In this research, dual submerged vanes have been installed in various arrangements to
reduce the bridge pier scour. The analysis results achieved from the FLOW-3D numerical …

Introduction The construction of hydraulic structures such as bridge piers in river beds
changes the hydrodynamics of the flow and is associated with the scouring phenomenon …

Scouring threaten the stability of hydraulic structures in various forms. One way to indirectly
reduce scouring is to put collars and vanes. Collar is a thin plate at a certain height from the …

In this study, the performance and efficiency of cable in control of local scour around the pier
of the rectangular bridge have been investigated by changing the flow collision angle. In this …

An experimental study has been conducted on the effectiveness of two types of flow-altering
countermeasures placed around a cylindrical pier under clear water condition, which …

Introduction: Local scouring that occurs due to human construction of structures in the
course of rivers flow can lead to erosion of the river's bottom and threatens to change the …

The reviews of past researches have shown that abutment scour plays an important role in
bridge failures. Hence, protection of bridges against scour is a significant issue. For existing …
