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.

WRPMD'99, 1999
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.

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 ...

Journal of the Hydraulics Division, 1960
Relationships are proposed for prediction of scour at piers and abutments for case in which sediment is supplied to scour hole; relationships were obtained from combination of approximate analysis and laboratory experiments, and depend on knowledge of flow conditions at bridge site; studies were made at Iowa Institute of Hydraulic Research.

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.

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 ...

Circular time-domain reflectometry system for monitoring bridge scour depth
Marine georesources & geotechnology, 2020Sediment has a severe effect on bridge stability, and time-domain reflectometry (TDR) is a suitable method for assessing scour depth. This paper presents a fundamental study to demonstrate the suitability of a circular TDR system to enhance the ...
