From Tygron Support wiki

Icon Attribute Unit Description Default value
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 threshold of the culvert. 10

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.
