Triangular notch:

Q = (8/15)*Cd*(sqrt(2g))*tan(0/2)*(H)^(5/2).

Rectangular notch:

Q= (2/3)*Cd*b*(sqrt(2g))*(H)^(3/2).

Stepped notch:

Q1= (2/3)*Cd*b1*(sqrt(2g))*(H1)^(3/2).
Q2= (2/3)*Cd*b2*(sqrt(2g))*(((H2)^(3/2))-((H1)^(3/2))).
Q=Q1+Q2+............

Trapezoidal notch:

Q=(Qtri)+(Qrect)=(8/15)*Cd*(sqrt(2g))*tan(0/2)*(H)^(5/2)
+ (2/3)*Cd*b*(sqrt(2g))*(H)^(3/2).
