‘‘Mean’ Section MethodMean’ Section Method

Q = vQ = v11*BF*(*BF*(dd0+0+dd11) + ) + (v(v11 + v + v22))*(*(dd11 + d + d22) b) b22 + + (v(v22 + v + v33))*(*(dd22 + d3 + d3) b) b33 + etc+ etc 22 2 2 22 22 22

“The total discharge (Q) is the product of the distance between verticals by the sum of the products of the mean of the depths of two adjacent verticals by the mean of the average velocities

over those two verticals “

NB: Discharge within ‘panels’ near each bank is computed after selecting a ‘Bank Factor’ (BF) on the CMC3

‘‘Bank Panel’ Velocity FactorBank Panel’ Velocity FactorApplies to ‘Mean Section’ Method onlyApplies to ‘Mean Section’ Method only

The operator will need to make a judgement, based on his/her observation to determine a factor to apply to mean velocity

measured in verticals closest to each bank and enter this factor into the CMC3, in EACH of the Water’s Edge verticals

Factor Comment

90%* Normally applied to bank panels of rectangular or square shape

66% Normally applied to triangular shape bank panels

50% Normally applied to triangular shape bank panels

33% Normally applied to triangular shape bank panels

* Based on calculation from AS3778 Part 3.1 ‘Measurement of water flow in open channels’

‘‘Mid’ Section MethodMid’ Section Method

Total Discharge = Total Discharge = VV11dd11 ( b( b11+ b+ b22)) + + VV22dd22 ( b( b2 + 2 + bb3)3) + + VV33dd33 ( b( b33+ + bb44)) etc etc

“The total discharge is the sum of the products of the average velocity in each vertical by the depth of that

vertical and by the mean width of the two panels adjacent to the vertical “

This method assumes ‘zero’ velocity within ‘panels’ near each bank
