“…An impact analysis of the storm surges in relation to the threshold values of the dunes erosion (Furmańczyk, Dudzińska-Nowak 2009;Furmańczyk et al 2012) provided evidence of 170 heavily erosive storms at the Polish coastal from 1972 to 2008, which caused dune loss of more than 350 m 3 km -1 (including 84 extreme erosive storms with the loss of dune sediments of more than 2,200 m 3 per km of the coast). There were no statistically significant trends in storm frequency causing heavy and extreme dune erosion during the study period.…”

The study looked at the temporal and spatial variability of dune erosion in the Polish Baltic coastal zone in the period 1972–2008. The dynamics of coastal dune erosion in the area are presented in relationship to the main hydro-meteorological factors: storm surges and types of atmospheric circulation. The greatest destruction of the coastal dunes in Poland was observed on sandbar sections, where the erosion was over 100,000 m3 per 1 km, causing dune baseline retreat by several tens of meters. The main causes of this considerable coastal erosion are the sudden rise of the sea level and the waves during extreme storm surges, when the loss of dune sediment across the entire Polish Baltic Sea coastal zone can reach about 400,000 m3. These extremely erosive storm surges are particularly generated by cyclonic atmospheric circulation, which accounts for more than 52% of such surges from the north-west, north, and west. It was also found that sea level increases of more than 1 meter (about 602 cm) above the mean sea level (about 500 cm) can result in significant erosion of coastal dunes in Poland (>100,000 m3). However, there is a relationship between the intensity of the dune erosion and sea level. The results of the present study could be applied to studies of Baltic coastal dunes functioning in the lagoon-spit coastline, especially in the stretch from Estonia to Germany.

“…The frequency analysis of extremely severe storm surges in reference to the threshold values of dunes at the Dziwnowska Sandbar (Furmańczyk, Dudzińska-Nowak 2009;Furmańczyk et al 2012) presented the occurrence (between 1986 and 2008) of 16 severely abrasive storms generating losses of dunes >5,000 m 3 and 7 extremely abrasive storms with losses of dune sediments >31,000 m 3 .…”

“…The detailed characteristics of a line-formed arrangement of dune ridges and plant succession related to the development stage of dune coasts were presented, among others, by Piotrowska, Gos (1995), Łabuz (2002, 2005a), Piotrowska (2003) and Łabuz, Grunewald (2007). Extensive issues related to the morpho-dynamics of dune coasts and their abrasion rate, among others, as a result of the occurrence of extreme storm surges, were presented by Łabuz (2005a), Furmańczyk, Dudzińska-Nowak (2009), Łabuz, Kowalewska-Kalkowska (2011), Wiś niew ski, Wolski (2011), Furmańczyk et al (2012). Climatic changes, sea level changes and characteristics of thermal-precipitation conditions within the coastal area of the Pomeranian Bay were dealt with, among others, by Wróblewski (1996), Furmańczyk, Musielak (1999), Plag, Tsimplis (1999), Świątek (2011), Łabuz (2012) and Tylkowski (2013a, b).…”

This paper presents the temporal and spatial variability of the abrasion dynamics of the dunes located on the coast of the Southern Baltic Sea within the Polish section of the Pomeranian Bay between 1986 and 2008. The study presents long-term tendencies and daily dynamics of coastal dunes abrasion, being the consequence of intensive storm surges. Systematic, quantitative measurements of the abrasion of dunes were performed by the Maritime Offices in Szczecin, Słupsk and Gdynia within the sections of the dune coast most severely affected by abrasion. To determine the origin of the abrasion of dunes, the key hydro-meteorological conditions that determine the geomorphological changes of coastal sea areas, such as types of atmospheric circulation and the maximal sea levels during storm surges, were reviewed. The study also shows the maximal sea level thresholds that can determine the potential dynamics of coastal dunes abrasion at the Pomeranian Bay.

“…Distinct thresholds for significant erosion of dunes have been identified that suggest sea level often provides a fundamental control on the geomorphic effectiveness of storms (Esteves et al, 2012;Furmańczyk, Dudzińska-Nowak, Furmańczyk, Paplińska-Swerpel, & Brzezowska, 2012). Pye and Neal (1994) also identify a close relationship between dune behaviour and beach characteristics; a negative dune sediment budget was associated with falling beach levels and a reduction in dune erosion rates was expected following rising beach levels.…”

a b s t r a c tEroding coastlines composed of sequences of till, carbon rich peat and sand layers are characteristic of many formerly glaciated coastlines due to the interplay of relative land and sea levels. Dune cliffs cut into these materials represent one of the most sensitive systems to the processes of coastal change. Establishing appropriate scales for the quantification and analysis of change in coastal dune cliffs remains limited by the speed and nature of change, the intensity of environmental processes and the challenges of achieving adequate survey control. This paper presents the results from multi-scale analyses into the behaviour of dune cliffs on the northeast coast, UK, over a 118 year period. Repeat unmanned aerial vehicle (UAV) survey differences have been used to identify and quantify system behaviour, set in context with historic map comparisons. At the landform scale, monthly dune cliff dynamics have been analysed over the course of a year with terrestrial laser scanning (TLS) in order to gain insights into the drivers of contemporary dune cliff behaviour. Finally, pseudo three-dimensional ground-penetrating radar (GPR) data are used to trace subsurface stratigraphy from which the potential extent of stored carbon (in excess of 100 t over 50 m of monitored dune cliff) at risk of release by coastal erosion over the next 50 years can be calculated. The consideration of multi-scale changes over time periods relevant to well-constrained sea level change has revealed a complex combination of failure mechanisms that have resulted in an acceleration in dune cliff recession (particularly over the last decade) and a form change to shallower, divergent profiles. This potential acceleration in contemporary dune cliff response holds significant implications for both coastal management and the contribution of this poorly quantified input to the coastal carbon flux.
