Abstract

Current, sea level and bed load transport are investigated in the Great Bay Estuary, New Hampshire, U.S.A. - a well-mixed system with low freshwater flow and having main channel tidal currents over 2 m/sec. Current and sea level forced by the Mi-Mi-Ma tide at the estuary mouth are simulated by a vertically averaged, nonlinear, time-stepping, finite-element model. The hydrodynamic model uses a fixed boundary computation domain and accounts for flooding-dewatering over tidal flats by making use of a groundwater component. Inertia terms are neglected in comparison with pressure gradient and bottom friction terms, which
