Culvert dem threshold m (Water Overlay)

Attribute	Unit	Description
CULVERT_DEM_THRESHOLD_M	m	The maximum distance a culvert's height can be below the terrain, for the terrain height to be adjusted to the height of the culvert.

Notes

• This functionality resolves some instances where a culvert, the endpoint of which rests on the slope of the edge of a waterway, would otherwise be forced to assume it lies much higher, causing it to not function correctly.
