Morphodynamics of the replenished Baltic beach between Gdańsk and Sopot

The research area is located on the coast of the Baltic Sea, along the Gulf of Gdańsk. It includes a beach where sand replenishment was carried out in 2019. The aim of the study was to investigate the morphodynamics of beach deposits in replenishing and non-replenishing areas during one year. No environmental dynamic conditions sufficient to alter significantly the beach morphology and sediment characteristics occurred during the study period, November 2019 to August 2020. One storm event was recorded, but did not significantly affect the beachform. The transverse beach profiles, which were artificially recharged in June 2019, were lowered by 0.6 to 1.2 m. The greatest changes were caused by the erosive activity of the waters of the Jelitkowski Stream
