Abstract: This study presents findings from two-dimensional depth-averaged flow models used to investigate distributions of flow velocity, unit discharge, and boundary shear stress associated with flow around spill-through bridge ...

Abstract: Laboratory tests using a large-scale model of a spill-through bridge abutment led to important findings about the performance of a riprap apron as an abutment scour countermeasure. Riprap stone is widely used for protecting ...

Abstract: This paper presents observations and data from a sequence of laboratory experiments conducted to evaluate geobags as a countermeasure to protect bridge-abutment foundations from failure attributable to scour of the ...
