  • 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.

  • and the evolving morphology (that is, self-organization) enforces the development of coupling patterns. The AA. therefore introduce a novel mechanism that blurs the distinction between self-organization and template mechanisms. This mechanism may also be extended
