Abstract Salt marshes are widespread in estuarine coastal areas and one of the most productive natural ecosystems world. More importantly, role salt protection is increasing interest, as significantly reduce wave height stabilize substrates. However, application hydrodynamic models for marsh management still uncommon. In this study, TELEMAC used to set up a hydro-morphodynamic model simulate dynamic process study area. After that, influence stress on under conditions was analysed feasibility applying artificial structures restore discussed. Finally, long-term evolution platform modelled. The results show that vegetation strongly influenced by dynamics. restoration measures such submerged dikes have potential or rehabilitate attenuating currents tidal flats. contains both raising channel incision, which forms unique landscape marsh. research can provide theoretical support wetlands contribute disaster prevention mitigation areas.

In face of sea-level rise and increasing risks for storm impacts on shorelines, there is a growing demand developing nature-based flood defenses, example by restoring or creating salt marshes in front engineered structures such as dikes. However, can only optimally provide defense if their sediment beds are erosion resistant, even under very high flow velocities. It remains unknown how fast strength develops restored created defense. Therefore, this study investigated 1) type, 2) tidal drainage depth duration, 3) pioneer vegetation species drive the development rate strength. A controlled experiment was set up with pots filled two types, which were either left bare planted Spartina anglica Scirpus maritimus, dominant marsh pioneers NW Europe. All treatments subjected to four different regimes duration. The results showed that sandy mud (with 37% silt clay fraction) led much stronger sediments than fine 77% fraction). Sediment higher deeper longer presence increased effect maritimus anglica. Plant roots directly, also seemed increase through enhanced evaporation transpiration. From these it be concluded restore create resistant defense, essential ensure form at relatively elevations from well-draining sand-mud mixtures, thereby ensuring growth.

In this paper we describe one aspect of nature-based flood protection by foreshores in hybrid defences and discuss how foreshore ecosystem restoration can contribute to protection. Flood consists prevention, grey, green or defences, impact reduction, spatial planning limit damage crisis management exposure. Reduction is increasingly important because no defence system provide 100% safety, especially with climate change sea level rise. study aim understand visualize the effect characteristics (i.e., width, elevation erodibility) on flooding hinterland defences. As it difficult research real dike breaches, do an explorative flume analyse a mimicked breach hinterland. Our physical scale model showed presence non-erodible reduces With regards characteristics, mainly erodibility are important, while differing width has little additional influence. Already narrow reduced findings strengthen appeal integrate Nature-based Grey be turned into even if there limited space for restoration, instance managed realignment.

Abstract Tidal marshes can contribute to nature‐based shoreline protection by reducing the wave load onto shore and erosion of sediment bed. To implement such requires ability quickly restore or create highly stable erosion‐resistant tidal at places where they currently do not yet occur. Therefore, we aim identify drivers controlling rate which stability builds up in young pioneer marshes. Sediment proxies were measured over age gradients spanning 18 years six marsh sites Western Scheldt estuary (SW Netherlands): Three dominated Spartina anglica , a densely growing species, three Scirpus maritimus less species. Our results showed that presence increased shear strength compared unvegetated flat, while did not. This difference may be related contrasting clonal expansion strategies root densities these two increase further beyond 6 coverage implying observed effect on occurs fast (<6 years). Furthermore, often with decreasing inundation duration water content. study shows order beds future restoration projects, should vegetated well‐draining, cohesive sediments relatively high intertidal elevation. Although development resistance takes time, our demonstrates case marshes, bed already reached after years. The within years, combination attenuation accretion, offers promising perspectives projects as strategy start deliver its protective service reasonable amount time.

Salt marshes are a valuable ecosystem with coastal protection potential, for example by absorbing hydrodynamic energy, increasing sedimentation and stabilizing the soil. This study investigated biomechanical properties of Spartina anglica to improve future models wave-vegetation interaction. To fully understand correlations between hydro- biomechanics, vegetation from December 2021 July 2022 specimens collected field monthly. 551 were used determine during storm surge season high forces. Additional geometrical determined 1265 specimens. Three-point bending tests measured stiffness S (N/mm) maximum forces F max (N). Different phenological states observed over time separated analysis. These provide novel classification growth periods evaluating potential . Especially season, most specimen identified as broken shoots mean 1.92N/mm (using 304 samples) compared bottom part flowering in January 2.98N/mm 61 samples). The plant recognizing differences, based on state seasonality, can be explain reduce variability obtained campaigns.

Abstract Many tidal marshes have been lost by past land use changes, but are nowadays increasingly restored and created to provide valuable ecosystem services such as nature‐based flood erosion protection along estuarine shorelines. To be functional for shoreline protection, should develop resistant sediment beds. Here, we investigated which factors drive the spatial variations in strength resistance a developing marsh restoration site. Our results show that decreasing inundation frequency, sedimentation rate, better drainage led stronger consolidation deeper layers. This resulted greater strength, quantified here shear penetration resistance. Generally, was when had higher bulk density, while water fine fraction (= clay silt) content decreased strength. Overall, all measurement locations were relatively resistant, likely caused dense root network cohesive sediment. restore or create resilient thus aim sites with low moderate rates, mixtures of clay, silt, sand, well drained potential vegetation establishment. These conditions high likelihood resulting contribute protection.
