Water flows uniformly at a depth of \(1 \mathrm{~m}\) in a channel that is \(5 \mathrm{~m}\) wide as shown in Fig. P10.63. Further downstream, the channel cross section changes to that of a square of width and height \(b\). Determine the value of \(b\) if the two portions of this channel are made of the same material and are constructed with the same bottom slope.
