Summary: The rainfall-runoff models are recurrently used in the appropriation of project flow in basins that lack of streamflow data. The application of these models requires a number of decisions involving the selection of physiographic records databases in the area of ​​interest, the choice of equations for determining concentration times and appropriation methods of heavy rains equations that are used in forming of hietogramas, culminating in choosing the method that will be used in determining the hydrograph from which the peak flow rates will be raised. This study evaluated the influence that the combination of different physiographic records and hydrological processes modeling alternatives produces in determining design flows by applying the following methodological steps described above in the basin of River Arm North Left, using databases for free available, appropriating information using geographic information systems and HEC-HMS modeling program. The conduct of the study allowed us to obtain the maximum flow rates associated with return periods of 2 to 100 years, and from the analysis of this information, it was observed that considering the options selected for the composition of simulation scenarios, the choice of records and modeling alternatives leads to greater dispersion in the design flow. It also noted the relevance of the equation of the appropriation method of heavy rains in the variability of these flows.
