Investigation of The Area of Around Bridge Abutment by A-Jacks to Protect Against Scour [PDF]
علوم و مهندسی آبیاری, 2017 Scouring is a natural phenomenon that arises from the erosive action of flow field in the alluvial streams. Bridge failure caused by fully scouring of the piers and abutment makes completely clear the necessity of investigating in the case of scour ...

Journal of Hydraulic Engineering, 1985 A Froude number that is applicable to subdivisions of a cross section is developed assuming one-dimensional flow. The subdivision Froude number is shown to determine accurately the flow regime in subdivisions of a cross section. An imaginary subdivision Froude number in a floodplain indicates that the velocity is increasing with depth and that a one ...

Experimental analysis of hydraulic jump at high froude numbers [PDF]
Sādhanā, 2021 Abstract The hydraulic jump is a rapid transition state from supercritical to subcritical flow that occurs commonly in rivers, prismatic channels and downstream of spillways. In this study, the characteristics of the hydraulic jump in a stilling basin downstream of the spillway chute channel with the slopes of α = 12o and 30o were investigated ...

Theoretical Criterion for Stability of Free Hydraulic Jump on Adverse Stilling Basins [PDF]
Journal of Hydraulic Structures, 2014 Hydraulic jump on adverse stilling basin is an unstable phenomenon which causes some complexities in controlling of the jump. This paper considers the stability of free hydraulic jump on adverse stilling basins from a theoretical point of view.
