Abstract: The transport of particulate and dissolved matter on the surface of coastal marshes is controlled by the hydrodynamic characteristics of over-marsh flows. High-frequency (5 Hz) in situ measurements of flow speed were collected in Spartina alternijlora, Juncus … WebHerbaceous marshes include two distinct sub-types: floating marshes regionally referred to as flotant and newly formed marshes within large river deltas (Mitsch & Gosselink, 2015). With the continued influence of tidal exchange absent salinity stresses, tidal freshwater wetlands tend to be high in diversity and productivity. dana bly artist
