Assessment of the structure and function of natural hydraulic jumps. For each increase in F1, the longitu- dinal location of the jump must also be maintained by adjusting a downstream sluice gate Rajaratnam, ; Pasternack et al.

University of California, Berkeley, 75 pp, 3 appendices. Discussion [26] Air concentrations for the submerged jump and sloping jump generally differed from the CHJ data of Resch [28] Our results suggest air concentrations can be signif- and Leutheusser [] and Chanson and Brattberg [] icant and vary greatly in bedrock channels.

This research on natural hydraulic jumps and Comparatively, the most hydraulic efficient sloping hydraulic jets provides new insight into these ubiquitous jump is the A-jump Vischer and Hager, Classification of sloping gradually varied outflow, and the downstream tailwater jumps depends on the location of the jump relative to the Fig.

While submerged jump air concentrations were ratory research, air concentrations were skewed with similar to CHJ air concentrations of Resch and Leutheusser submergence of the jump roller beneath the free surface [] for both Froude conditions, CHJ air concentrations [Rajaratnam, ; Hager, ].Air in Natural Hydraulic Jumps.

Small Step Mapping. Maping and digital elevation modeling of small natural steps. High-resolution digital elevation models (DEMs) for natural submerged and unsubmerged jump regions were tested against the classical hydraulic jump (CHJ) and engineering analogues that have dominated previous geomorphic and engineering research.

All types of submerged hydraulic jumps according to classification of Chow were investigated. Sixty runs had been conducted including 10 runs with flat apron which was taken as a comparison case.


Sixty runs had been conducted including 10 runs with flat apron which was taken as a comparison case. While this analogue has been applied to unsubmerged jumps of varying sizes in natural channels [e.g., Kieffer, ; Carling, ], it has also been applied to submerged jumps in step‐pool settings [e.g., Parker and Izumi, ].
