The Herring River in Wellfleet, MA is a tidally-restricted estuary system. Management options including potential restoration of unrestricted tidal flows require an understanding of pre-restoration sediment conditions

Meagan Gonneea checks on instruments at a tidal creek in Great Pond, Falmouth, MA. Daily tides drive exchange between coastal wetlands and adjacent estuaries. Here we have instrumented a tidal channel to measure those fluxes over a tidal cycle. When the marsh floods, material is imported from the estuary.
