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.

Empirical Formulas to Predict the Maximum Scour Depth With Debris Accumulation Around A Single Cylindrical Bridge Pier: An Experimental Study [PDF]
Engineering and Technology Journal, 2020 The probability of debris accumulation near bridge piers during the heavy storm and river flood convert the hydraulic action of flow and increase the scour depth due to the reduction of flow area and the increase in velocity of flow.

Experimental investigation of the angle effect of the cylindrical bridge group piers relative to the flow direction on the maximum scour depth of the piers [PDF]
علوم و مهندسی آبیاری, 2022 Bridges are one of the important structures in the field of land communication. With the construction of these structures in the river, a flow pattern with a three-dimensional structure is formed in the vicinity of its piers, and as a result of ...
