This research work presents the obtaining and comparison of the depth of the society that is generated in the Victoria Bridge according to the following variables: topography, granulometry and 03 types of flows with different return periods, 50, 100 and 500 years. With these data, the models were published: one-dimensional in the Hec Ras software and twodimensional in the IBER software. The depth of the local scour and the general scour was obtained to be added up and obtain the total scour. The investigation showed that the decolonization upstream of the river, plus the construction of a dike causes a new water current that will affect mainly the pillars of the left margin. Having 02 types of pillar, sharp tip pile and group of cylinders. These reach a depth of total scour in the onedimensional kmodel of 3.79 m for a flow of 1052.42 m3 / s with a return period of 50 years; 4.07 m for a flow of 1359.06 m3 / s with a return period of 100 years; 5.48 m for a flow of 2295 m3 / s with a return period of 500 years. Meanwhile, for the two-dimensional model it will reach a total depth of 5.62 m for a flow of 1052.42 m3 / s with a return period of 50 years; 6.40 m for a flow of 1359.06 m3 / s with a return period of 100 years; 6.72 m for a flow of 2295 m3 / s with a return period of 500 years. It was observed that the two-dimensional model showed higher depths of scour with respect to the one-dimensional model, this is because of the IBER software analyzes the behavior of water in 2 directions, thus being a more optimal analysis.
