Weir coefficients are not being divided by (2g)^(0.5) = 8.02496, which is
required according to the DHI documentation for weirs with specified
coefficients.
DHI indicates their weir equation is
Q = CL*(2g)^(0.5)*H^(1.5)
where Q = flow, C = weir coefficient, L = weir length, g = grav const = 32.2
ft/s, and H = head above weir crest
SWMM's weir equation, and on which our master data is based, is stated as
Q = CLH^(1.5)
Therefore, to use the equivalent C in DHI's equation, the C from our master
data must be divided by (2g)^(0.5) to be equivalent.
