Root depth m (Water Overlay)

Attribute	Unit	Function value	Description
ROOT_DEPTH_M	m	Depth of plant roots (m)	The depth of the roots of this construction, relative to the terrain height at the location of this construction. Water can be drawn from the underground and evaporated if the roots can reach it.

Crops and foliage

Constructions representing crops and foliage can draw water from the underground, allowing it to evaporate. This behaves in the same way as terrain which is configured as plants.

Notes

• When a construction is present in any given location, the values for evaporation will overrule any values set by terrain in the same location. To model underground evaporation without a construction, set these attributes on the applicable terrain type instead.
