Influence of different skew angles of the submerged vane on pressure flushing performance [PDF]
Scientific Reports, 2023 Siltation significantly threatens a reservoir’s original storage capacity and lifespan. Pressure flushing is an effective measure against siltation through the partial drawdown of the reservoir water level with limited flushed cone volumes in front of ...

Combination of Riprap and Submerged Vane as an Abutment Scour Countermeasure
Fluids, 2023 Scour is one of the main causes of hydraulic structural failures. The present experimental study examines the use of riprap, submerged vanes, and a combination of these for scour reduction around vertical walls and spill-through abutments under clear ...

The Effects of submerged vanes inclination angle on sediment transport into sub-channel
Wasit Journal of Engineering Sciences, 2023 The sub-channels that branch from the larger rivers may be manmade or natural. From the major channels, these sub-channels transfer sediments and water. The deposition of sediments at the entrance, sub-channel is a significant research challenge because

Study of Streamlines under the Influence of Displacement of Submerged Vanes in Channel Width, and at the Upstream Area of a Cylindrical Bridge Pier in a 180 Degree Sharp Bend [PDF]
Journal of Hydraulic Structures, 2018 In this paper, submerged vanes were placed at the upstream area of a bridge pier located at the 90 degree angle. Then, using the laboratory equipment, a study of flow pattern was conducted throughout the bend, specifically around the pier and submerged ...

Experimental Analysis of the Effect of Geometric Shape of Submerged Vanes on Sedimentation Flows at Lateral Intake Entrance in River Bends [PDF]
علوم و مهندسی آبیاری, 2019 The separation zone in the entrance of intake channel has no effect on flow discharge but it reduces the effective cross-sectional area of the intake, as well as the bed load, which enters the intake due to low velocity flow deposits in this area ...

Experimental Investigation of Flat, Curved and Angled Submerged Vane’s Placement Effect on Bridge Pier Scouring [PDF]
علوم و مهندسی آبیاری, 1970 One of the methods for a local scour countermeasure at bridge piers is the use of submerged vanes. Vanes change the regime of bed load movement that led to control place of deposition and erosion.

Experimental Investigation of Submerged Vanes’ Shape effect on river-bend stability [PDF]
Journal of Hydraulic Structures, 2013 In river meandering, when flow passes through a bend, reduction of flow velocity and rising hydrostatic pressure cause super elevation phenomena at outer side and reduction of water surface at inner-side of the bend.

Numerical Simulation of Flow Pattern around the Bridge Pier with Submerged Vanes [PDF]
Journal of Hydraulic Structures, 2016 Bridges are very important for establishing communication paths. For this reason, it is important to control scour around bridge piers. Several methods have been proposed for scour control. One of the most useful methods is the use of submerged vanes. In
