HIVEL2D DESCRIPTION
HIVEL2D
HIVEL2D is a free-surface, depth-averaged, two-dimensional finite element model designed specifically to simulate flow in typical high-velocity channels. HIVEL2D is applicable for flow fields that contain supercritical and subcritical regimes as well as the transitions between the regimes. HIVEL2D provides numerically-stable solutions of advection-dominated flow fields containing shocks such as oblique standing waves and hydraulic jumps.
The system of nonlinear equations is solved using the Newton-Raphson iterative method. The Newton-Raphson method was selected for this model because the nonlinear terms in high-velocity channel flow fields are quite significant. Stresses are modeled using the Manning's formulation for boundary drag and the Boussinesq relation for Reynolds stresses. Eddy viscosities are approximated using an empirical relation based on Manning's coefficient and local flow variables.
SMS supports both pre and postprocessing for HIVEL2D.
