Abstract:

This report documents the use of the CELC3D computer code for the computation of two- or three-dimensional unsteady currents in coastal, estuarine, or lake waters based on the free-surface model described in detail by Sheng. The present version of the code is implemented on a VAX 11780, a virtual machine. It therefore contains no buffering scheme and is programmed to run entirely in the central memory. Since it has no buffering scheme, it contains no machine dependent inputoutput and, except for minor program changes, should run on any other virtual machine, e.g., the CDC cyber 203, or other non-virtual machine with sufficient memory. The CELC3D program solves the mean equations of fluid motion within a water body with respect to a right-handed Cartesian coordinate system located at the nominal water surface. These equations consist of the partial differential equations for surface displacement, vertically integrated velocities, three-dimensional velocities, temperature, salinity, density, and sediment concentration. The equations of motion are solved in dimensionless forms and are given in Appendix A in detail. The major variables and their corresponding FORTRAN names are given in Appendix B. Sheng presented numerous example calculations of the CELC3D model, including tidal currents in an open bight, wind-driven currents in a shallow lake, wind-driven currents in an open channel, formation and deepening of a thermocline, and tide- and wind-driven currents in the Mississippi coastal waters, etc. This report, for simplicity, only briefly presents the application to Mississippi coastal waters.
