Terrain root depth m (Water Overlay)

Icon	Attribute	Unit	Layer	Range	Description
	ROOT_DEPTH_M	m	Surface		The depth of the roots of this surface terrain, relative to the surface. Water can be drawn from the underground and evaporated if the roots can reach it.

Terrains can be configured with plant-related attributes, similar to constructions configured as crops and foliage, allowing it to draw water from the underground and evaporate it.

Notes

For plants to evaporate water, both the ROOT_DEPTH_M and the WATER_EVAPORATION_FACTOR must be appropriately configured.
When a construction is present in any given location, the values for evaporation in the underground 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.
When there is no construction present on the surface, and the terrain has a ROOT_DEPTH_M of 0, the amount of evaporation which takes place in that location is 0.
