Multi-Hazard Assessment of RC Bridges using Unmanned Aerial Vehicle-Based Measurements

open access: yesThe Baltic Journal of Road and Bridge Engineering, 2018
The structural performance of reinforced concrete bridges is crucial regarding the bridge safety. Monitoring the bridge performance under multihazard effects such as scour, and earthquake becomes even more important. Thus, the scour depth along the piers

Research on Identification Method of Scour Depth for Bridge Based on ERA and SVM

open access: yesShock and Vibration, 2015
A new damage identification method for bridge scour was proposed, in the case that it was difficult to detect bridge scour depth applying testing equipment.

Numerical Investigation of Flow and Scour around Complex Bridge Piers in Wind–Wave–Current Conditions

open access: yesJournal of Marine Science and Engineering, 2023
A sea-crossing bridge is typically constructed in a marine environment with complex piers, and is susceptible to severe scour at the foundation. This study presents a numerical investigation on flow and scour around a complex pier, specifically focusing ...

Clear Water Scour at Rectangular Bridge Pier with Collar [PDF]

open access: yesPort Said Engineering Research Journal, 2023
Scour is the most significant threat to waterways because it leads to the failure of bridge piers and other structural components. When a collar is put in place around the pier to lessen the direct effect of the downflow on the streambed, the maximum ...

Numerical modelling of erosion and sedimentation around offshore pipelines [PDF]

open access: yes, 1990
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

open access: yesJournal 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.

The Applicability of Time-Integrated Unit Stream Power for Estimating Bridge Pier Scour Using Noncontact Methods in a Gravel-Bed River

open access: yesRemote Sensing, 2022
In near-field remote sensing, noncontact methods (radars) that measure stage and surface water velocity have the potential to supplement traditional bridge scour monitoring tools because they are safer to access and are less likely to be damaged compared

Local Scour of Bridge Pier Sited on a Multi-Layered Sedimentary Bed in Rivers [PDF]

open access: yesE3S Web of Conferences, 2020
The riverbeds or sea beds are usually composed of multi-layers of sediments. The scour around bridge piers sited on such beds is vital to the bridge safety, but is still very difficult to be predicated as its complicated interaction between the flow and ...

Extremes in dune preservation: controls on the completeness of fluvial deposits [PDF]

open access: yes, 2015
Understanding sedimentary preservation underpins our ability to interpret the ancient sedimentary record and reconstruct palaeoenvironments and palaeoclimates.

Experimental investigation of local scour around multi-vents bridge piers

open access: yesAlexandria Engineering Journal, 2015
The harmful effect of local scour around bridge piers and abutments can induce high maintenance costs or even bridge collapse resulting in the disturbance of traffic and possibly human losses.
