Determination of position of hydraulic jump in a flume by using CFD and comparison with experiential results

open access: yesRomanian Journal of Ecology & Environmental Chemistry, 2020
Dams and hydraulic structures are used for the supply and control of water, which have great importance on human life. Sluice gate is one of the hydraulic control structures.

Discharge predicted in compound channels using adaptive neuro-fuzzy inference system (ANFIS)

open access: yesOpen Engineering, 2023
Some hydraulic structures and phenomena, including compound channels, must be studied in relation to open channel flow. Despite the fact that the primary channel and watersheds share a similar degree of roughness, estimating discharge in composite ...

Application correlation algorithm to create a new critical depth equation for gradually varied flow in trapezoidal channel using teaching–learning and studying [PDF]

open access: yesJournal of Hydraulic Structures, 2020
The critical depth is a hydraulic factor of the flow, it plays a particularly important role in studying and designing for open channels, especially during identification of water surfaces and analyzing to determine the phenomenon of a hydraulic jump in ...

Modelling rollers for shallow water flows [PDF]

open access: yes, 2013
Hydraulic jumps, roll waves or bores in open channel flows are often treated as singularities by hydraulicians while slowly varying shallow water flows are described by continuous solutions of the Saint-Venant equations. Richard & Gavrilyuk (J.

Extended theory of hydraulic hysteresis in open channel flow [PDF]

open access: yes, 2017
The occurrence of hysteresis in a supercritical, open-channel flow approaching an obstacle has been recognized and investigated both experimentally and theoretically over the last few decades. However, the available theory and experimental investigations

Flow structure of the confluence between an open channel and a pipe

open access: yesWater Science and Technology, 2023
It is common that the sewage is discharged into rivers through a municipal drainage network. The hydraulic properties of the confluence between a lateral drainage pipe and a rectangular open channel are investigated using numerical simulation.

Study of the relation between hydraulic jump and the flood water level in the river on the downstream of a spillway [PDF]

open access: yesMATEC Web of Conferences, 2019
Kuningan Dam which is located in Kuningan District, West Java has 21,8 km2 watershed area. This dam also acts as a flood control facility which functions supported by the reservoir’s topography and its spillway building.

Current knowledge in hydraulic jumps and related phenomena: A survey of experimental results [PDF]

open access: yes, 2009
The hydraulic jump is the sudden transition from a high-velocity open channel flow regime to a subcritical flow motion. The flow properties may be solved using continuity and momentum considerations.
