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.

Numerical Investigation of Local Scour Around Double Triangular Prisms Using a DBM–LBM Coupled Model
Journal of Marine Science and EngineeringLocal scour is a typical hydro-sediment coupled process around near-bed obstacles. Its intensity and spatial distribution are jointly controlled by the surrounding-flow structure, sediment transport, and bed-feedback deformation.

Scour-inducing flow around gravity anchors astride pipelines in currents
, 2014 This study simulated steady currents travelling past gravity anchors astride pipelines wallmounted on an immobile bed. Three-dimensional governing equations were solved with a Petrov–Galerkin finite element method.

Influence of flow unsteadiness on local scour at bridge piers: An energy-based perspective
International Journal of Sediment ResearchLocal scour at piers is a major cause of bridge failures worldwide. While most existing studies assume steady flow conditions, actual flood events are inherently unsteady, with distinct rising and falling limbs that significantly modify scour dynamics ...

Temporal variation of clear-water scour at compound Abutments
Ain Shams Engineering Journal, 2016 Most of actual abutments in rivers are built on foundation, while there is limited number of study available on the effects of the foundation on the local scour.

On local scour around spur dikes
, 2000 Estimation of possible maximal scour depth around the head of spur dikes is an important step in the design of spur dikes foundation. This paper briefly analyses the characteristics of flow pattern and the complex eddy structure near the head of the spur

The Effect of Geotextile Layer in Decreasing Local Scour of Cylindrical Bridge Pier
علوم آب و خاک, 2017 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.

Experimental Investigation of Scour Around Tripod Foundations Under Steady Current
Journal of Marine Science and EngineeringScour around a tripod foundation under a steady current is investigated experimentally. Experiments are conducted on three tripod foundation models and three flow-angle-of-attack conditions. The three tripod foundations differ only in the size of the top

Hazards due to large wood accumulations: Local scour and backwater rise
E3S Web of Conferences, 2018 Large wood (LW) in rivers increases the flow variability and provides habitats for various species. During flood events, transported logs can accumulate at river infrastructures and increase the flood hazard.
