Terrain water (Water Overlay)

Water

Water terrains are processed by the water model in a specific manner before the simulation is started. For each water terrain in the 3D world, the bottom of the water body is treated as a land surface in the same fashion as dry land. Water is then placed on it on the surface layer, up to the level defined by the overlapping water level area's WATER_LEVEL attribute. Terrains not marked as water terrain are not initiated with water.

Terrains marked as water are subject to an additional check for the WATER_STRESS result type. If the amount of water on a water terrain has not increased by more than ALLOWED_WATER_INCREASE_M relative to the water level area's water level, that terrain will not count as stressed for that result type. The amount of water on that location must be at least ALLOWED_WATER_INCREASE_M more than the water level area's water level.
