A very long rectangular channel (Figure P10.54) has normal flow conditions at locations A and C, and a change in the bottom slope occurs at location B.

(a) Somewhere between locations A and C a hydraulic jump will take place. Explain why this statement is true.

(b) Classify and sketch the two possible water surface profiles that exist between locations A and C.

(c) By appropriate reasoning and calculation, determine whether the jump will occur upstream of location B, or downstream of location B.
