An Evaluation of Boundary Condition Specification for a Littoral Hydrodynamic Model

Abstract

Littoral hydrodynamic models are valuable tools for characterizing near-shore waves and currents. There are a number of ways to prescribe boundary conditions for these models. A tide model is used to obtain astronomic boundary conditions, and a regional model can provide time-series boundary conditions. We investigate the differences imposed by these two types of boundary conditions for 4 model cases: a two-dimensional and a three-dimensional case at two locations. In addition, we investigate how variations in the temporal resolution of the time-series boundary condition and in the horizontal resolution of the regional model affects the model's results.
