In-Line (Rectangular) Weir

The flow is given by:

The weir coefficient can be further given (for weirs stretching across the channel) by:

g	=	gravity
b_e	=	effective width (essentially the width)
H_e	=	effective head (essentially the head)
C_v	=	0.602 + 0.075 h/p for full width weir0.587 - 0.023 h/p for fully contracted weir where p = depth of weir crest above channel bottomh = head

Note: The weir coefficient required by the program is the C coefficient, not C_v.
