Source: https://erdc-library.erdc.dren.mil/jspui/ A time-varying three-dimensional (3-D) numerical hydrodynamic, salinity, and temperature model called CH3D-WES has been developed. The water surface, 3-D velocity field, and 3-D salinity and temperature fields are computed. Major physical processes affecting circulation and vertical mixing of a large water body are modeled. A particular feature of the model is the solution of transformed equations on a boundary-fitted grid in both the horizontal and vertical planes. The horizontal grid is a general nonorthogonal curvilinear grid, whereas the vertical grid is normally referred to as a sigma-stretched grid. This user's guide presents a detailed discussion of the theoretical aspects of the 3-D model (e.g., basic equations, boundary conditions, turbulence closure, etc.). This discussion is followed by a discussion of the organization of the computer code and input data requirements. |
