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.
| Attribute | Unit | Terrain 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. |
| 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. |
| WATER_EVAPORATION_FACTOR | factor | Water evaporation | How fast this construction can evaporate water from the underground. The weather's evaporation speed is multiplied by this factor to determine the rate of evaporation. |
| WATER_STORAGE_PERCENTAGE | fraction | Underground | The percentage (as a fraction) of the underground volume which can be filled with water. A lower percentage means the underground will be able to store less water, and the saturated zone will rise higher with the same amount of water in the underground layer. |
| CRITICAL_INFRASTRUCTURE | nominal integer | Critical infrastructure | Whether this construction is deemed a critical construction. 0 means the construction is never deemed impacted. |
| WATER_MANNING | s/(m1/3) | Surface | The Gauckler–Manning coefficient of the construction. |
| SUBSTANCE_A | x/m²s | The amount of substance A created per second per m² in this location. | |
| SUBSTANCE_B | x/m²s | The amount of substance B created per second per m² in this location. | |
| SUBSTANCE_C | x/m²s | The amount of substance C created per second per m² in this location. | |
| SUBSTANCE_D | x/m²s | The amount of substance D created per second per m² in this location. |
