Problem #$3$ Normal Depth $-$ Trapezoidal Channel

This problem will require the use of Excel, MATLAB, or other software $($i$.$e$.,R).$ You must attach your spreadsheets and$/$or codes for me to review.

Repeat the analysis in Problem $2$ for a trapezoidal channel, Slope $=0\mathrm{.}0001,15ft$ bottom width, and side slopes of $1($vertical component$)$ to $1\mathrm{.}5($horizontal component$).$ Hint: use Table $5\mathrm{.}1\mathrm{.}2$ for Geometric Functions for Channel Elements.

d What are differences in normal depth calculations seen comparing the rectangular and trapezoidal configuration? Which are higher$/$lower$?$
