Scour causes the erosion of soil, changes the seismic response of site, and also influences the seismic properties of bridge. To investigate the dynamic behavior and damage potential of pile-supported bridges at local scour site, the effects of scour on ...

Clean Cut is a multimodal, adaptive, checklist‐based infection prevention programme designed to improve compliance with six critical perioperative infection prevention practices. After introducing the programme at five hospitals in Ethiopia, compliance with critical infection prevention standards significantly improved and the relative risk of ...

A local scour prediction method for pile caps in complex piers [PDF]
The outcomes of an experimental study on local scour at a pile cap are presented. Experiments were conducted with the approaching flow having an undisturbed flow depth and a threshold flow velocity.

Research on the Wing-Type Antiscour Device of Pier Based on Scour Test and Numerical Simulation
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 ...

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 ...

Numerical modelling of erosion and sedimentation around offshore pipelines [PDF]
In this paper a numerical model is presented for the description of the erosion and sedimentation near pipelines on the sea bottom. The model is based on the Navier-Stokes equations and the equation of motion and continuity of sediment.\ud \ud The ...

Physical Modeling of Local Scouring around Bridge Piers in Erodable Bed
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.

Using side flow jets as a scour countermeasure downstream of a sluice gate
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
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 ...
