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.

Simultaneous Effect of Collar and Roughness on Reducing and Controlling the Local Scour around Bridge Abutment

Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2017
Investigation of local scour around hydraulic structures particularly bridges is of crucial importance in river engineering. Bridge destruction mostly occurs as a result of scour phenomenon around piers and abutments, not because of structural weaknesses.

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.

Scour Development in Square Pile Groups: Effects of Pile Number and Spacing

Civil Engineering Dimension
Local scour around pile group foundations poses a significant risk to hydraulic and coastal structures, particularly when multiple piles interact with complex flow patterns. This study presents a numerical investigation of local scour around pile groups

Experimental study on local scour around large-diameter submerged cylinders under combined waves and current action

Shui kexue jinzhan, 2019
The characteristics of local scour around large-diameter submerged cylinders are quite different from the non-submerged ones under combined wave and current conditions. Local scour model tests are carried out in a wave-current flume. A submerged cylinder

Investigating the effect of curved shape of bridge abutment provided with collar on local scour, experimentally and numerically

Ain Shams Engineering Journal, 2015
Scour around bridge supports such as abutments can result in structural collapse and loss of life and property, so there is a need to control and minimize the local scour depth.

LOCAL SCOUR AMD CURRENT AROUND A POROUS BREAKWATER

Coastal Engineering Proceedings, 1976
Scour at the foot of vertical homogeneous crib style walls which were used as models for detached breakwaters, and the rise of mean water level in the shoreside region of the breakwaters were experimentally investigated, and the experimental results were compared to some field data.

Wave–Current Force Characteristics of Monopile Foundations on Scoured Seabeds

Journal of Marine Science and Engineering
Local scour around offshore wind turbine foundations is a common engineering challenge. It changes the hydrodynamic loads and affects the foundation’s load-bearing capacity.

SIMULATION OF SCOURING AROUND A VERTICAL CYLINDER DUE TO TSUNAMI [PDF]

Science of Tsunami Hazards, 2017
* Corresponding author radianta@ugm.ac.id ABSTRACT Local scour due to tsunami is damaging especially on shallow foundation. Although relatively in a short duration, tsunami attack may scour material around buildings that led to destruction. A number of
