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

Pattern of channel adjustment due to bottom-block scour on the Yellow River

Shui kexue jinzhan, 2015
The paper is intended to show the patterns of the changes both in the cross section and the local flow due to a peculiar kind of scour,bottom-block scour,or named as bottom tearing scour and bottom ripping up,which is often found to occur in the forms of

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

Numerical Investigation of Local Scour Around Bridge Pile-Group Foundations Under Steady Flows

Infrastructures
Local scour around pile-group foundations is a predominant cause of hydraulic instability in bridge engineering. This study employs a fully coupled three-dimensional computational fluid dynamics model to investigate local scour around a 2 × 2 inline pile

Estimation of Local Scour Dimension below Siphon Spillway with the Ski-jump Bucket Energy Dissipater Using the Group Method of Data Handling (GMDH)

علوم آب و خاک, 2018
The investigation of local scour below hydraulic structures is so complex that makes it difficult to establish a general model to provide an accurate estimation for the local scour dimension.
