Hydraulic jumps can be seen in both a stationary form, which is known as a "hydraulic jump", and a dynamic or moving form, which is known as a positive surge or "hydraulic jump in translation". [16] They can be described using the same analytic approaches and are simply variants of a single phenomenon.
Hydraulic jump in a rectangular channel, also known as classical jump, is a natural phenomenon that occurs whenever flow changes from supercritical to subcritical flow. In this transition, the water surface rises abruptly, surface rollers are formed, intense mixing occurs, air is entrained, and often a large amount of energy is dissipated.
Hydraulic jets and hydraulic jumps at the toe of a falls can generate large forces to erode the bed, [14] especially when forces are amplified by water-borne sediment. Horseshoe-shaped falls focus the erosion to a central point, also enhancing riverbed change below a waterfall. [15]
The depth changes abruptly over a comparatively short distance. Rapidly varied flow is known as a local phenomenon. Examples are the hydraulic jump and the hydraulic drop. Gradually-varied flow. The depth changes over a long distance. Continuous flow. The discharge is constant throughout the reach of the channel under consideration. This is ...

Second, at the base of a spillway, a flip bucket can create a hydraulic jump and deflect water upwards. Ski jump. A ski jump can direct water horizontally and eventually down into a plunge pool, or two ski jumps can direct their water discharges to collide with one another. [5] [23] Stilling basin
Pfaadt’s 22.1 K-BB% after the All-Star break would’ve ranked sixth-best among starters for the season. His 29.4% CSW ranked top 15 in the second half, one spot behind Paul Skenes.
