“…No grey coastal protection structures are present. From the seaward side to inland, Langeoog's morphology consists of a natural sandy beach followed by foredunes and older dune landscapes with dunes up to 20 m. In the southwest, Langeoog has extensively large areas with salt marshes [2,6,46,47].…”

For the restoration and maintenance of beach and dune systems along the coast, knowledge of aeolian sediment transport and its interaction with coastal protection measures is required. As a nature-based solution, sand trapping fences can be an integral part of coastal protection measures initiating foredune development. There are few detailed studies on aeolian sediment transport rates on coastal dunes and sand trapping fences available to date. Thus, in this work, we present the results of field experiments conducted at the beach, coastal dune, and sand trapping fence on the East Frisian island Langeoog. The vertical sediment flux profile was measured by vertical mesh sand traps, and saltiphones measured the instantaneous sediment transport. A meteorological station was set up to obtain wind data. On the beach, dune toe, and dune crest, the stationary wind profile can be described well by the law of the wall. Saturated aeolian sediment transport rates on the beach and dune toe were predicted by widely used empirical models. Between the sand trapping fence, these empirical transport models could not be applied, as no logarithmic wind profile existed. The upwind sediment supply reduced after each brushwood line of the sand trapping fence, thereby, leading to increased deviation from the saturated conditions.

“…Adventitious rooting and sprouting capacities are species-specific and of genetic predisposition. Pioneer plants such as willows, poplars, tamarisks or privets have high regenerative potential and can be applied as live stakes and poles (Lavaine et al 2014, Florineth 2012, Hacker and Johannsen 2011, Jensen et al 1997.…”
