Parameters

qSubCrit  Double
The subcritical discharge [m3/s]
dQdHups  Double
Derivative of Q with respect to upstream water level [m2/s]
dQdHdws  Double
Derivative of Q with respect to downstream water level [m2/s]
a  Double
Coefficient
b  Double
Exponent
upsD  Double
Upstream depth above sill level [m]
dwsD  Double
Downstream depth above sill level [m]
width  Double
Width of the weir [m]
delta  Double
Minimum headdifference. When head difference is below this linearisation is applied
