Calculation of Dune Profile Changes Generated by Hurricane: Preliminary Results

Abstract

The paper presents the main theoretical concepts related to methods of calculating the erosion rate for sandy dunes on natural coasts, namely, the beach equilibrium profile and incident waves. To illustrate calculations of dune erosion in the vicinity of the Coastal Research Station (CRS) in Lubiatowo, the Xbeach model (an incident wave model) was used. The calculations were carried out for hydrological and hydrodynamic conditions that accompanied Hurricane Ksawery (December 6–8, 2013). The results of the calculations were compared with the measured data. A satisfactory agreement was obtained between the predicted and measured results.

Artificial Nourishment Schemes along the Polish Coast and Lagoon Shores between 1980 and 2020, with a Particular Focus on the Hel Peninsula

“…However, only a few focused on the Polish coast. Conversely, the Polish shoreline has been extensively researched in terms of geology or aeolian processes [1,2,34]. To fulfil the purpose of this paper, we reviewed the specialised literature, the main source of which was the Library of the Maritime Institute in Gdansk.…”

“…Notes: 1 A total of 80 thousand m 3 were deposited on the Messina Spit as part of reconstructing the fairway on Wisła Śmiała. 2 There is no chainage defined for the Szczecin Lagoon.…”

“…Notes: 1 A total of 80 thousand m 3 were deposited on the Messina Spit as part of reconstructing the fairway on Wisła Śmiała. 2 There is no chainage defined for the Szczecin Lagoon. Until the end of the 1980s, along the open sea coast, single artificial nourishment operations were implemented only in the region of Kołobrzeg and Ustka.…”

“…The area experiences its most significant development during storm surges, driven by the direct impact of wind-generated waves. Consequently, abrasion processes affecting beaches, dunes, and cliffs can be observed here, and along the majority of the Polish coastline, coastal erosion tends to prevail over processes involving marine and aeolian accumulation [1][2][3][4]. One of the methods of technical coastal protection against erosion and storm flooding is artificial beach nourishment with sand imported from the seabed [5][6][7][8][9].…”
