Abstract:

This paper summarizes our first-year results of an ongoing multi-discipline project, which examines the physical processes of wetlands erosion and loss in coastal Louisiana. Our task is focused on field measurements of two surface flow components: the channel flow in a tidal bayou and surface overland flow across adjacent tidal marshes. The preliminary results showed, in a tidal bayou, an asymmetry of velocity profile and a more ebb-dominated channel flow; whereas, in tidal marshes, the surface velocity was more flood-dominated and strongly density-dependent.
