NODE 04 - WEIR CALC - cul de sac overland flow path GAP FLOW
QUDM Section 5.10.4
Parameters:
Length sige + (L1) = Pe (nm)
‘Water over inlet (h) = ZA (m)
Blockage Factor a
Therefore Qy= (UIUGIBESTATENNN
WEIR LEVEL(RL)
WATER LEVEL (RL)
PMT LEVEL (RL)
FREEBOARD(m) MIN REQUIRED TO PMT = 0.075m
Weir Flow Conditions:
Qg = 0.5 x 1.66 L.h??
Where Qg = Flow into field inlet (m*/s)
0.5 = blockage factor (typ)
1.66 = weir coefficient
L = weir length (m) [= 2 x {L1+L2}]
h = depth of water over inlet
