Análisis de la relación entre precipitación y evapotranspiración en la hoya de Loja con fines de pronostico

Abstract

Abstract: The relationship between precipitation and evapotranspiration in the Loja Basin was analyzed during the years 2022 and 2023, using daily data from six climate stations. Evapotranspiration was calculated using the Penman-Monteith method, incorporating key climatic variables. The results indicated that precipitation, although considered in the initial calculation, did not have a significant impact on the final equations for estimating daily evapotranspiration. In contrast, variables such as temperature, solar radiation, and wind speed demonstrated greater influence, with the latter being the most determining factor at two of the stations analyzed. The equations obtained present a high level of certainty, with coefficients of determination between 93% and 98%. These findings contribute to the development of predictive models that can improve water resource management in the region.
