“…Like other islands in Kvarner Bay, the island of Krk has been influenced by large-scale morphogenetic processes driven by the interplay between tectonic activity, rapid sea-level fluctuations and climate change (e.g. Benac and Juračić 1998;Benac et al 2013). An example of geomorphological features influenced by sea-level fluctuation are tidal notches, which have been extensively studied in the Adriatic (e.g.…”

“…An example of geomorphological features influenced by sea-level fluctuation are tidal notches, which have been extensively studied in the Adriatic (e.g. Benac and Juračić 1998;Faivre et al 2011Faivre et al , 2013Furlani et al 2011Furlani et al , 2014Stiros and Moschas 2012;Benac et al 2013). At smaller spatiotemporal scales, there are observations of beach and cliff erosion due to interactions between natural factors, such as waves, wind, storm surges, and strong rainfall events causing torrential flows, and manmade changes.…”

The aim of this study was to examine the capability of structure-from-motion photogrammetry in defining the geometry of cliffs and undercuts in rocks of complex geomorphology. A case site was chosen along pocket beaches near the village of Stara Baška on the Adriatic Sea island of Krk, Gulf of Kvarner, Croatia, where cliff erosion of 5 m in breccias was identified by comparison of aerial photographs from 1960 and 2004. The 3D point cloud was derived from approx. 800 photos taken on 9 January 2014 by a single camera from various elevations and angles, and processed using the online software ReCap (Autodesk). Data acquisition was found to be quick and the method easy to implement. The difference between the georeferenced 3D cloud points and an RTK-GPS survey was 7 cm, i.e. within the limits of RTK-GPS precision. Quantifying the spatial variation in undercut geometries revealed that the deepest and largest (17 m 3 ) undercut was in the south-eastern sector of the beach. Reconstructing the detailed geomorphology of this 3.8-m-deep undercut convincingly demonstrates the high efficiency of the method. Such assessments of spatiotemporal changes in undercut and overhang volumes can prove useful for evaluations of cliff erosion risk. Coupled with the low cost and relatively simple application, this is evidently an attractive technique for meaningful geotechnical and coastal engineering monitoring in the future on the island of Krk and, for that matter, also on other Adriatic islands and in similar settings worldwide.

“…Therefore, dry valleys, palaeohydrographic networks and their relations with other karst forms can be used in the reconstruction of karst evolution under various conditions and in different areas (e.g. Day, 1983a,b;Smart and Statham, 1984;Sauro, 1991;Nicod, 1997;Quinif, 1999;Phillips et al, 2004;Monod et al, 2006;Gioia et al, 2011;De Waele et al, 2012;Benac et al, 2013;Haryono, 2013). The significance of the tectonic uplifting of karstified terrain in this process has often been emphasised.…”

Abstract: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.
