Accés obert -
Non-linear response of shoreface-connected sand ridges
(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
(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, ... -
Observations and modeling of surf zone transverse finger bars at the Gold Coast, Australia
(2014-08-01)
Article
Accés obertThe occurrence and characteristics of transverse finger bars at Surfers Paradise (Gold Coast, Australia) have been quantified with 4 years of time-exposure video images. These bars are attached to the inner terrace and ... -
Observations of megacusp dynamics and their coupling with crescentic bars at an open, fetch-limited beach
(2022-07-18)
Article
Accés obertAlongshore changes in shorelines along sandy beaches are a result of variations in wave conditions and nearshore morphology, which can cause straight shorelines to develop large-scale (100–1000¿m wavelength) undulations, ... -
Observed alongshore sandbar and shoreline variability at an open, fetch-limited beach
(Coast and Ocean Collective, 2021)
Comunicació de congrés
Accés obertandbars often display an alongshore variable morphology (crescentic bars), which is often mimicked at the shoreline (megacusps). The processes resulting in these patterns are not yet clear and particularly the coupling ... -
Obtaining directional wave characteristics in front of nearshore field sites
(European Geosciences Union (EGU), 2019)

Accés obert -
On beach cusp formation
(2008-02)
Article
Accés obertA system of shallow water equations and a bed evolution equation are used to examine the evolution of perturbations on an erodible, initially plane beach subject to normal wave incidence. Both a permeable (under Darcy's ... -
On the physics behind coastal morphodynamic patterns
(2016)
Text en actes de congrés
Accés obert -
On the predictability of mid-term cross-shore profile evolution
(2013-01-01)
Article
Accés restringit per política de l'editorialThe aim of the present study is to analyse the mid-term beach profile evolution, considering the hypothesis that the alongshore processes can be neglected for the prediction of the mean profile evolution. To this end, a ... -
On the use of linear stability model to characterize the morphological behaviour of a double bar system. Application to Truc Vert beach (France)
(2012-05-22)
Article
Accés restringit per política de l'editorialSandy barred beaches are often characterized by the presence of rhythmic patterns such as crescentic bars. In this article, a linear stability analysis (LSA) model is used to characterize the morphological behaviour of the ... -
Onshore sandbar migration in the surf zone: new insights into the wave-induced sediment transport mechanisms
(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 ... -
Optimal estimations of directional wave conditions for nearshore field studies
(2020-05-15)
Article
Accés obertAccurate directional wave conditions at shallow water are crucial for nearshore field studies and necessary as boundary conditions for morphodynamic models. However, obtaining reliable results for all wave parameters can ... -
Patch behaviour and predictability propierties of modelled finite-amplitude sand ridges on the inner shelf
(University of Thechnology and Agriculture Nicholas Copernicus University, 2008-12)
Article
Accés obertThe long-term evolution of shoreface-connected sand ridges is investigated with a nonlinear spectral model which governs the dynamics of waves, currents, sediment transport and the bed level on the inner shelf. Wave variables ... -
Physics of nearshore bed pattern formation under regular or random waves
(2006-03)
Article
Accés obertWe present an investigation into the growth of nearshore, rhythmic patterns. A comprehensive linear stability model of the surf and shoaling zones is used to examine which type of pattern, transverse or crescentic bar, is ... -
Rhythmic surf zone bars and morphodynamic self-organization
(2008-07)
Article
Accés restringit per política de l'editorialWork undertaken in the EU HUMOR project on morphodynamical modelling, particularly with regard to simulating and understanding rhythmic surf zone bars and related morphodynamic self-organization, is presented. These ... -

(2011-03)
Article
Accés restringit per política de l'editorialPrevious research has shown that a very oblique wave incidence on a coast may render a rectilinear shoreline unstable. Here, we present some further insight into the physics of such instability. The obliqueness of wave ... -
