Description

Abstract. The total length of the Black Sea coastline is over 4 400 km and belongs to 6 states: Bulgaria, Turkey, Georgia, Russian Federation, Ukraine and Romania. The proposed zoning of the Black Sea coastal zone evidences 17 main sections characterised by different geology and morphology, as well as specific littoral water circulation, sediment drift systems and sedimentary budget. These zones belong to three main morphodynamic categories: (1) low, accumulative coasts mostly related to the rivers mouth zones (mainly sandy complex barrier beaches with strong longshore sediment drift systems); (2) Erosive coasts within lowstanding plateaux and plains, with active cliffs with very narrow beaches in front of the cliffs; (3) Mountainous coasts, with cliffs, marine terraces, land slides, sometimes with sandy or gravely beaches. An overview of the coastal erosion in the Black Sea and of factors controlling these erosional process is given. The threats to the coastal zone generated by global changes and anthropogenic pressure are analysed. The most vulnerable sections of the Black Sea coastal zone exposed to environmental risks are presented and analysed.
