The main objective of this research is to determine the influence of the Chuquillanqui bridge and the Chuquillanqui river access embankment in the Chuquillanqui bridge section, we generated different scenarios, for different periods of return in non-permanent flows, the models that were generated with the bridge recreates the situation as it is currently, the model without bridge, simulates the behavior when we remove the bridge and access embankment, and the proposed model, is our proposed solution that consists of removing bridge, access embankment and part of the topography. In addition, we propose the construction of a long bridge with a light of 298.00 m, supported by 5 pillars and 2 abutments, the shape of the pillars has been considered ellipsoid, because according to literature and research, those are that have a better hydrodynamic behavior. Engineering studies were carried out, such as the topographic survey where it was found that the section upstream of the bridge and access embankment between the 0 + 000 - 0 + 805 progressives has a slope of 2.035%, and the slope in the waters section below the bridge and access embankment between the progressive 0 + 805 - 1 + 500 is 0.830%. The background material is a coarse gravel, has characteristic diameter D 50 of 27.21 mm and its specific gravity is 2.59. The generated scenarios have been considered as periods of return 5, 10, 25, 50 and 100 years, taking 5 instants per hydrogram to analyze. Meyer Peter Müller and Shields methods have been used for the calculations of the background and critical stress, where the critical tension, the force necessary for the initiation of the movement is 20.01 N / m2, and the necessary tension for start the movement in the first section is 0.12 m, and in the second section is 0.30 m. In conclusion, it was obtained that the bridge and access embankment do have a significant influence on the sedimentation of the Chuquillanqui River, since these elements have been modifying the slope considerably upstream as downstream, with the proposal it is estimated that the river will recover its natural slope with the passing of time.
