ENGINEERING HYDRAULICS

c) An old railway line near Nsawam was drain by weed over-grown winding
earth channel roughly 0.8m wide and with bank slope of about 1:16. The
4
channel is long and shallow, with a bed slope of about 0.1mm/m and only
400mm deep at the lowest point. Engineers estimate the channel will need
to convey a flow of about 0.23m/s in a five-year storm, to avoid creating a
drainage problem when the lines reopen next year. Does the channel have
sufficient capacity or will it need to be used and re-lined?
