			====Example====
			The following images show the effect of the different options on both land and water under a bridge. The elevation data is set up such that it is slightly raised under the bridge, as often happens; the bridge deck itself is included in the terrain elevation data, or its support pillars, both on land and water. As can be seen below, the '''Lowest''' option selects the lowest terrain value under the bridge for water, but not on land.

			The water model uses an elevation model for the surface flow calculations. This setting defines how to include bridges in this elevation model:
	{{nominal list\|zeroindex=true		{{nominal list\|zeroindex=true
	\|\|'''Lowest''': ~~Lowest~~ elevation point from ~~Terrain~~ below bridge is used, when the terrain is '''[[Water (Terrain Attribute)\|water]]'''.		\|\|'''Lowest''': The lowest elevation point from the terrain elevation (DTM) below bridge is used, when the terrain is '''[[Water (Terrain Attribute)\|water]]'''. Otherwise the behavior is similar to '''Terrain'''.
	\|\|'''Terrain''': ~~Use standard~~ elevation ~~from Terrain~~. ~~Bridges are excluded from~~ the ~~DEM, allowed water~~ to ~~flow as if they didn't exist~~.		\|\|'''Terrain''': Under bridges, the terrain elevation (DTM) is used, otherwise the [[#Notes\|limited]] surface elevation (DSM) is used. Water can flow under the bridge according to the terrain elevation.

Bridges and [[Align elevation (Function Value)\|floating]] ~~Constructions~~ are included in the DEM, blocking water flow.		\|\|'''Bridge''' : Use bridge deck as elevation.
