Weir target level (Water Overlay)

Icon	Key	Unit	Range	Description	Default value
	WEIR_TARGET_LEVEL	m + datum		The Weir can be configured to adjust it's height automatically in order to reach the target upstream water level. This parameter is optional.	n/a

Notes

• The interval before re-evaluating the Weir height is configured using the Water Overlay's model attribute WEIR_MOVE_INTERVAL_S.
• This value is set as a single value, not an array.
• The weir can move with a distance defined in the overlay with the model attribute WEIR_MOVE_STEP_M.
• The weir's movement range can be set using the overlay's model attribute WEIR_MOVE_RANGE_M. This can be interpreted as the maximum allowed difference in the configured WEIR_HEIGHT and the adjusted weir height.
