Breach level area (Water Overlay)

Icon	Key	Unit	Range	Description	Default value
	BREACH_LEVEL_AREA	ID of an Area		The Area item representing the downstream water level measurement area for the breach.	none

Notes

• To attach a breach level area to a breach using the configuration wizard, ensure that the desired level area does not have a BREACH_HEIGHT attribute but does have a BREACH_LEVEL_AREA attribute (set to -1, for example). That area is then selectable as an input area in the configuration wizard, in the step for breaches areas.
• A breach level area should be placed on a relatively flat surface. The heights of the water columns across a breach level area are only inspected; they are never changed directly by the breach.
• When a breach level area is not defined, the BREACH_MEASUREMENT_DISTANCE_M attribute in the Water Overlay is used to automatically place a point for measurement of the downstream water level.
