The work focuses on backbarrier marsh genesis and early evolution in Culatra, aiming to: a) identify present-day marsh zonation and recent sedimentation; b) assess long-term backbarrier marsh dynamics (horizontal and vertical growth and sediment composition); and c) identify the main controls, phases and related timescales.

We employ an updated and validated version of Duna, a simplified 1D morphodynamic model, to assess the impacts of dune shape (height and slope), beach width, vegetation cover and wind angles to wind flow and topographic changes on the dune and to extract draw generalized growth patterns.

We explore the longshore variability of the morphological features, plant community distribution and accumulation patterns of a dune segment. Integrated results from different timescales document strong differences, with two distinct dune configurations or ecogeomorphic states identified in close proximity.

Short-term beach morphodynamics are typically modelled solely through storm-induced erosion, disregarding post-storm recovery, even though the full cycle of beach profile response is critical for even longer temporal scales. We simulate morphodynamic changes from the incidence and post-storm recovery of Faro Beach from the Emma storm.

Novel methodology, based on identifying barrier states and related threshold crossings and on reconstructing the resilience trajectories of barrier islands, thus expressing the spatiotemporal changes in resilience topography (resilience dimensions and barrier stable states), in response to external conditions and internal barrier organisation

Resilience has been used over a wide range of scientific fields and often ambiguously, causing confusion and misconceptions, even within the same scientific discipline. Starting by providing clarifications and definitions of the main terminology and key principles of ecological resilience theory, we pass on to expressing them through geomorphic dimensions of barrier islands.
