Physical Modeling of Local Scouring around Bridge Piers in Erodable Bed
Journal of King Saud University: Engineering Sciences, 2007 The construction of bridges in alluvial channels will cause a contraction in the waterway at the bridge site. The contraction in the waterway will cause a significant scour at that site.

Influence of scour depth and flow velocity field on large-diameter pier group pile foundations
Frontiers in Marine ScienceSea-crossing bridges face critical challenges due to scour, which can destabilize foundations. This study investigates the scour characteristics of the large-diameter main pier of the Haiwen Bridge, with a pile diameter of 4.3 meters. Seabed changes were

Calculation of foundation scour for new debris flow grille dam with ground anchor and counterfort
Yantu gongcheng xuebao, 2018 The foundation play a significant role in the reliability of debris flow grille dam. Compared with the exposed structures, foundation scour under debris flows is more important. On the basis of a new proposed debris flow grille dam with ground anchor and
