Resumen

The present investigation has been carried out in the hydrographic basin of the Huaura river, which aims to generate daily flows. Variables such as basin area, mean rainfall, effective rainfall, evapotranspiration and daily averages of flow rates have been used. The methodology used was the application of the GR4j method. This model is considered parsimonious because it has only 4 parameters. The validity and susceptibility of the variables studied has been corroborated. Furthermore, the influence of the factors in the variation of the result must be evaluated. It was determined that the results are acceptable for obtaining daily flows in the Huaura river basin.
