  • A model for grain-size sorting over tidal sand ridges 

    Walgreen, M; de Swart, Huib E.; Calvete Manrique, Daniel (2004-07)
    Article

    A 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 ...
  • Effect of grain size sorting on the formation of shoreface-connected sand ridges 

    Walgreen, M; Deswart, H E; Calvete Manrique, Daniel (2003-03)
    Article
    Open Access
    Field data of shoreface-connected ridges show persistent spatial variations of mean grain size over the bed forms. In the shore-normal direction, the profiles of bottom topography and mean grain size are approximately 90° ...
  • Modelling the formation of shoreface-connected sand ridges on storm-dominated inner shelves 

    Calvete Manrique, Daniel; Falqués Serra, Albert; Swart, Huib E. de; Walgreen, M (2001-08)
    Article
    Open Access
    A 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 ...
  • 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
    Restricted access - publisher's policy
    The 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, ...
