$(15$ pts$)$ Plot the channel bottom, Hydraulic Grade Line $($HGL$)$ and Energy Grade Line $($EGL$)$ for a $1000-$foot length $($reach$)$ of $7-$foot$-$wide concrete rectangular canal conveying $70f\frac{t^3}{sec}$ based on the following field measured $($surveyed$)$ parameters:

Upstream Section #$1$

Channel Bottom Elev. $=102\mathrm{.}5$ feet

Flow Depth $=1\mathrm{.}8$ feet

Downstream Section #$2$

Channel Bottom Elev. $=100$ feet

Flow Depth $=3\mathrm{.}3$ feet

What can you tell about the flow regime based on the plot?
