Lagrangian modelling reveals sediment pathways at evolving coasts.

ABSTRACT: Coastal regions face increasing pressure from climate change, sea-level rise, and growing coastal populations. This "coastal squeeze" threatens both the systems' sustainability and their ecosystem services. Coastal changes depend on the distribution of sediment throughout the system, which evolves continuously through complex transport processes. While we can quantify net morphological changes, this alone provides incomplete understanding of coastal evolution as similar morphological states can result from vastly different sediment movement patterns. Coastline perturbations-deviations from straight coastlines ranging from beach cusps to headlands, deltas, and artificial nourishments-exemplify this challenge. Although their diffusive morphological evolution is well understood, we have limit
