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.

Bridge Pier Scour Countermeasures
World Environmental and Water Resources Congress 2007, 2007Local 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.

Radar measurement of bridge scour
NDT & E International, 1999Abstract 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

An Analysis of Relief Bridge Scour
Journal of the Hydraulics Division, 1963Based 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 ...

Local Scour at Bridge Abutments
Journal of Hydraulic Engineering, 1992Laboratory data for local scour depth at bridge abutments are presented. These include sufficient data to demonstrate the effects on scour depth of abutment length, flow depth, and abutment shape and alignment. In addition, some data for the effects of sediment characteristics, flow intensity, and approach channel geometry are given.

Scour Protection at Bridge Piers
Journal of Hydraulic Engineering, 1992The objective of this study is to review existing methods and propose alternative or additional devices for scour protection around bridge piers. Engineering methods used in dealing with pier‐scour problems include placing coarse riprap around the foundations. An inverted filter layer is normally placed beneath the riprap to overcome leaching problems.
