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 ...

Estimate of void fraction and air entrainment flux in hydraulic jump using Froude number [PDF]
, 2018 Hydraulic jumps are induced in hydraulic facilities for the purposes of energy dissipation or flow aeration. Presently there is no means for a simple estimate of void fraction distribution and air entrainment flux, without detailed physical modelling ...

Steady free surface flows induced by a submerged ring source or sink
, 2012 The steady axisymmetric flow induced by a ring sink (or source) submerged in an unbounded inviscid fluid is computed and the resulting deformation of the free surface is obtained.

Withdrawal from a two-layer inviscid fluid in a duct
, 1998 The steady simultaneous withdrawal of two inviscid fluids of different densities in a duct of finite height is considered. The flow is two-dimensional, and the fluids are removed by means of a line sink at some arbitrary position within the duct.

Froude number and water residence time.
, 2019 Froude number and water residence time calculated for each sub-basin of Lake Kariba. The Froude number decreases from the first toward the fourth sub-basin, and the water residence time increases toward the fourth sub-basin.
