Impact behavior of a strengthened bridge substructure under scour and vessel collision
Case Studies in Construction MaterialsWhen subjected to a vessel collision in the presence of scour induced by wave-current or flood, a bridge can sustain more severe damage compared to the pristine bridge undergoing the same impact.

Interacting Effects of Wood and Channel Geometry on Pool Depth in Gravel‐Bed Rivers
Earth Surface Processes and Landforms, Volume 51, Issue 10, October 2026.The river gradient and associated grain size distribution and other factors determine the relative influence of channel geometry versus wood on the resulting bed morphology. Bed morphology reflects the interaction between channel geometry and wood, suggesting that the most effective restoration to create pool habitat will consider this interaction ...

Earth Surface Processes and Landforms, Volume 51, Issue 10, October 2026.Large wood (LW) plays a key role in river dynamics and biodiversity, but quantifying its volume and budget remains challenging. This study compared in situ and UAV‐based measurements of LW jams in two Gaspé Peninsula rivers (Québec, Canada), highlighting strong variability mainly due to operator bias. A new methodology reduced this variability, leading

The Effect of Geotextile Layer in Decreasing Local Scour of Cylindrical Bridge Pier
علوم آب و خاک, 2017 Flood currents are considered threatening factors by creating local scour along bridge piers. One method for decreasing local scour is to strengthen the bed against imposed tensions.
