topography feedbacks
(2011)
Comunicació de congrés
Accés restringit per política de l'editorialThe initial- and long-term evolution of shoreface-connected sand ridges (sfcr) is investigated with a new nonlinear model (MORFO56) that employs finite difference methods, rather than spectral methods. MORFO56 uses ... -

Generation and nonlinear evolution os shore-oblique/transverse sand bars
(2006-11)
Article
Accés obertThe coupling between topography, waves and currents in the surf zone may self-organize to produce the formation of shore-transverse or shore-oblique sand bars on an otherwise alongshore uniform beach. In the absence of ... -
Growth of large-scale bed forms due to storm-driven and tidal currents: a model approach
(2002-12)
Article
Accés restringit per política de l'editorial -
Instability of time-dependent wind-driven ocean gyres
(2002-10)
Article
Accés obertThe wind-driven ocean circulation at midlatitudes is susceptible to several types of instabilities. One of the simplest models of these flows is the quasigeostrophic barotropic potential vorticity equation in an idealized ... -
Large-scale dynamics of sandy coastlines: diffusivity and instability
(2005-03)
Article
Accés obertThe dynamics of small-amplitude perturbations of an otherwise rectilinear coastline due to the wave-driven alongshore sediment transport is examined at large time and length scales (years and kilometers). A linear stability ... -
Linear evolution of a shoreface nourishment
(2007-05)
Article
Accés restringit per política de l'editorialThe morphological evolution of a shoreface nourishment is investigated by interpreting the nourishment as a linear perturbation of the natural system. The nourishment is projected onto the subset of linear eigenmodes with ... -
Long-term morphodynamics of a coupled shelf-shoreline system forced by waves and tides, a model approach
(American Geophysical Union (AGU), 2021-12)
Article
Accés obertSand ridges, with length scales of several km, are prominent features of the seafloor landscape of many sandy continental shelves. Knowledge about the extent to which these ridges influence the large-scale (i.e., decadal ... -
Mechanisms controlling crescentic bar amplitude
(2010-04-15)
Article
Accés obertThe formation of crescentic bars from self-organization of an initially straight shore-parallel bar for shore-normal incident waves is simulated with a two-dimensional horizontal morphodynamical model. The aim is to ... -
Modeling and analyzing observed transverse sand bars in the surf zone
(American Geophysical Union (AGU), 2012-04-25)
Article
Accés obertA 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 ... -
Modeling the response of shoreface-connected sand ridges to sand extraction on an inner shelf
(2014-05-01)
Article
Accés restringit per política de l'editorialShoreface-connected sand ridges are rhythmic bedforms that occur on many storm-dominated inner shelves. The ridges span several kilometers, are a few meters high, and they evolve on a timescale of centuries. A process-based ... -
Modeling waves, currents and sandbars on natural beaches: The effect of surface rollers
(2011-10)
Article
Accés obertA morphodynamic model has been extended to gain more fundamental knowledge about the formation of nearshore sand bars. The model describes feedbacks between waves, rollers, depth-averaged currents and bed evolution, so ... -
Modelling bedforms on the continental shelf
(Springer International Publishing, 2017)
Capítol de llibre
Accés restringit per política de l'editorialA number of morphodynamic models have been developed to simulate the dynamics of large-scale bedform patterns on the continental shelf. Most of the models are based on linear stability analysis and, therefore, only ... -

Modelling the formation and the long-term behavior of rip channel systems from the deformation of a longshore bar
(2008-07)
Article
Accés obertA nonlinear numerical model based on a wave- and depth-averaged shallow water equation solver with wave driver, sediment transport, and bed updating is used to investigate the long-term evolution of rip channel systems ... -
Modelling the formation and the nonlinear evolution of crescentic bars of the Aquitanian coast
(2008-07)
Article
Accés restringit per política de l'editorialCrescentic bars emerge as free instabilities of the coupling between topography and water motion. Their long term behaviour will be studied in the real case of the French Aquitaine beaches by using the 2DH numerical model ... -
Modelling the formation of shoreface-connected sand ridges on storm-dominated inner shelves
(2001-08)
Article
Accés obertA morphodynamic model is developed and analysed to gain fundamental understanding of the basic physical mechanisms responsible for the characteristics of shorefaceconnected sand ridges observed in some coastal seas. These ... -
