Erosional processes acting on coastal cliffs in the Split urban zone, Croatia

Abstract

The terrestrial laser scanner was used for the first-time assessment of erosional rates of the Duilovo flysch cliff situated along the predominantly carbonate Croatian coast, and to characterize processes involved. Cliff retreat rates ranged between 3 and 18 cm/y and stronger erosion occurs during the cold season due to the slaking process. Cliff erosion detected is a combination of flysch weathering, gravitational instability of degraded material and wave erosion. Understanding of cliff erosion processes in the urban zone is needed for the management purposes in the future.
