Abstract: In this laboratory research the free surface profiles of a rather complex hydraulic jump, which is created at a sluice gate within a straight rectangular-but non prismatic-inclined channel are examined, analyzed and discussed. The channel is abruptly expanding at the sluice gate location and the created flow separation is dominant, fully affecting these profiles. The experimental Froude number range is rather small, the channel expansion ratio varies between0.50 and 0.85, while the inclination channel angles are changing between 0° and 8°. The profiles are also compared to corresponding profiles in prismatic inclined channels: When the expansion ratio approaches unity the jump profiles approach corresponding profiles in prismatic channels.
