  Citation × Citation Citation Abstract Copy Title: Theoretical Basis for the CE-QUAL-W2 River Basin Model Author: Wells, Scott A., Cole, Thomas M. Year: 2000 The primary objective of this research is to integrate a riverine model into the existing W2 code that would provide the capability for modeling entire watersheds. This task was accomplished by the following steps: • Formal derivation of governing equations and solution algorithm with general channel slope • Detailed analysis of algorithm for linking branches and smooth implementation of boundary conditions between branches • Algorithm development and changes to basic model code (including branch definitions with slope, slope correction to solution algorithm, transfer of momentum between internal branches) These tasks were performed with the following constraints and initiatives: • Utilize the same solution algorithms as the existing code for hydrodynamics and water quality for the riverine system • Allow momentum transfer between adjacent branches for internal head boundary conditions • Refine the turbulence closure hypothesis for riverine sections Title: Theoretical Basis for the CE-QUAL-W2 River Basin Model Author: Wells, Scott A., Cole, Thomas M.

Year: 2003 CE-QUAL-W2 is a two-dimensional, longitudinal/vertical, hydrodynamic and water quality model. Because the model assumes lateral homogeneity, it is best suited for relatively long and narrow waterbodies exhibiting longitudinal and vertical water quality gradients. The model has been applied to rivers, lakes, reservoirs, estuaries, and combinations thereof. The application of CE-QUAL-W2 requires knowledge in the following areas: 1. Hydrodynamics 2. Aquatic biology 3. Aquatic chemistry 4. Numerical methods 5. Computers and FORTRAN coding 6. Statistics 7. Data assembly and reconstruction. Water quality modeling is in many ways an art requiring not only knowledge in these areas but also experience in their integration. A word of caution to the first time user - model application is a complicated and time-consuming task.
