Drainage q (Water Overlay)

Icon	Key	Unit	Range	Description	Default value
	DRAINAGE_Q	m3/m2 per second		The drain capacity per second, where the capacity is defined in cubic meters per square meter.	0.01

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 drainage used to allow or deny water flowing across.

Notes

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