Resumo: The main objective of this work was to evaluate the evapotranspiration estimate by the SEBAL algorithm (surface energy balance algorithm for land) in the Brazilian semiarid region. For this, a bibliographic survey was made on the subject, to diagnose if there is convergence on the efficiency of the use of SEBAL in the application and planning of water resources, making a comparative analysis of several studies published in the scientific environment. The main results found converged that SEBAL is a good method, since the error oscillates smoothly compared to conventional estimates, in addition to allowing large geographic scale, high resolution and low cost analysis. It is considered that SEBAL, although it has limitations with atmospheric interference, can be used, what is recommended is to admit the margin of error and to carry out analyzes with historical series to statistically validate the results.

Para ello, se realizó una encuesta bibliográfica sobre el tema, para diagnosticar si existe convergencia sobre la eficiencia del uso de SEBAL en la aplicación y planificación de los recursos hídricos, realizando un análisis comparativo de varios estudios publicados en el entorno científico. Los principales resultados encontrados convergieron en que SEBAL es un buen método, ya que el error oscila suavemente en comparación con las estimaciones convencionales, además de permitir una gran escala geográfica, alta resolución y análisis de bajo costo. Se considera que SEBAL, aunque tiene limitaciones con la interferencia atmosférica, puede utilizarse, lo que se recomienda es admitir el margen de error y realizar análisis con series históricas para validar estadísticamente los resultados.O objetivo principal neste trabalho foi avaliar a estimativa da evapotranspiração pelo algoritmo SEBAL (surface energy balance algorithm for land) no semiárido brasileiro.
