Scour and Erosion, 2016
Bridge scour protection appears to be increasingly needed to protect foundations from more extreme flooding events. However, the invert level at which the protection is installed can have a significant effect upon flow through bridges and associated flooding levels (Figs. 1 & 2).

Scour and scour countermeasures at bridge sites
Transactions of Tianjin University, 2008This paper examines scour and scour countermeasures at bridge piers and abutments. Abutment scour is by far more complex than its counterpart associated with piers because of the possibility of the presence of a floodplain. Notwithstanding this, the mechanism of scour at both piers and abutments is very similar; moreover, the failure mechanisms ...

Scour Vulnerability of River Bridge Piers
Journal of Geotechnical and Geoenvironmental Engineering, 2003A simple procedure is proposed to assess the vulnerability of bridge piers in rivers, taking into account the phenomena governing fluvial dynamics during flood events. The procedure requires an estimation of the maximum scour depth of the soil surrounding both the pier and the foundation as well as an analysis of the bearing capacity of the pier ...

In 1995, the Kentucky Transportation Cabinet (KYTC) started working with Ogden Environmental and Energy Services (Ogden) to establish a risk assessment approach to analyze bridge scour. This program integrated the best ideas from other state scour programs, and the experiences of KYTC and Ogden.

Proceedings of the Institution of Civil Engineers - Forensic Engineering, 2012
In recent years there have been several bridge collapses in the United Kingdom and Republic of Ireland that have been caused by scour. Towns in the north west of England have been cut off and loss of life occurred. Major railway lines have been closed for extended periods.

Probabilistic Bridge Scour Estimates
Journal of Hydraulic Engineering, 1998Scour at bridges is generally estimated as a deterministic value. Other loads at bridges, such as vessel impact and wind loads, are determined as probabilistic values. In an effort to use probabilistic estimates as a tool in decision making, a probabilistic framework was developed for estimating scour using deterministic methods given in the Hydraulic ...

Local and Contraction Scour at Bridge Abutments
Building Partnerships, 2000In most experimental studies on erosion at bridge piers and abutments, the value of the blockage ratio b/B between the transversal obstacle dimension and the flume width is kept as small as possible (typically b/B b is not small compared to B so that the average acceleration due to contraction is expected to increase the scour effects of the ...

Bridge’s Scour Monitoring System
2014The scour of pier in riverbed is one of the major causes for bridge failure. The riverbed around the pier footing can be eroded in scouring event. Erosion of soil around the bridge foundation could lead to problems from instability of substructure to complete bridge failures.

Building Partnerships, 2000
Most empirical, local scour prediction equations over predict scour depths at structures that are wide compared to the water depths where they are located. This paper discusses various researchers attempts to deal with this problem. The methods and equations used by several Western European Countries (obtained during the FHWA, 1998 European Scanning ...
