Book excerpt: A two-dimensional finite difference tidal hydrodynamics model has been adapted to Masonboro Inlet, North Carolina. The model was initially calibrated to simulate prototype conditions of September and October 1969. Operational runs were then undertaken to simulate tides and currents corresponding to pre-project undeveloped inlet conditions of November 1964 and modified inlet and north jetty conditions of June 1967. For each case, the model was operated with mean and spring ocean tides. The tidal hydrodynamics model applied at Masonboro Inlet uses an explicit numerical solution of the basic equations of motion and the continuity equation. As structured, the model includes bathymetric data for the inlet, bottom roughness, inundated areas and other features of the system. Because of the size and detail required in the simulations, a dual-model approach is employed. In this technique a coarse grid model is utilized to compute tidal flows which in turn are applied as boundary conditions to a finer sub-model of the immediate inlet area. Special requirements necessary for sequential operation of the two models are presented. (Author).

Book excerpt: Four models of Masonboro Inlet, North Carolina, have been developed in a program for assessing the value of models in investigating coastal inlet hydraulics problems. A distorted scale, fixed-bed physical model, a lumped parameter numerical model, and two two-dimensional numerical models were included in the study. Hydrodynamic equations which describe the two-dimensional flow in tidal inlets are developed in an appendix to this report. The Navier-Stokes equations are integrated vertically and time-averaged to form the governing equations for two-dimensional flow. This procedure eliminates a great deal of unnecessary detail about small-scale motions but retains terms descriptive of the interactions between small- and large-scale flow. A comparison of experimental results obtained with a physical model and calculations made with numerical models with the prototype records shows that, in general, the models simulate tidal height more satisfactorily than tidal current. Results obtained with one of the two-dimensional numerical models were much inferior to the results obtained with the other. The basic design of both two-dimensional numerical models was similar, but there were many subtle differences, indicating that a clear understanding of the modeling process is essential to success in modeling tidal flows.

Book excerpt: HYDTID is constructed and formulated in such a manner that the sequential flow of program control necessary for solution using high speed digital computers can be easily understood. The basic computer language used is Fortran V and the model has been successfully applied using the CDC 6600 and 6400, the UNIVAC 1108 and 1106 and the RCA Spectra 70/45 computers. In its present form HYDTID is essentially machine independent. The computation time and storage depend on the size of the system being modeled, the mesh size and time step being used, the number of computational or water cells in the grid network, and the length of simulation time desired. For the Masonboro Inlet problem, the coarse grid model required about four minutes of UNIVAC 1108 time to simulate one 12.5 hour tidal cycle and to generate the input flows for the fine grid sub-model. The fine grid sub-model required about 40 minutes of computer time to simulate one cycle.
