Abstract

A frequency domain (harmonic) finite element model was developed for the numerical prediction of depth average circulation within small embayments. Such embayments are often characterized by irregular boundaries and bottom topography and large gradients in velocity. Previously developed finite element based time domain models require high eddy viscosity coefficients and small time steps to insure numerical stability, making application to small bays infeasible. Application of the harmonic method in conjunction with finite elements overcomes these problems. The model TEA, for Tidal Embayment Analysis, solves the linearized problem and is the core of a fully non-linear code presently under development. (A)
