feet per second $($cfs$).$ The slope of the channel is So $=0\mathrm{.}006$ ft$/$ft$.$

a$)$ Determine the normal depth of flow y o in feet.

b$)$ Determine the critical depth yc in feet.

c$)$ Determine the critical slope Sc$.$

d$)$ Considering So and Sc as well as y o and y c$,$ classify the bed slope of the channel.

e$)$ Determine the width b of the channel in feet.

f$)$ Determine the cross$-$sectional area A of the flow in ft $2.$

g$)$ Determine the velocity v in feet per second $($fps$).$

h$)$ Determine a suitable depth of freeboard and the height for the channel sidewalls in feet
