Problem $1(15$ points$)$

Plot the conveyance curve for the channel shown in Figure $1$ below, the sides lopes of the lower portion

are $1H$:$1V.$ Determine the normal depth for a discharge of $10m\frac{3}{s}$ and bottom slope of $0\mathrm{.}002.$ Manning

coefficient is $n=0\mathrm{.}01.$

Problem $2(10$ points$)$

Determine the flow regime $($subcritical or supercritical$)$ in the channel, shown in Figure $1,$ if the slope is

$0\mathrm{.}001.$ The side slopes of the lower part of the section is $1H$:$1V.$ Manning coefficient is $n=0\mathrm{.}01.$
