Abstract:

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 7045 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.
