Control Curve Commands
The dimensions and units of the curve are determined by the control rules which reference it. For example, take the control statement from a control set which uses US – CFS, Ft, cubic Ft units:
RULE MC1
IF NODE N2 DEPTH >= 0
THEN WEIR W25 SETTING = CURVE C25
The curve has dimensions of Depth (ft) vs Setting (unitless).
