Surface water (Water Overlay)

Icon	Attribute	Unit	Range	Description	Default value
	SURFACE_WATER	nominal value		Whether and how water on the surface is simulated during the calculation.	n/a

There are a few modes available for the Water Module for surface water simulation:

• None. No surface water flow.
• Complete Saint-venant surface water simulation
• Grid Average Water is simulated by averaging water levels. Useful for groundwater simulations over a long period of time with low impulse water movement.

Possible values

• 0: None
• 1: Complete (selected by default for groundwater, flooding and rainfall overlay)
• 2: Grid Average
