Abstract: An experimental investigation was performed to determine the critical conditions for displacement of riprap placed on streambeds surrounding bridge piers. A functional relation between stability number, a dimensionless ...

Abstract: Seepage can be an important cause of failure in riprap revetments, especially on streambanks consisting of layered alluvium, and on stage-controlled rivers. Revetments can be protected against seepage by filters designed ...

Abstract: Retention of pools to allow navigation has produced a characteristic, anomalous topography on a number of rivers (e.g., Ohio, Illinois, Kanawha). A gently sloping subaqueous bench at and just below minimum pool stage has ...

Abstract: A method for predicting the effect of rectangular foundation geometry on local scour around bridge piers is presented using existing scour equations and considering the mechanisms of local scour. Normalized scour depths ...
