Journal of Marine Science and Engineering, 2022 This paper reviews the recent development of numerical modelling of local scour around hydraulic and marine structures. The numerical models for simulating local scour are classified into five categories: sediment transport rate models, two-phase models,

Physical Modeling of Local Scouring around Bridge Piers in Erodable Bed
Journal of King Saud University: Engineering Sciences, 2007 The construction of bridges in alluvial channels will cause a contraction in the waterway at the bridge site. The contraction in the waterway will cause a significant scour at that site.

Research on the Wing-Type Antiscour Device of Pier Based on Scour Test and Numerical Simulation
Advances in Civil Engineering, 2021 In order to reduce the local scour before the antiscour device of piers, this paper proposed an improvement on a “V-type” device. That was to say, wing plates were set on the surface of the “V-type” device to enhance the diversion and reduce the local ...

Hydrology, 2022 River bridge piers may collapse due to the local scour around their foundations. It is known that local scour is an effect of the three-dimensional flow field that develops near the pier and that the geometric complexity of a non-cylindrical pier may ...

Local scour at abutments: A review
Sadhana, 2004 Failure of bridges due to local scour has motivated many investigators to explore the causes of scouring and to predict the maximum scour depth at abutments. In this paper, a detailed review of the up-to-date work on scour at abutments is presented including all possible aspects, such as flow field, scouring process, parameters affecting scour depth ...

Ain Shams Engineering Journal, 2013 Local scour downstream stilling basins is so complex that it makes it difficult to establish a general empirical model to provide accurate estimation for scour depth. Lack estimation of local scour can endanger to stability of hydraulic structure and can

Using side flow jets as a scour countermeasure downstream of a sluice gate
Beni-Suef University Journal of Basic and Applied Sciences, 2021 Background Local scour is one of the main problems affecting the stability and operation of control hydraulic structures. Many techniques were used to control the resulting scour.

Numerical Simulation on the Local Scour Processing and Influencing Factors of Submarine Pipeline
Journal of Marine Science and Engineering, 2023 To investigate the different influencing characteristics of local scour around submarine pipelines, hydrodynamic and sediment transport two-dimensional models based on Flow-3D are used to numerically simulate the local scour around the pipeline under ...

Local scour around a bridge pier under ice-jammed flow condition – an experimental study
Journal of Hydrology and Hydromechanics, 2021 The appearance of an ice jam in a river crucially distorts local hydrodynamic conditions including water level, flow velocity, riverbed form and local scour processes.
