Water flows at $36$ ft$3/$s

through the $4-$ft

$-$wide rectangular channel.

$($Figure $1)$

Figure$1$ of $1$

The figure shows a water flow along a horizontal surface. Up the stream, the water flows at a constant depth of $1$ foot. Then, the flow depth increases within some region. After this region, the water flows at constant depth y subscript $2.$
