Prediction of scour depth around bridge abutments using ensemble machine learning models
Neural computing & applications (Print), 2023 Abutments are the structures that support the ends of a bridge deck. Scouring of streambed is a significant problem and ultimately results in the failure of the bridge when the abutments are exposed to flowing water over the long term.

Checking the Accuracy of Selected Formulae for both Clear Water and Live Bed Bridge Scour
Journal of Engineering, 2023 Due to severe scouring, many bridges failed worldwide. Therefore, the safety of the existing bridge (after contrition) mainly depends on the continuous monitoring of local scour at the substructure.

Mechanical plaque removal in step‐1 of care
Periodontology 2000, EarlyView., 2023 Abstract Maintaining a regular oral hygiene routine is essential for taking care of our mouths, ensuring healthy teeth, and achieving fresh breath. Patient education on oral hygiene is an important component of their overall treatment. Firstly, patients should be informed about the direct connection between bacteria in dental plaque and oral diseases ...

Local scour around a bridge pier under ice-jammed flow condition – an experimental study
Journal of Hydrology and Hydromechanics, 2021 The appearance of an ice jam in a river crucially distorts local hydrodynamic conditions including water level, flow velocity, riverbed form and local scour processes.

Risk-based bridge scour management: A survey
, 2021 Scour is a major cause of bridge failure and results in significant economic losses through disruption to operation. This phenomenon naturally affects bridges with underwater foundations and is exacerbated during high river and/or turbulent flows (e.g. due to extreme events).

Structural Health Monitoring for Performance Assessment of Bridges under Flooding and Seismic Actions [PDF]
, 2018 Bridges can be subjected to damaging environmental actions due to flooding and seismic hazards. Flood actions that result in scour are a leading cause of bridge failure, while seismic actions that induce lateral forces may lead to high ductility demand ...

Predicting maximum scour depth around bridge abutment using M5 model [PDF]
علوم و مهندسی آبیاری, 2018 Scour around piers and abutments leads to a lot of bridge failures. Scouring around the bridge piers and abutments is one of the most important factors in bridge failure which happens over time and increases during floods, probably causing general damage

Estimation of Scour Depth at Bridge Piers by Using FASTER Model and Experimental Formulas [PDF]
مهندسی منابع آب, 2017 Bridges are one of the most important river structures. One of the main causes of bridge failure is local scour at bridge piers. Yearly, Many bridges failed around the world because of disregarding hydraulic factors.
