Drainage q (Water Overlay)

Icon	Key	Unit	Range	Description	Default value
	DRAINAGE_Q	m3 per second	-3.4028235E38 to 3.4028235E38	The maximum pump flow capacity, defined in cubic meters per second.	1

This attribute can be defined as values over time, using an array of values defining interpolation-time. This allows users to dynamically define the drainage flow capacity over time.

Notes

• When using a dynamic DRAINAGE_Q, a maximum of 10.000 values (5.000 pairs) can be defined.
