Estimativa da evapotranspiração em uma área de plantio de mangueira no Nordeste do Pará: uma abordagem integrada com os Métodos de Bowen e modelo METRIC-EEFLUX
(Universidade Federal do Pará, 2024-03-22) MOREIRA, Antônio Carlos Novaes; SOUSA, Adriano Marlisom Leão de; http://lattes.cnpq.br/4371199443425884; https://orcid.org/0000-0002-2809-5318
The research presents a comparative evaluation of the water consumption of mango in the Northeast region of Pará, highlighting the importance of evapotranspiration estimation for the study of the hydrological cycle and sustainability of agricultural. The use of traditional methods, such as the Bowen Ratio Method, and remote sensing techniques, specifically the METRICEEFLUX model, are explored to estimate the crop’s Evapotranspiration. This revealed an influence of the Tommy Atkins mango orchard on the water dynamics in Cuiarana, Pará. The ETr varied notably between the crops, with an average daily consumption of 4.59 mm and 4.84 mm, respectively, for Crops 1 and 2. The study offers an in-depth understanding of the local hydrological cycle, with the orchard contributing about 185,958 m³ to the cycle. The analysis of ETr through METRIC-EEFLUX revealed notable spatial and temporal variability, with some discrepancies in relation to the Bowen method. Despite a strong positive correlation, METRICEEFLUX tended to overestimate ETr. The performance of the METRIC-EEFLUX model was classified as “poor”, highlighting the need for continuous improvement and specific calibration for the Amazon region. The study emphasizes the need for continuous research to improve the accuracy of water estimates, providing valuable insights for the effective management of water resources.
