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_STORAGE m³/m² Water storage (m³/m²) How much water this construction can store.
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.
FLOOR_HEIGHT_M m Floor height (m) The height of a floor in a construction. Additionally each section of a construction can have a different amount of floors.
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.
