Estimation of scour for bridges in Illinois [PDF]
Scour and Erosion, 2016 Scour development around bridge piers is one of the main reasons for bridge failure. This paper presents the comparison of ultimate pier and contraction scour depth for cohesive soils at nine bridge sites in Illinois. Results obtained from common prediction methods such as SRICOS, Hydraulic Engineering Circular No.

Vulnerability of bridges to scour: insights from an international expert elicitation workshop [PDF]
Natural Hazards and Earth System Sciences, 2017 Scour (localised erosion) during flood events is one of the most significant threats to bridges over rivers and estuaries, and has been the cause of numerous bridge failures, with damaging consequences.

Study of the time-dependent clear water scour around circular bridge piers
Journal of Hydrology and Hydromechanics, 2017 The local scour around bridge piers influences their stabilities and plays a key role in the bridge failures. The estimation of the maximum possible scour depth around bridge piers is an important step in the design of the bridge pier foundations.

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 ...

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).

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.

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.

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.
