A rectangular channel with bed width $($b$)$ of $5$ and Manning$$s roughness $($n$)$ of $0\mathrm{.}015)$ flows on a

slope of $1$ in $100.$ If the uniform flow depth of this channel is $1$m and the water depth at the venacontractor $($just after the gate$)$ is $0\mathrm{.}3$m$.$

$1.$ Decide slope type

$2.$ Sketch the flow profile variation along the channel and tabulate flow depth at every

changing location.

$3.$ Calculate properties of hydraulics jump$/$s

$4.$ Calculate and tabulate Es and F at each flow changing location.

$5.$ Plot, depth, Es and F variation along the channel $($Not to Scale$)$

$6.$ Calculate length of two gradually varying flow profiles
