Flow hydrodynamics in tidal marsh canopies
WebThe 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 alterniflora, Juncus roemerianus, and Distichlis spicata canopies using hot‐film anemometry sensor arrays. … WebMeanwhile, for both the V. natans and the P. malaianus canopies, the decrease of frontal area in the lower part of the canopy layer makes flow traverse in this region, forming a fast flow zone relative to the upper part of the canopy layer. The deflection of flow through the lower part of the canopy produces a local velocity maximum near the ...
