The Recent Geomorphological Processes in the Area of the Rijeka Bay
Čedomir Benac
Sažetak
In the paper has been analysed arecent geomorphological processes in coastal area of Rijeka Bay (Northern Adriatic). The rapidly sea-level rise started from the end of last Würm glacial age. Therefore the erosion base, the relief energy and the intensity of the erosion and the sedimentation have chaged. The lower parts of the numerious valleys have been submerged. The rapid sedimentation began near the Rječina River mouth. In the last milleniums there is expressive work of abrasion and bioerosion. The initial forms of the abrasion platform has been formed. The process abrasion is very selective. It primarily depends of geological structure and hardness of rocks in the littoral zone as well as of the local maritime conditions. A relief of the greatest part of the coastal area of Rijeka Bay depends primarily of local srtuctural and tectonic rock fabric. In littoral zone of carbonate composition we have been seen processes of bioerosion. The processes of bioerosion are apparently in the carbonate rocks of littoral zone. The gullies are active on slopes of Učka Mountain and island Cres, but this are mainly fossil in northern coastland and island Krk.
