A sluice gate controls the flow in a concrete

$(n=0\mathrm{.}025)$ rectangular channel, the discharge is $10$

$\frac{m^3}{s},$ and the channel bottom slope is $0\mathrm{.}001.$ If the

channel is designed for a best hydraulic section:

Calculate the water depth just after the hydraulic

jump if the flow is uniform.

Calculate the depth of flow just upstream of the

hydraulic jump.
