Determine flow depth using manning equation
WebStep 4 Calculate the total gutter flow using the equation: Q = Qs/(1 - Eo) (11.6) Where: Q = gutter flow rate, m3/s Qs = flow capacity of the gutter section above the depressed section, m 3/s Eo = ratio of frontal flow to total gutter flow (Qw/Q) (Q = 0.085 / (1-0.46) = 0.157 m3/s) Step 5 Calculate the gutter flow in width (W), using equation 11.5. Webknown, the depth of water in the gutter at the curb (see Figure 2) can be calculated: d = T × S x, ft (Equation 4A-6_2). where: d = Depth at curb for allowable spread, ft (see Figure 4). T = Spread, ft. S x = Pavement cross slope, ft/ft. Manning’s equation (modified for triangular gutter flow) is used to determine gutter flow: Q = L 7 7 x u ...
