A trapezoidal channel with a bottom width of 10 m carries a flow of 1000 m/s. The side slope z = 2, Manning's n is 0.02, and the along channel slope is 0.005. Just downstream of a bridge crossing the depth is 7 m. Determine the depth of flow for the next 500 m downstream using the standard step method.

Question
A trapezoidal channel with a bottom width of 10 m carries a
flow of 1000 m'/s. The side slope z = 2, Manning's n is 0.02,
and the along channel slope is 0.005. Just downstream of a
bridge crossing the depth is 7 m. Determine the depth of flow
for the next 500 m downstream using the standard step method.
Plot y(x) and submit your spreadsheet.
