“…Terrestrial sediment yields are low, and the coast is mesotidal and routinely impacted by winter storms of moderate intensity. Past periods of high accretion rates in Wadden Sea marshes have been connected to intervals of high storm activity (Schuerch et al., 2012); and similar to our observations in the North/South River Estuary, higher suspended sediment concentrations have been observed on the flood tide than the ebb during storm events (Bartholdy & Aagaard, 2001; Hache et al., 2021).…”

“…Human decision-making impacts erosion at the coast and thus has the potential to impact marsh sediment supply. For example, in the Wadden Sea, Hache et al (2020Hache et al ( , 2021 observed that less than half the available suspended sediment mobilized during storms was able to accumulate on marshes behind artificial revetments and breakwaters. As of 2013, nearly 27% of the Massachusetts coastline was armored by some form of coastal protection (Fontenault et al, 2013).…”

Tidal salt marshes are critical protectors of the coast; they buffer against erosion and flooding (Möller et al., 2014), sequester carbon (Chmura et al., 2003), provide habitat to juvenile species and migratory birds (Boesch & Turner, 1984;Hughes, 2004), and filter pollutants and excess nutrients (Sousa et al., 2010). Coastal wetland maintenance involves complex biophysical feedbacks between clastic (i.e., inorganic) sediment supply, nutrients, plant growth, and flooding (Deegan et al., 2012;Kirwan & Megonigal, 2013). Deposition of clastic sediment in the form of clays, silts, and sands allows marshes to accrete faster than would be possible via in-situ organic production alone; thus, the availability and delivery of clastic sediment is a key factor in determining salt marsh resilience to erosion and future sea level rise (e.g.,
