Optical satellite imagery can now infer such datasets globally, but sometimes with large uncertainties, poor spatial resolution, thus debatable outcomes. Here we validate analyse satellite-derived-shoreline positions (1984–2021) along Atlantic coast Europe using a moving-averaged approach based on coastline characteristics, indicating conservative uncertainties long-term trends around 0.4 m/year potential bias towards accretion. We show that west-facing open coasts are more prone erosion, whereas relatively closed favor accretion, although most computed fall within range uncertainty. Interannual variability influenced by regionally dominant atmospheric climate indices. Quasi-straight coastlines typically strongest alongshore-uniform links, while embayed coastlines, especially those not exposed wave climate, weaker variable correlation Our results provide continuum between previous local-scale studies, emphasizing necessity further reduce satellite-derived trend uncertainties. They also call for applications relevant averaging inclusion coastal setting parameters unravel forcing-response spectrum shorelines globally.

Sandy coastlines are very dynamic spaces affected by a variety of natural and human factors. In Central Chile, changes in oceanographic wave conditions, modes inter-annual climate variability such as El Niño Southern Oscillation (ENSO), extreme events earthquakes tsunamis condition the beach morphology. At same time, direct actions alter arrival sediments to coast their alongshore distribution. Despite relevance beaches for this coastal region interesting relationship morphology has with aforementioned factors, there is lack robust morphological datasets provide deep characterization understanding dynamism Chilean coast. Based on information provided satellite-derived shorelines (SDSs) defined using SHOREX algorithm, paper characterizes Playa Grande Cartagena Bay (Central Chile) during period 1985–2019. The shoreline position data analyzed context changing transforming elements, allowing better according multiple drivers. While some these or storms, have punctual character, patterns vary at different time scales, from seasonal multi-annual, linked phases ENSO. Its effects translated into erosion accretion conditioned orientation while influenced availability sediment system. According that, conceptual model redistribution proposed. work proves high utility that systematic analysis multi-decadal SDS obtained images acquired optical Landsat Sentinel-2 offer monitoring dynamism.

Abstract Contemporary shoreline change is driven by a complex combination of factors, and as such often highly variable along the coast. While differences in beach morphology can explain some variability change, geological constraints imposed coastal geology are overlooked.

The morphological responses of two mesotidal beaches located in different coastal settings (embayed and open sandy beaches) on the northwestern Iberian coast were monitored during winter 2018/19. offshore wave time series analysis is related to high-resolution topo-bathymetric measurements explore spatial-temporal variability at monthly seasonal scales. Both locations are subjected North Atlantic climate which exhibits a pronounced seasonality. Throughout last decade (2010–2020), significant heights reached values up Hs~9 m winters Hs~6 summers. On average, approximately 12 storms occurred annually this region. results clearly reveal divergent sediment transport behaviors upper beach intertidal zone for each location. In embayed (Patos), nearshore governed by cross-shore processes between berm submerged sandbar. contrast, (Mira) showed dynamic exchanges three-dimensional morphologies alternating accumulation erosion zones. Overall, both exhibited an erosional trend after winter, particularly concerning subaerial volume/shoreline retreat.
