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 ... -
How kilometric sandy shoreline undulations correlate with wave and morphology characteristics: preliminary analysis on the Atlantic coast of Africa
(2014-04-01)
Article
Accés obertSandy coasts are characterized by a number of rhythmic patterns like, amongst others, shoreline undulations or sandwaves at a kilometric scale. One hypothesis for their formation is that high angle waves (large incidence ... -

Impact of mean sea-level rise on the long-term evolution of a mega-nourishment
(Springer Nature, 2023-05-15)
Article
Accés obertMean sea-level rise (MSLR) will induce shoreline recession, increasing the stress on coastal systems of high socio-economic and environmental values. Localized mega-nourishments are meant to alleviate erosion problems by ... -
Intertidal finger bars at El Puntal spit, bay of Santander, Spain
(2012)
Comunicació de congrés
Accés obertWe indentify the presence of an intertidal finger bar system in the swell-protected beaches of El Puntal Spit (Bay of Santander, Spain). The Horus video monitoring system allows us to perform a 2 year survey (June 2008- ... -
Km-scale shoreline sand waves
(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 ... -
Km-scale shoreline sand waves in the Western Mediterranean Sea
(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 ... -
Km-scale shoreline sand waves: Numerical modelling and observations
(2014)
Text en actes de congrés
Accés obertKm-scale shoreline sand waves have been studied with a quasi two dimensional model (Q2D-morfo model) and with observations from a populated coastal zone in Yucatán (México) with frequent human interventions. The model ... -
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 and large-scale modeling of mega-nourishments
(2016)
Text en actes de congrés
Accés obertThe Sand Engine, ZM (Zandmotor), is a hook-shaped mega-nourishment (21.5 millions m³) located on the Dutch coast with an alongshore length of 2.4 km and an offshore extension of 1 km. The mega-nourishment project ... -
Long-term evolution of nourished beaches under high angle wave conditions
(2011-10)
Article
Accés obertA 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, ... -
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 ... -
Long-term performance of mega-nourishments: Role of directional wave climate and initial geometry
(MDPI, 2020-12-01)
Article
Accés obertConcentrated mega-nourishments, built as coastal protection measures for decadal time scales,are intended to diffuse, that is to erode and to supply sand to the nearby beaches and dunes by profitingof the natural drivers. ... -
Low energy transverse sand bars at el Trabucador beach, Ebro delta: a preliminary study
(2017)
Text en actes de congrés
Accés obertThe complex rhythmic morphology of the inner side of the Trabucador barrier beach is investigated. This system fea-tures transverse bars along with shoreline undulations. From visual inspection, the typical spacing between ... -
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 ... -
