OverFlowFormulaCalcFreeWeirFlow Method

Calculation of the free flow across the weir according to: Q=Width*sqrt(g*Y*Y*Y)where Y = a*D.

Copy
public static void CalcFreeWeirFlow(
	out double qCrit,
	ref double dQdHups,
	ref double dQdHdws,
	double a,
	double d,
	double width,
	double delta
)

Parameters

qCrit
Type: SystemDouble
The critical discharge [m3/s]
dQdHups
Type: SystemDouble
Derivative of Q with respect to upstream water level [m2/s]
dQdHdws
Type: SystemDouble
Derivative of Q with respect to downstream water level [m2/s]
a
Type: SystemDouble
Coefficient
d
Type: SystemDouble
Upstream depth above sill level [m]
width
Type: SystemDouble
Width of the weir [m]
delta
Type: SystemDouble
Minimum head difference. When head difference is below this linearisation is applied
