Beaches: Black Sea Beaches Retreat [% of surface loss]

  • Title: Beaches: Black Sea Beaches Retreat [% of surface loss]
  • Abstract:

    A complete database of Black Sea beaches have been digitalized in Google Earth Pro Application. The dataset are in shapefile format and contain an attribute table with a brief description of the surrounding environment (geometry of the beach, information on images used, presence or absence of wave and/or river, and an appreciation of the sediment size) and percentages of beach's surface loss estimated by the lowest and the highest retreat prediction for three level rise scenarios (0.5 m, 0.82 m and 1 m).
    Beach erosion vulnerability has been assessed by combining Black Sea beaches geodatabase with coastal retreat prediction induced by sea level rise scenarios.
    Coastal retreat was estimated using an ensemble of 6 analytical (Edelman, 1972; Brunn, 1988; Dean, 1991) and numerical (Larson and Kraus, 1989; Leont’yev, 1996; Roelvink (Xbeach), 2010) models for a vast range of environmental condition, to better reflect the entire Black Sea basin.

    The map shows the maximum beach’s surface loss in percentage induced by a sea level rise of 0.5 m (max. retreat prediction of 21.4 m).
