Inlet lower threshold (Water Overlay)

Icon	Key	Unit	Range	Description	Default value
	LOWER_THRESHOLD	m + datum	-10000 to 10000	If a lower threshold is set, water will only flow into the model through this inlet until the water level at the point of this Inlet is equal to or greater than the threshold. If the threshold is not set, the amount of water flowing in is not limited in this fashion.	None

This attribute can be defined as values over time, using an array of values defining start-time. This allows users to more dynamically define the target water level this Inlet maintains.

Notes

• The INLET_Q should be 0 or positive. Otherwise, the Inlet is not configured to let water flow in.
• When using a dynamic LOWER_THRESHOLD, a maximum of 10.000 values (5.000 pairs) can be defined.
