Abstract : HWEL2D is a free-surface, depth-averaged, two-dimensional model designed specifically for flow fields that contain supercritical and subcritical regimes as well as the transitions between the regimes. The model provides numerically stable solutions of advection-dominated flow fields containing shocks such as oblique standing waves and hydraulic jumps. HWEL2D has been verified by comparing computed model results with laboratory data. The findings of these tests are presented in Stockstill and Berger (1994). This report serves as a user's manual for HWEL2D Version 1.07. First, brief description of the model equations are presented. Next, step-by-step instructions are given to guide the user in creating the required input files. These input files include the geometry (numerical model computational mesh) file, the hydrodynamic parameters/boundary conditions file, and the initial conditions file. Finally, the numerical model output file is explained. Appendix A describes the boundary conditions. Appendix B describes problems with the model and solutions. Appendix C gives an example problem. Appendix D discusses the interpolation program.
