Previous experimental research on utilizing pier modifications as countermeasures against
local scour has focused primarily on circular pier. It is of utmost importance to further …

Accumulations of large woody debris can worsen scour at a bridge pier and thereby lead to
structural damage. Accumulations can also increase the flood risk in adjacent areas. These …

Extreme flood flows in rivers and the floating debris they carry have the potential to generate
significant impact forces on bridges spanning the watercourse. Recent flood events have …

This paper analyzes the influence of the geometry of bridge piers and supplied debris on the
formation and growth of wood debris jams at bridge piers. A total of 162 laboratory …

The accumulation of large woody debris (LWD) at bridge piers is a serious hazard to the
structural integrity of bridges across watercourses worldwide. The exacerbated scour that …

The mechanism of bridge pier scour becomes more complex in the presence of debris
accumulation upstream of the pier. While using countermeasures may be effective in …

This paper presents the results of comprehensive laboratory experiments to investigate the
effects of hooked-collar on the scour development around a vertical pier with a lenticular …

Bridge pier scouring is a significant concern in hydraulic engineering, requiring thorough
investigation under various conditions to estimate maximum scour depth and mitigate the …

In order to obtain an adequate understanding of the vulnerability of historical multi-span
masonry bridges during flood hazards for the better conservation, a typical multi-span stone …

A woody debris jam around a bridge pier causes a change in flow structure and results in
additional scour and an increase in the hydraulic head upstream of the pier, threatening its …
