ABSTRACT
Downstream of the sluice the position of the hydraulic jump between the M3 and M2 profiles is determined in a similar manner.
Channel 2. Providing that the depth at the sluice is not greatly in excess of the critical, a control point is to be found at r, the transition from subcritical to supercritical flow. A hydraulic jump thus links the SI and S2 profiles at a point s' where the upper profile is at sequent depth.
