$.(20$ pts$)$ A canal drop structure is constructed as a concrete rectangular channel $5$ feet in width with a Manning$$s n of $0\mathrm{.}015.$ The drop is in uniform flow and has bed slope is $0\mathrm{.}09$ ft$/$ft$.$ The canal design flow rate is $65$ ft$3/$s$.$ At the bottom of the drop the rectangular canal bed is horizontal.

a$.$ What classification of hydraulic jump would occur at the bottom of the drop? Why?

b$.$ What would be the flow depth downstream of the hydraulic jump?

c$.$ What is the estimated energy loss in the hydraulic jump?

d$.$ What are two estimates of the hydraulic jump length using:

$$ i$.$ Safranez equation

$$ ii$.$ Bakhmetef equation
