A model for grain-size sorting over tidal sand ridges
Walgreen, M; de Swart, Huib E.; Calvete Manrique, Daniel (2004-07)
Article
Accés restringit per política de l'editorialA model was developed and analyzed to quantify the effect of graded sediment on the formation of tidal sand ridges. Field data reveal coarse (fine) sediment at the crests (in the troughs), but often phase shifts between ... -
Dynamics of shoreface-connected and inactive sand ridges on a shelf, Part 2: The role of sea level rise and associated changes in shelf geometry
Nnafie, Abdel; de Swart, Huib E.; Calvete Manrique, Daniel; Garnier, Roland Charles (2015-08)
Article
Accés obertMany inner continental shelves are characterized by the presence of large rhythmic bedforms, such as shoreface-connected ridges and the more offshore located sand ridges, which have heights of several meters and are spaced ... -
Effect of surface rollers on the formation crescentic bars
Calvete Manrique, Daniel; Ribas Prats, Francesca; de Swart, Huib E.; Falqués Serra, Albert (2011)
Comunicació de congrés
Accés restringit per política de l'editorialThe effect of surface rollers on the formation of crescentic bars/rip channel systems is examined with a morphodynamic model. A linear stability analysis is applied to find the fastest growing bottom patterns that develop ... -
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 obertDouble 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 ... -
Formation of shoreface-connected sand ridges: effects of rigid-lid approach, quasi-steady approach and wave-topography feedbacks
Nnafie, Abdel; de Swart, Huib E.; Garnier, Roland; Calvete Manrique, Daniel (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 ... -
Long-term morphodynamics of a coupled shelf-shoreline system forced by waves and tides, a model approach
Nnafie, Abdel; de Swart, Huib E.; Falqués Serra, Albert; Calvete Manrique, Daniel (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 ... -
Modelling the formation of transverse sand bars: application to Duck beach, USA
Ribas Prats, Francesca; de Swart, Huib E.; Calvete Manrique, Daniel; Falqués Serra, Albert (2011)
Text en actes de congrés
Accés obertA morphodynamic model has been applied to explain the formation of transverse sand bars at Duck beach, USA. The model describes the feedback between waves, rollers, depth-averaged currents and bed evolution, so that ... -
Non-linear response of shoreface-connected sand ridges
de Swart, Huib E.; Calvete Manrique, Daniel (2003-10)
Article
Accés restringit per política de l'editorialA non-linear morphodynamic model of a microtidal coastal shelf is used to study the response of shoreface-connected sand ridges and the net sand balance of the shelf to large-scale interventions. The model describes the ... -
Nonlinear modelling of shoreface-connected ridges; impact of grain sorting and interventions
de Swart, Huib E.; Walgreen, M; Calvete Manrique, Daniel; Vis-Star, N C (2008-01)
Article
Accés restringit per política de l'editorialThe evolution of shoreface-connected sand ridges on micro-tidal inner shelves and the variations in the mean grain size over these ridges are investigated with process-based models. A review of previous studies is presented, ... -
On the physics behind coastal morphodynamic patterns
Ribas Prats, Francesca; Falqués Serra, Albert; de Swart, Huib E.; Dodd, Nicholas; Garnier, Roland Charles; Calvete Manrique, Daniel (2016)
Text en actes de congrés
Accés obert -
Onshore sandbar migration in the surf zone: new insights into the wave-induced sediment transport mechanisms
Fernández Mora, María de los Ángeles; Calvete Manrique, Daniel; Falqués Serra, Albert; de Swart, Huib E. (2015-04-28)
Article
Accés obertWe present a novel process-based morphodynamic model, which includes transport processes due to both velocity and acceleration skewness and a new formulation for intrawave motions, that successfully simulates observations ... -
Understanding coastal morphodynamic patterns from depth-averaged sediment concentration
Ribas Prats, Francesca; Falqués Serra, Albert; de Swart, Huib E.; Dodd, Nicholas; Garnier, Roland Charles; Calvete Manrique, Daniel (2015)
Article
Accés obertThis review highlights the important role of the depth-averaged sediment concentration (DASC) to understand the formation of a number of coastal morphodynamic features that have an alongshore rhythmic pattern: beach ...
