In the present work of professional sufficiency, the “Design study and hydraulic modeling for transversal walls” will be presented. This is contemplated in the project for the progressive recovery of the underground reserve carried out in the Rímac river. This project aimed to reduce the gap that exists on the service of drinking water provided by the PTAP of Huachipa, since currently only 1,32 m3.s-1 is being produced and not the designed flow of 5 m3.s-1. This gap will be mitigated by artificially induced recharge, where the volume of surface water is used in flood periods with the effect of installing transversal walls and tube wells. The design and hydraulic modeling of the cross walls was carried out in the 25+000 to 40+700 km stretch of the Rímac river bed. The hydraulic model was carried out with the HEC-RAS 1D software in permanent flow, for two scenarios: one in the current situation and another for the model with transversal walls. For the design of the transversal walls, a return period of 100 and 500 years was considered. Once the dimensions and locations of these walls were defined, they were entered into the hydraulic model. Then, the effect generated by their transversal placement in the channel was evaluated for a period of flood and low water to analyze if the variation of the wetted area, depth of water, speed and number of Froude would represent a benefit for the infiltration increase in the section of study. Finally, it was confirmed that there is a 32 percent increase in the wetted area with the implementation of the transverse walls, generating a greater contact area between the water flow and the soil, that is, increasing the main variable for infiltration. Obtaining an increase of 26 percent and 32 percent in infiltration flows during the flood and dry season, respectively.
