Flow pattern formed over steps at a low-head dam: Salmon River Dam

open access: yesWater Science, 2023
Building Stepping way over the low-head dams has been proposed to reduce the risk of drowning in submerged flow conditions. In the Salmon Barrier, adding two steps downstream of weir was previously suggested as an effective method for reducing the risk ...

Experimental Investigation of the Effect of Submerged Cubic Obstacles on The Transverse Wave In A Rectangular Channel [PDF]

open access: yesعلوم و مهندسی آبیاری, 1970
Vortex is created when flow possed a group of obstacles such as bridges piers, docks and etc. Transverse wave is created by overlapping the vortex that created behind obstacles and due to adapting of the vortexes frequency with natural frequency, of ...

A NOTE ON STEADY FLOW INTO A SUBMERGED POINT SINK [PDF]

open access: yesThe ANZIAM Journal, 2014
AbstractThe steady, axisymmetric flow induced by a point sink (or source) submerged in an unbounded inviscid fluid is computed. The resulting deformation of the free surface is obtained, and a limit of steady solutions is found that is quite different to those obtained in past work.
