Perform 2D modeling and combined 1D and 2D modeling. The 2D flow modeling can be used for:

• Detailed 2D channel modeling
• Detailed 2D channel and floodplain modeling
• Combined 1D channels with 2D floodplain areas
• Combined 1D channels and floodplains with 2D flow areas outside of the levees
• Connect 1D reaches into and out of 2D flow areas
• Connect a 2D flow area to 1D storage area with a hydraulic structure
• Multiple 2D flow areas in the same geometry
• Connect multiple 2D flow areas with hydraulic structures
• 2D dam breach analyses
• 2D levee breach analyses
• 2D bridge modeling (without pressure and bridge deck overflow)
• Mixed flow regimes (e.g., subcritical and supercritical regions, hydraulic jumps, etc.)
