Dynamics of the rhythmic morphology on the low-energy Trabucador beach (Ebro delta)
(Consejo Superior de Investigaciones Científicas (CSIC), 2019)
Text en actes de congrés
Accés obertObservations of rhythmic morphology along the Trabucador beach are contrasted with two numerical models to unravel the mechanisms of their formation. The Trabucador is a long narrow barrier at the SW side of the Ebro ... -
Effect of large angles of wave incidence on beach nourishments
(2009)
Text en actes de congrés
Accés restringit per política de l'editorialThe aim of this study is to investigate the effect of instability on beach nourishments. The main objective is finding out how the nourishment of a particular beach must be designed to i) optimize its useful lifetime and ... -
Effect of surface rollers on the formation crescentic bars
(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 ... -
Effect of surface rollers on the formation of crescentic bars: large angles of incidence
(2012)
Comunicació de congrés
Accés obertThe formation of crescentic bars is examined using a morphodynamic model based in linear stability analysis. The effect of surface rollers for off-normal wave conditions is examined. The effect of the rollers is to increase ... -
Emerging crescentic patterns in modelled double sandbar systems under normally incident waves
(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 and destruction of shoreline sand waves: observations and modelling
(2017)
Text en actes de congrés
Accés obert -
Formation events of shoreline sand waves on a gravel beach
(2018-05-04)
Article
Accés obertKilometric-scale shoreline sand waves (KSSW) have been observed in the north-east flank of the Dungeness Cuspate Foreland (southeastern coast of the UK). They consist of two bumps separated by embayments with a 350–450-m ... -
Formation mechanisms for self-organized kilometer-scale shoreline sand waves
(2017-05-16)
Article
Accés obertThe feedbacks between morphology and waves through sediment transport are investigated as a source of kilometer-scale shoreline sand waves. In particular, the observed sand waves along Srd. Holmslands Tange, Denmark, are ... -
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 ... -
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 ... -
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 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. ...
