With the advancement of technology for design and construction of structures, it has witnessed the construction of bridges with modern forms, including bridges at different angles. Bridges are one of the most important river structures. One of the major causes of bridge collapse is scouring around the bridges. The scouring of various forms of sustainability of hydraulic structures is threatened and erosion. All year round many bridges around the world are damaged due to the role of hydraulic elements. In this research, numerical simulation of scouring in groups 3 and 4 of the bridge at 0, 10, and 15 degrees, and using the flow rate and constant diameter of the foundations using the Flow3D software are considered and the regression analysis is evaluated. . The simulation results indicate that with increasing the slope of the foundations, from 0 to 15 degrees, the scouring rate is reduced, and scouring is high above the base of the base. Also, maximum scouring has been reported around the bases. This research confirms that the slope of the cylindrical bridges of the bridge relative to the straight line directly affects the scouring around the bridges.
