After the disaster that produced the phenomenon Coastal Child of the summer of 2017, the Regional Government and the National Water Authority (ANA) signed an agreement of institutional cooperation to develop the project "Deviation of the waters of the Quebrada San Idelfonso to the River Moche for flood protection purposes of the City of Trujillo and the District of El Porvenir. In this juncture, the authors, we study the consequences that will lead to the diversion of the waters of the San Idelfonso creek in the foundations of the Moche bridge. The present research contains background studies on scour at bridges in the world and in Peru, as well as the theoretical foundations on which the various formulas for the calculation of scouring are based. For the study of the basin the method of direct measurements has been used, as well as measurements with technological tools for areas too extensive. The methodology used in the calculation of general scour was by the method of Lischtvan-Levediev, for the scour in stirrups was by the method of K. F. Artamonov and for the scour in pillars Neill's method was used, together with the HEC RAS program. For the flows of the Moche river, statistical methods were used with data provided by the different entities in charge of meteorological and hydraulic measurements. The results obtained from the calculation of the San Idelfonso micro-watershed and the Moche river records show us that the incidence of the waters of the San Idelfonso stream represents only 5% of the river's flow, which is why we conclude that the expected scour in the pillars and abutments of the Moche bridge it does not represent a danger for its stability. Consequently, the proposal of the ANA is technically viable. However, we were able to determine an error in the assessment of the competent authorities regarding the flow that can be generated by the San Idelfonso micro-watershed; and it is that it has not been considered that the flow that occurred on March 19, 2017, corresponds to a flow of dam breakage, whose overflow left enormous damage in the city of Trujillo. Finally, we propose some recommendations resulting from the recognition of the land made after the two expeditions to the San Idelfonso basin, as well as the existing literature on watershed management.
