ROOT_DEPTH_M | m | Surface | The depth of the roots is used to determine whether evaporation will occur from the groundwater. Alternatively, the root depth can also be configured with four values instead of one, which will be interpreted using Feddes transpiration model." |
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. The sequence should be defined in order of largest to smallest depth values and are interpreted as a 0-1-1-0 transpiration factor trapezium. Feddes_trapezium.png
Notes
- For plants to evaporate water, both the ROOT_DEPTH_M and the WATER_EVAPORATION_FACTOR must be appropriately configured.
- Trees typically have deeper root than crops.
- 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.
