A triangular channel has a top width of $3$ m$,$ a normal flow depth of $3$ m$,$ and a side slope of$1$:$1($vertical to horizontal$).$ The bed slope is $0\mathrm{.}005$ and the Manning roughness coefficient of the channel is $0\mathrm{.}03.$ Determine the velocity V in m$/$s $($to $2$ decimal points$).$
