A culvert is built in a trapezoidal channel with bed width of 1.8 (m) and side slopes of 2H: 1V. The slope of the channel is 0.002 (m/m). Manning roughness coefficient for the channel is 0.025. The length of the culvert is 20 (m). (a) Calculate the normal depth of the channel for a 10% AEP flow of 3.4 (m³/s). (b) (c) (20% weighting) Calculate the number of 0.9 (m) diameter pipe culverts needed to convey 10% AEP flow of 3.4 (m³/s). Inlet of the culvert system can be classified as square edge with headwalls. The culvert is placed at same slope as the channel slope. Culvert crown is 1.75 (m) above the upstream invert of the culvert and the freeboard is 0.4 (m). (30% weighting) Check whether the culvert is overtopped or not for a 5% AEP storm event with a peak discharge of 5.4 (m³/s). Refer to attachments for additional information needed for calculations.
