Abstract :

Bridges are the vital components of each country’s roads. Economic studies of the road construction show that the road bridges allocate much cost to it and due to the delicate structures of their system; they have great vulnerability as well. Therefore the detailed design of the various components of the bridge should be considered further. Erosion and transport of bed material is separated from it by a process called scouring. Occurrence of scouring around the bridge piers is one of the main reasons for the defeat and destruction of bridges and their instability. So it is important to provide methods to control and reduce this phenomenon. In the present study, the modeling of non-submerged plate’s perpendicular to the water flow has been expressed in upstream of the cylindrical pier using software SSIIM. Reducing the depth of the scouring hole was observed in these pages, and has a great influence around the bridge pier
