Weir height (Water Overlay)

Icon	Key	Unit	Range	Description	Default value
	WEIR_HEIGHT	m + datum		The height of the weir. Water can flow past the weir when the water level exceeds the weir's height.	n/a

This attribute can be defined as values over time, using an array of values defining interpolation-time. This allows users to more dynamically define the height used to allow or deny water flowing across.

Notes

• When using a dynamic WEIR_HEIGHT, a maximum of 10.000 values (5.000 pairs) can be defined.
• A Weir's height can also be configured to be automatically adjusting.
