Simulation of Scour at Bridge Supports
Građevinar, 2020 Groups of piers are used on bridges to minimise scour around bridge supports. The prediction of scour around piers due to interaction of vortices around bridge piers is more complex compared to scour prediction around a single pier.

, 2021 This study addresses a key issue that prevents the wide application of the novel predominant natural frequency (PNF)‐based method for bridge scour monitoring, which is also applicable to the frequency‐based health monitoring of other structures with soil–

A comparative study of scour around various shaped bridge pier
Engineering Research Express, 2023 The study of scouring around bridge piers is very significant and plays a very important role in the safe and economical design of bridge piers. The term scouring is a process by which bed particles around the periphery of the pier get eroded and removed

Scour Reduction around Bridge Pier Using the Airfoil-Shaped Collar
Hydrology, 2023 Scouring around the bridge pier is a natural and complex phenomenon that results in bridge failure. Failure of bridges have potential devastation and public safety and economic loss, which lead to political consequences and environmental impacts ...

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).

Modelling of clear water scour depth around bridge piers using M5 tree and ANN-PSO
AQUA — Water Infrastructure, Ecosystems and Society, 2023 Scouring refers to the process by which bed sediment in a river is eroded around the periphery of a bridge abutment or pier. Many empirical models are available to estimate the scour depth for different flow, geometry, and bed roughness condition ...

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.

Clear Water Scour at Rectangular Bridge Pier with Collar [PDF]
Port Said Engineering Research Journal, 2023 Scour is the most significant threat to waterways because it leads to the failure of bridge piers and other structural components. When a collar is put in place around the pier to lessen the direct effect of the downflow on the streambed, the maximum ...

Prediction of local scour depth around bridge piers: modelling based on machine learning approaches
Engineering Research Express, 2023 Scouring is a threat to the foundations of bridges, and it frequently results in bridge collapse. Recently, machine-learning approaches have become quite popular in solving hydraulic and hydrologic problems. The present study adopted adaptive neuro-fuzzy
