Avg terrain storage m (Water Overlay)

Average terrain storage can be configured in the Simulation Settings step, when the surface water mode set to Avg Terrain.

Icon	Attribute	Unit	Range	Description	Default value
	AVG_TERRAIN_STORAGE_M	m	0 to 10000	When determining the water level of a land cell that will be averaged, the level will ignore the part that is reserved for storage.	0,05

This storage amount will allow water to infiltrate into the surface and evaporate, before being averaged away into the water way.

Notes

• This option is only used when the surface water mode is set to Avg Terrain. In the later two cases, the situations in which this occurs is very limited, only for Sewer and drainage cells, since land type cells are not assigned for these modes.
