Conclusions

  1. 1.

    An intake structure with a closed flow having a vertical axis of rotation contributes to the development of a favorable kinematic structure in the channel, which makes it possible to minimize scouring beyond the structure.

  2. 2.

    Excedence of the near-bottom average and maximum velocities above the average velocities in the channel comes about atl≤3.3hc downstream from the axis of the intake.

  3. 3.

    The magnitude of the ratio of the maximum 1st-percentile and average 50th-percentile flow velocities (v1%/v50%), which characterizes the velocity pulsation, attains values for the undisturbed flow in the near-bottom region at a distancel≥4.1hc.

  4. 4.

    Complete equalization of the plan diagram of velocities is noted at a distance (4.9–7.8)hc from the axis of the intake structure.
