A b$)$oad$-$crested weir is being considered for flow measurement in a long, rectangular, concrete irrigation canal. The channel is designed to convey $1022\mathrm{.}0[$cfs$]$ of water. The maximum allowed depth of flow in the $14\mathrm{.}43-ft-$wide canal is $10\mathrm{.}73[ft].$ Determine the maximum height of a flow$-$measurement weir in $[ft]$ before the backwater exceeds the maximum allowed depth, assuming ideal weir.
