Abstract: This study carried out the winter and summer design flood routing of the Luis Donaldo Colosio Dam (Huites), Mexico, to obtain the discharge hydrographs by the spillway and the maximum elevations reached in the reservoir; for this purpose, the Modified Puls Method was applied using Hec hms free software to take advantage of the non-licensed and its wide use in hydrology and water management problems; additionally comparisons were made with the numerical method of the Federal Commission and Electricity (CFE) which is the unit in charge; the two methods are based on the continuity equation and the reservoir curves elevations capacities data but have some variants in the form of the algorithms. Different initial storage conditions were considered taking into account different Normal Water Level (NWL) in the time of winter and summer as well as different discharge rules. The Huites dam on the Fuerte River in Mexico, has special characteristics both for the importance of the winter floods that are typically presented in the northwest of the country, and for the main purpose of said dam that is hydropower generation, in addition its outflows represent contributions to another dam called Hidalgo Miguel whose main use is irrigation. The results of the performed flood routing for return periods of 100 , 1000 and 10000 years , using the Modified Puls Method with Hec hms reported more conservative maximum discharge than those reported by the CFE numerical method . The worst scenarios were also identified in the winter floods (from analyzing the average daily inflows to the reservoir during the months of October to March) than the summer floods (from April to September).
