Consider the geometry sketched in the figure below and develop a spreadsheet to calculate the hydraulic geometry parameters, velocity, and flowrate as a function of flow depth. Assume $n=0\mathrm{.}02$ for both the main channel and the floodplain. The channel slope is $0\mathrm{.}002.$ Perform calculations for flow depths in increments of $3$ inches from $3$ inches to a maximum of $10$ ft $.$ At each flow depth, calculate the cross$-$sectional area, wetted perimeter, hydraulic radius, channel width, average flow depth, bulk velocity, and discharge. Plot each of these seven parameters as a function of the flow depth. Assume the flow is steady and uniform.
