Impact behavior of a strengthened bridge substructure under scour and vessel collision
When 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
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 ...

Development of Abutment Design Standards for Local Bridge Designs, Volume 1 of 3, Development of Design Methodology; TR-486, August 2004 [PDF]
Several superstructure design methodologies have been developed for low volume road bridges by the Iowa State University Bridge Engineering Center. However, to date no standard abutment designs have been developed.

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
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.
