Estimation of maximum scour depth near a spur dike [PDF]
Canadian Journal of Civil Engineering, 2016 Scour is a natural phenomenon in rivers caused by the erosive action of the flowing water on the bed and banks. Spur dikes are constructed across the flow to protect the bank from erosion by shifting of the river away from the bank. The spur dike undermines due to river-bed erosion and scouring, which is generally recognized as the main cause of spur ...

Effect of ice cover roughness on local scour around bridge piers [PDF]
Scientific ReportsIn cold-region rivers, the formation of ice cover during winter markedly modifies the hydraulic conditions, leading to enhanced local scour around in-stream infrastructures such as bridge piers. To analyze the flow characteristics and maximum local scour

Riprap mitigation of downstream scour at grade-control structures considering tailwater depth and layer thickness [PDF]
Scientific ReportsDownstream scour at grade-control structures (GCSs) poses a serious threat to structural stability and riverbed integrity. Among various countermeasures, riprap has long been recognized as a cost-effective and readily available solution for scour ...

Prediction of maximum scour depth in river bends by the Stacking model
Journal of Hydroinformatics, 2023 Abstract The accurate prediction of maximum erosion depth in riverbeds is crucial for early protection of bank slopes. In this study, K-means clustering analysis was used for outlier identification and feature selection, resulting in Plan 1 with six influential features.

Multi-approach analysis of maximum riverbed scour depth above subway tunnel
Water Science and Engineering, 2010 When subway tunnels are routed underneath rivers, riverbed scour may expose the structure, with potentially severe consequences. Thus, it is important to identify the maximum scour depth to ensure that the designed buried depth is adequate.

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 ...

Investigation of using sill under gate as a scour countermeasure downstream of a sluice gate [PDF]
The Egyptian International Journal of Engineering Sciences and Technology, 2023 Scour is a natural phenomenon caused by the removal of silt from alluvial beds caused by a stream's erosion, which happens around or next to moving water structures.

Scour features of sea-crossing bridge piers
Shuili Shuiyun Gongcheng Xuebao, 2021 The local scour around bridge piers is one of the main safety influence factors of sea-crossing bridges in the nearshore region. Based on the survey data of six bridge piers of Jintang Sea-Crossing Bridge in Hangzhou Bay during 2014, 2015 and 2017, the ...

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.

Mean Flow Structure and Local Scour around Single and Two-Column Bridge Piers [PDF]
علوم و مهندسی آبیاری, 2019 Bridges constructed across rivers are among the most important structures, especially during and after flood events. Bridge piers are exposed to some hazardous factors such as local and contraction scour hydrodynamics.
