Coupling mechanisms in double sandbar systems. Part 2 : impact on alongshore variability of inner-bar rip channels

Auteur(s) et Affiliation(s)



Description :
Double sandbar systems are common morphological features along sandy, wave-dominated, micro- to meso-tidal coastlines. Here the AA. use a numerical model to show that the relative importance of self-organization and morphological coupling changes in favour of the latter with an increase in waterdepth variability along the outer-bar crest. Furthermore, they find that the typical alongshore variability in inner-bar rip-channel scale is indicative of a mixture of self-organization and morphological coupling rather than self-organization alone. Morphological coupling may thus be more important to understanding and predicting the evolution of inner-bar rip channels than previously envisaged.
