Fluvial Hydrodynamics: Hydrodynamic and Sediment Transport Phenomena
TL;DR: In this paper, hydrodynamic principles and Turbulence in Open Channel Flows are used to define the Sediment Threshold of a bed-load transport in a river process.
Journal ArticleDOI
Characteristics of Horseshoe Vortex in Developing Scour Holes at Piers
Subhasish Dey,Rajkumar V. Raikar +1 more
TL;DR: In this article, an experimental study on the turbulent horseshoe vortex flow within the developing (intermediate stages and equilibrium) scour holes at cylindrical piers measured by an acoustic Doppler velocimeter (ADV) is presented.
Journal ArticleDOI
Clear water scour at circular piers : a model
TL;DR: In this article, a quasi-steady vortex flow field around circular piers in a quasidequilibrium scour hole under a clear water regime has been investigated experimentally, and the main characteristic features of the flow, to be modeled, are a relatively large secondary vortex flow within the scour holes and skewed velocity distributions along the circumference of the pier.
Journal ArticleDOI
Scour Downstream of an Apron Due to Submerged Horizontal Jets
Subhasish Dey,Arindam Sarkar +1 more
TL;DR: In this article, the results of an experimental investigation on scour of noncohesive sediment beds downstream of an apron due to a submerged horizontal jet issuing from a sluice opening are presented.
Journal ArticleDOI
Time Variation of Scour at Abutments
TL;DR: In this article, a semi-empirical model is presented to compute the time variation of scour depth in an evolving scour hole at short abutments (abutment length/flow depth 1), namely the vertical wall, 45° wing wall, and semicircular, in uniform and nonuniform sediments under a clear water scour condition.
