Abstract :
Construction on rivers is inevitable to communicate and reduce costs quickly or to control and control the floods. But the construction of hydraulic structures that are directly exposed to flood currents is not possible only by relying on the assessment of the capacity of structures and their analysis solely on the basis of the principles governing the solid mechanics and should be in addition to the structural examination, the impact of issues. The environment is also examined on structural stability. Estimation of maximum flow around the bridge base with semi-experimental relationships is not a reliable method. One of the methods for recognizing the erosion process is the flow of the flow structure. In this research, the three-dimensional simulation of the steep base is discussed. For this purpose, using the compass software that has a three-dimensional flow model was used to simulate the turbulent flow pattern around the bridge base. To verify the software, the study pattern was performed around the steep base. The simulation results have a good match with real results, which represents the high capability of the simulation model in predicting the steep base.
