An open channel of square cross section had a flowrate of 17.2 ft³/s when first used. After extended use, the channel became 0.6-filled
with silt. Determine the flowrate for this silted condition. Assume the Manning coefficient is the same for all the surfaces.
Qs=
! ft³/s
(Manning equation) The triangular flume shown in the figure below is built to carry its design flowrate, Qo, at a depth of 0.991 m as is
indicated. If the flume is to be able to carry up to twice its design flowrate, Q = 2Qo, determine the freeboard, I, needed.
