Abstract

Berm formation and morphological development of the beach face have been observed during a neap-neap tidal cycle on the gently sloping and accreting beach at Vejers, Denmark. This berm development can be described through both the neap-berm, ridge-and-runnel and berm-ridge development concepts proposed by Hine (1979), and all 3 stages were observed during only 3 tidal cycles. The factors controlling this fast transformation were the gentle slope of the cross-shore profile, rapid water level translation rates, substantial swash overtopping of the berm, and low infiltration rates. Despite the onshore migration of intertidal bars and berm formation, no net foreshore accretion took place during the field campaign. This was largely due to the formation of rip channels with strong rip currents cutting through the intertidal bars and the berm, which acted as a sediment drain in the profile
