Question

- You are using the direct step method to calculate an M2 curve going from the downstream conjugate depth of a hydraulic jump to the critical depth at a free outflow. Where do you begin computation?

the hydraulic jump

the free outflow

- In gradually varied flow, the flow profile can decrease from the gate opening of a sluice gate to the upstream conjugate depth of a hydraulic jump.

True

False

- Consider a steep reach entering into a mild reach. The upstream conjugate depth pair to the normal depth in the mild reach is equal to the normal depth of the steep reach. Where does your hydraulic jump occur?

mild reach

steep reach

transition between the two reaches
