Icon Attribute Unit Range Description Default value
Waterwizard icon bridges.png BRIDGE_ELEVATION nominal Specifies the mode by which bridges are include in the elevation model, used for the water calculations. Lowest

0. Lowest: Lowest elevation point from Terrain below bridge is used.
1. Terrain: Use standard elevation from Terrain. Bridges are excluded from the DEM, allowed water to flow as if they didn't exist.
2. Bridge : Use bridge deck as elevation. Bridges and floating Constructions are included in the DEM, blocking water flow.

Notes

  • When using Bridge mode, it is still possible to model the flow from one side of a bridge to the other by using a Culvert.
