“…Interestingly, the region of the outermost bar underwent the smallest seabed change, so it provided basis for the determination of the depth of (nearshore) closure there. However, offshore of the rather flat and long crest of that bar, the two surveys diverged significantly on the offshore slope of the outermost bar at depths visibly greater than 8 m. This phenomenon was also found in other profiles and was discussed in detail in Różyński and Szmytkiewicz (2018).…”

“…6. Empirical equilibrium profile at km 149, after (Różyński and Szmytkiewicz 2018) quasi-bar structure. The smaller bar remained close to the location of bar 3 from 2005, with its crest at 3.8 m depth, located slightly onshore of the inflection point of the empirical equilibrium profile from 2005.…”

“…The goal of the paper was to relate the identified wave energy dissipation patterns to local, man-made or natural, coastal morphological features along a fairly long and diverse coastal segment in Poland between the western breakwater of the Władysławowo harbour (km 125 of the national coastal chainage) and a beach east of Lake Sarbsko (km 174), see (Różyński and Szmytkiewicz 2018). Wave energy dissipation patterns were identified using the empirical equilibrium profile concept for two sets of geodetically fixed bathymetric profiles measured in 2005 and 2011 for monitoring purposes.…”

This paper analyses cross-shore bathymetric profiles between Władysławowo (km 125 of the Polish coastal chainage) and Lake Sarbsko (km 174) done in 2005 and 2011. Spaced every 500 m, they cover beach topography from dune/cliff crests to a seabed depth of about 15 m. They were decomposed by signal processing techniques to extract the monotonic component of beach topography and to perform a straightforward assessment of wave energy dissipation rates. Three characteristic dissipation patterns were identified: one associated with large nearshore bars and 2–3 zones of wave breaking; a second, to which the equilibrium beach profile concept can be applied; and a third, characterized by mixed behaviour. An attempt was then made to interpret these types of wave energy dissipation in terms of local coastal morphological features and the underlying sedimentary characteristics.

Coastal erosion is a pervasive global phenomenon, exemplified by the Hel Peninsula situated in the Gulf of Gdańsk, the southern Baltic Sea. The geological constitution of the Hel Peninsula, characterized by sandy and loosely consolidated material, predisposes its coastal zones to continual morphological changes. The peninsula’s limited width and elevation exacerbate shoreline erosion, particularly during periods of heightened storm activity. This study scrutinizes the effectiveness of coastal nourishment interventions, with a specific focus on segments influenced by the Władysławowo port and the Kuźnica vicinity, over several years. This specific section of the coast serves as a significant case study due to its role as a transit zone for sand transport along the whole peninsula. Protective measures, including shore nourishments and coastal groynes, aim to mitigate erosion impacts. Utilizing Airborne Laser Scanning (ALS) data spanning from 2008 to 2022, erosion dynamics were analyzed. The analysis reveals significant erosion patterns coinciding with the frequency and volume of nourishment material deposition, particularly evident in heavily nourished areas proximate to Władysławowo and Kuźnica. Despite persistent monitoring endeavors, persistent erosive trends pose imminent threats to Kuźnica’s infrastructure, necessitating further research into the efficacy of implemented coastal protection measures.
