the increased discharge resulting from urbanization results in significant channel changes and downstream sedimentation. The major discharge controlling channel form is bank full discharge which occurs once a year

assume prior to urbanization the bank full discharge is 2.5 m^3/s with a mean velocity of 0.95 m/s. As a result of urbanization the volume of the annual peak discharge is changed to 8.4 m^3/s with a mean velocity of 1.10 m/s

what increase in channel cross-section would be needed to accommodate this flow....and how much sediment (metric tons) would produce from 1500m stretch of channel

1 m^3 of soil weighs 1650 kg

Q = vA

Q= discharge (m^3/s)

v = velocity

A= cross-sectional area of channel
