Extensive model-data comparisons of sea surface elevations and vertically-averaged velocities are performed on the Peconic Bays Estuary, New York, a system of interconnected bays where barotropic flow conditions are likely to persist. The data base consists of one-month velocity records from 26 current meters, and a full year of surface elevations from five tidal gauges. Numerical simulations are performed with a two-dimensional (2D) finite element model that solves the vertically integrated momentum and continuity equations. Sensitivity analysis of the system's response to the bottom friction coefficient, eddy viscosity, and cross-sectional area of the estuary entrance is also assessed.
