Hydrological relationships that occur in a watershed can be studied through models that simplify and represent the different phenomena that occur within it, being an important tool hydrological models, which are refined rapidly since the twentieth century can handle a large number data more easily and more representative calculations to reality. The purpose of this research is to develop and show the methodology and procedure, modeling rainfall - runoff to simulate flow in different points of interest using hydrological models SAC-SMA GR4J and Rs-Minerve software, applied to basins, bounded from Letrayoc gauging points and Conta, of Pisco and San Juan, respectively rivers; the advantage of the model is that they work on a daily basis, using as input precipitation and evapotranspiration (ETO). Letrayoc hydrometric stations and Conta of Pisco and San Juan, respectively, rivers had information of daily flows, which are used to calibrate and validate hydrological models GR4J and SAC-SMA; likewise, weather information was gathered in and around the watershed study, looking for stations that have information on a daily basis for the application of the models, sixteen stations with precipitation information and eight stations with temperature information is found, both to daily level within the basins: Pampas, Pisco and San Juan; simulation for a period of 23 years (1980 to 2002) was used. This research is based mainly on four aspects: a) analysis of information gathered (rainfall and hydrometric), where data quality was evaluated by statistical analysis; b) study delimitation of basins and sub basins, determining geomorphological and current parameters; c) simulation GR4J and SAC-SMA model, calibration and validation of the four parameters of the model parameters GR4J and sixteen SAC-SMA model; d) identification of the best performing modelin calibration and validation. For this research it shows that in the southern part of the Peruvian coast the GR4J model is not functional; however, the results obtained in the calibration step and validation for SAC-SMA model are satisfactory
