Breach width (Water Overlay)

Icon	Key	Unit	Range	Description	Default value
	BREACH_WIDTH	m		The initial width of the breach.	10000

Notes

• The width is used in the breach growth formula. It's calculated value throughout the simulation can be inspected using an object measurement.
• For breach cell activation, the width is converted to a cell distance. Breach cells within the width-distance to the center cell of the breach are set active.
