Sažetak
The paper describes the influence of the marine erosion and slope instabilities on cliff retreat in the coast near Stara Baška settlement on Krk Island (northeastern channel part of the Adriatic Sea). The bedrock is occasionally covered by breccia from Quaternary period. The coast around Stara Baška is exposed to wave attack and thereby to marine erosion. By comparison of orthophoto maps from 1966 and 2004, the significant coastal retreat was determined. This phenomenon has been a fundamental trigger off different instability phenomena. The type of instabilities is a consequence of the local geological fabric and rock mass resistivity marine erosion. In the investigated area, rock falls and slumps prevail in cliffs formed in breccia. Extremely high tides with the combination of strong waves from southern direction have a significant influence on the coastal erosion. This is an indicator of the possible higher hazard degree caused by the sea-level rise.
