A uniform flow occurs in a long rectangular channel :with the following information

Normal depth: $5$ meters

Channel slope: $0\mathrm{.}008$

Bottom width: $6$ meter

Manning $n=0\mathrm{.}015$

:Calculate the following

The flowrate $.1$

The critical depth $\mathrm{.}2$

The critical slope $\mathrm{.}3$

The size of hump necessary to create critical depth $\mathrm{.}4$

over the hump

The width of the narrowed section necessary to $\mathrm{.}5$ create minimum specific energy over the narrowed

section

The alternate depth to the normal depth $\mathrm{.}6$

Is the flow subcritical or supercritical $\mathrm{.}7$
