Abstract
The Great Bay area is interested in many research groups in UNH. In this study, hydrodynamics model for the Great Bay is developed. The model resolves realistic forcing configuration including not only tides but also subtidal currents, atmospheric forcing, and river discharges from major rivers. The model was used to hindcast hydrodynamical environment of the Great Bay from 2007 to 2024 and shows reasonable comparison with observations for all variables (sea surface elevation, velocity components, temperature and salinity). Especially, extreme flooding events are successfully captured by the model. The flooding events are consistently accompanied by the Nor’easters, but sensitivity experiments show that they are triggered by not local atmospheric forcing but subtidal boundary conditions. Additional theoretical studies are conducted to study the dynamics of extreme flooding events in the Great Bay.
