Breach measurement distance m (Water Overlay)

Breach measurement distance m can be configured in Breach Growth step of a Flooding Overlay wizard.

Icon	Attribute	Unit	Range	Description	Default value
	BREACH_MEASUREMENT_DISTANCE_M	m	0 to 10000	Distance from the breach area to the automatic downstream water level measurement point, in the direction of the breach.	100

Notes

• This distance is only taken into account when not using a manually defined Breach level area.
• In order to place the measurement the breach area must also have a BREACH_ANGLE. Together they determine the location at which the point of measurement is placed.
• The downstream water level of the breach is used in the Verheij–van der Knaap growth formula.
• The measurement point is only placed if the calculated location is lower than the breach level, preventing invalid placement (e.g., on top of a building).
