The adaptive capacity is defined as the number of potential irrigation day per year. A potential irrigation day is considered to be a day when the actual stream flow is above the environmental water requirement. The latter was estimated by calculating 80% of the 10-year average stream flow for each respective day (Hoekstra et al., 2011).
Red indicates a decreasing number of potential irrigation days per year (decreasing adaptive capacity) and green indicates an increasing number of potential irrigation days per year (increasing adaptive capacity).
Maximum beach retreat (in percentage of the maximum beach width) predicted by the model ensemble for the Black Sea beaches under a 0.5 m SLR (coastal retreat estimated to 21.4 m.).
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).
