The discharge in a rectangular channel of width $5$ m and maximum depth $2$ m is $10$ m$3/$sec$.$ The normal depth of the flow is $1\mathrm{.}25$ m$.$A hump of $=0\mathrm{.}2$ m is installed across the $1$ m channel bed in the downstream of the channel.$$

Check whether the hump is sufficient to make the flow reach critical state considering maximum depth of flow in the upstream of the channel.

Determine the depth of flow downstream of a section considering maximum depth of flow in the upstream of the channel.
