Abstract

In this study, we apply the traditional hydraulic engineering approach to model an inter-connected multiple-bay-inlet system that can represent the Great South Bay-Moriches Bay system on Long Island, New York. We show that the hydraulic model captures the essential physics of the system, despite its apparent simplicity in mathematical expressions. The model gives good estimates of bay tidal transmissions, including the tidal ranges, phase lags, and the flood-ebb asymmetry behavior in Moriches Bay. The hydraulic modeling results compare well with the simulations from a 3D coastal ocean circulation model, in particular the changes in bay tides due to the breach of Old Inlet by Hurricane Sandy. The modeled inlet discharge rates are in good agreement with the observations.
