The investigation was carried out in the Huancané basin. The objective of the present work is the determination of the efficient method to calculate the potential evapotranspiration for a Rain-Runoff Model in the Huancané Basin - Puno region. The data used were from seven meteorological stations from periods 1964 to 2016 registered by the SENAMHI institution. To determine the most efficient method, nine potential evapotranspiration methods were proposed (tank type "A", Penman Monteith, Thornthwaite and Wilm, Hargreaves based on Temperature and Radiation, Oudin, Blaney and Criddle, Turc and Jensen - Haise), with different input variables: average temperature, minimum temperature, maximum temperature, wind speed, relative humidity, evaporation and hours of sunshine, for which it was carried out hydrological modeling with the nine methods of ETP. With the hydrological model GR2M that has ...

La investigación se realizó en la cuenca Huancané. El objetivo del presente trabajo es la determinación del método más eficiente para calcular la evapotranspiración potencial para un Modelo Lluvia - Escorrentía en la Cuenca Huancané – región Puno. Los datos usados fueron son mensuales de siete estaciones meteorológicas de periodos 1964 a 2016 registrados por la institución SENAMHI, para determinar el método más eficiente se plantearon nueve métodos de evapotranspiración potencial (tanque tipo “A”, Penman Monteith, Thornthwaite y Wilm, Hargreaves en base a Temperatura y Radiación, Oudin, Blaney y Criddle, Turc y Jensen - Haise), con diferentes variables de entrada: temperatura media, temperatura mínima, temperatura máxima, velocidad del viento, humedad relativa, evaporación y horas de sol, Para Los cuales se realizó un modelamiento hidrológico con los nueve mé...
