Abstract : A timevarying threedimensional (3D) numerical hydrodynamic, salinity, and temperature model called CH3DWES has been developed. The water surface, 3D velocity field, and 3D 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 boundaryfitted 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 sigmastretched grid. This user's guide presents a detailed discussion of the theoretical aspects of the 3D 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.
