Bridge Pier Scour Countermeasures

World Environmental and Water Resources Congress 2007, 2007
Local scour at bridge piers is a potential safety hazard to the traveling public and is a major concern for transportation agencies. Bridge pier scour is a dynamic process that varies with water depth, flow angle, pier geometry and other factors.

Applicability and limitations of time domain reflectometry bridge scour monitoring system in general field conditions

, 2020
A real-time and durable system for scour process monitoring with sufficient spatial precision is in pressing need for bridge safety management. In light of this, an innovative bundled time domain reflectometry sensing cable was recently proposed to ...

Radar measurement of bridge scour

NDT & E International, 1999
Abstract Scour around bridge piers and abutments has resulted in many structural failures over the past decade and considerable research has been carried out to develop methods which can be used to evaluate the risk of scour affecting the integrity of these major structures. Traditional site investigation methods based on borehole core and samples of

Physics-Based Assessment of Climate Change Impact on Long-Term Regional Bridge Scour Risk Using Hydrologic Modeling: Application to Lehigh River Watershed

Journal of Bridge Engineering, 2019
Climate change poses a substantial threat to civil infrastructure systems. This paper proposes a systematic approach to evaluate the climate change impact on the risk of bridge scour.

An Analysis of Relief Bridge Scour

Journal of the Hydraulics Division, 1963
Based on the proposition that the limit of clear-water scour is a boundary shear equal to the critical tractive force, analytical relationships are obtained for the scour in a long contraction, at an abutment, and around a pier. The pier and abutment solutions make use of the assumption that the flow beyond the scour hole can be ignored and that the ...

Characterization and field validation of smart rocks for bridge scour monitoring

Structural Health Monitoring, 2019
In this study, two types of smart rocks are proposed, characterized, and validated for bridge scour monitoring, including the arbitrary oriented system smart rock and the automatically pointing to south system smart rock. Effect of the smart rocks on the
