The Effect of Submerged Plates on the Square Bridge Pier scours Using Software SSIIM

Bridges are among the most important and most prolific river structures ever used. The three commonly used methods to deal with the scouring phenomenon around the bridges are to place the piers in a lower level than the depth of the erosive pit, to reduce the power of the vortex produced around the base, to use the shrub protection cover, or to use a collar, gaps, or submerged plates around the base bridges. Submerged plates are structures that are installed at the bottom of the river with an angle to the main stream and to prevent river erosion, rivets and base structures of the water and waterway reformation and morphology of the bed, which produces a secondary vortex and Changing the flow pattern in the river bed and, consequently, changing sediment transport and erosion. In this research, the effect of square cross-sectional diameter and the effect of submerged panels on scouring are investigated using SSIIM software.
