Hydrological attributes of terrains (Water Overlay)
Revision as of 09:35, 5 April 2019 by Frank@tygron.nl (talk | contribs)
Terrains in a project have a number of hydrological properties which can influence the flow of water in a project. Because there is always both surface and underground terrain defined for the entirety of the project area, all cells are affected by all properties of terrains, unless a construction is present with overwriting values.
| Icon | Attribute | Unit | Type | Description |
|---|---|---|---|---|
| WATER | boolean | Surface | Whether the specified terrain is a water terrain. | |
| 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. | |
|
WATER_EVAPORATION_FACTOR | factor | Surface | How fast this terrain can evaporate water from the underground. The weather's evaporation speed is multiplied by this factor to determine the rate of evaporation. |
|
GROUND_INFILTRATION_MD | m/day | Surface | The speed at which water can flow vertically from the surface to the underground unsaturated zone. |
|
|
GROUND_INFILTRATION_MD | m/day | Underground | The speed at which water can flow vertically from the underground unsaturated zone to the underground saturated zone, and horizontally through across the saturated zone. |
|
WATER_MANNING | s/(m1/3) | Surface | The Gauckler–Manning coefficient of the terrain. |
