Operational platform for metocean forecasts in Thermaikos Gulf (Aegean Sea, Gre...
Androulidakis, Yannis; Makris, Christos; Kolovoyiannis, Vassilis; Kombiadou, Katerina; Krestenitis, Yannis; Kartsios, Stergios; Pytharoulis, IoannisThermaikos Gulf, located in the northeastern Mediterranean Sea, faces significant anthropogenic pressures and natural hazards, requiring reliable metocean forecasts for weather, ocean circulation, sea levels, waves, and hazard predictions, including pollutant transport, coastal floods, and freshwater discharges. The Wave4Us operational platform addresses these needs by providing high-resolution and specialised ...
Spectral Unmixing of Coastal Dune Plant Species from Very High Resolution Satel...
Kombiadou, Katerina; Costas, Susana; Gallego-Fernández, Juan Bautista; Yang, Zhicheng; Bon de Sousa, Luísa; Silvestri, SoniaWhile improvements in the spectral and spatial resolution of satellite imagery have opened up new prospects for large-scale environmental monitoring, this potential has remained largely unrealised in dune ecogeomorphology. This is especially true for Mediterranean coastal dunes, where the highly mixed and sparse vegetation requires high resolution satellites and spectral unmixing techniques. To achieve this aim...

Foredune initiation and early development through biophysical interactions
Costas, Susana; Serrão Bon de Sousa, Maria Luísa; Gallego-Fernández, Juan B.; Hesp, Patrick; Kombiadou, KaterinaCoastal dunes result from complex interactions between sand transport, topography and vegetation. However, uncertainty still persists due to limited quantitative analyses, integrating plant distribution and morphologic changes. This study aims to assess the initiation and maintenance of feedback processes by analysing the early development stages of incipient foredunes, combining data on the evolution of the pl...
Ecogeomorphic response of a coastal dune in southern Portugal regulated by extr...
Costas, Susana; Gallego-Fernández, Juan B.; Bon de Sousa, Luísa; Kombiadou, KaterinaCoastal dunes are complex landforms whose morphology results from various interactions between biotic and abiotic factors. Here, we explore the longshore variability of the morphological features, plant community dis-tribution and accumulation patterns of a dune segment (1.4 km-long) located at the downdrift end of a sandy peninsula in the Ria Formosa, Portugal. To understand the main drivers of the observed va...
Exploring controls on coastal dune growth through a simplified model
Kombiadou, Katerina; Costas, Susana; Roelvink, DanoProcess-based morphodynamic models can be useful in understanding coastal dune responses to disturbances, as well as possible evolutionary patterns. To this aim, we employ Duna, a simplified 1D morphodynamic model, to assess the influence of dune morphology (height and slope) on sand transfer and deposition across the dune profile for different beach widths and wind incidence angles through idealized experiment...
Simulating destructive and constructive morphodynamic processes in steep beaches
Kombiadou, Katerina; Costas, Susana; Roelvink, DanoShort-term beach morphodynamics are typically modelled solely through storm-induced erosion, disregarding post-storm recovery. Yet, the full cycle of beach profile response is critical to simulating and understanding morphodynamics over longer temporal scales. The XBeach model is calibrated using topographic profiles from a reflective beach (Faro Beach, in S. Portugal) during and after the incidence of a fierce...
Coastal ridge constructive processes at a multi-decadal scale in Barreta Island...
Herrero, Xabier; Costas, Susana; Kombiadou, KaterinaMultiple ridges across prograding coasts may display variable geometries, commonly expressed through varying elevations. Changes in ridge elevation have been traditionally related to the occurrence of fluctuating progradation rates, which might, in turn, be driven by shifting environmental conditions. Here, we explore the geometry and growth mechanisms of multiple ridges, generated at Barreta Island (Ria Formos...
Rethinking suspended mussel-farming modelling: combining hydrodynamic and bio-e...
Konstantinou, Zoi I.; Kombiadou, KaterinaSuspended mussel-farming using cultivation socks, either in long-line or traditional pole cultivation structures, is a widely spread activity around the world. The sustainability and efficiency of the activity depends on a number of interrelated parameters, as is the natural availability of food, the physical and ecological characteristics of the coastal or marine area and the farmers' choices. The natural para...
Exploring foredune growth capacity in a coarse sandy beach
Costas, Susana; Bon de Sousa, Luísa; Kombiadou, Katerina; Ferreira, Oscar; Plomaritis, Theocharis A.Dunes are key elements of coastal landscapes in almost every latitude. They host high levels of biodiversity and provide important benefits to society; e.g. protection against floods and erosion, or recreation. Coastal dune growth is constrained by intrinsic factors, which are critical when managing dune systems or choosing coastal dune restoration as an alternative green solution for coastal protection. Here, ...
