A
Upstream
4
Q
Energy dissipation ratio:
A
ELOSS/ E 1
5
Q
Head Water for Outlet Control:
HW = ___ + ho - ___
Where ho = max [ TW , D + yc / 2]
A
Head Water for Outlet Control:
HW = H+ ho - LS
Where ho = max [ TW , D + yc / 2]
(The last checks for whether water is above crown of pipe)
6
Q

Yc = ______
A
Yc = (q^2 / g) ^ 1/3
(Divides flow by channel width)
