Coastal erosion Slovenia


The coastline of Slovenia is 46 km long. Flysch rock (alternating marls, siltstones and sandstones) stretches along the entire Slovenian coast and along parts of the coast of Croatia and Montenegro. Badlands are a common erosional landscape on the flysch, and cliffed coasts evolve under destructive wave impact and subaerial weathering and erosional processes. The majority of the cliffs are up to 80 m in height. At some locations there are gravel/pebble beaches (1). Cliff erosion rate is 1-2 cm/year (2).

Adaptation strategies

Some 82% of the Slovenian coastline is manmade. Some urbanized coastal areas have historical protection ranging from seawalls and submerged breakwaters to rock dikes. These structures have been effective for centuries and the erosion of the Slovenian coastline is generally well controlled and properly managed (3).
