Resumo: | Rainwater interception losses are often neglected due to measurement difficulties and great spatial and temporal variability. Losses can be significant and therefore have a severe impact on the water balance of a watershed. The present work had as objective to obtain the pluvial interception in the hydrographic basin of the Alto Juruá (BHAJ), through the Gash model, based on remote sensing data. The platform for data processing was the Google Earth Engine, which allowed the assessment and comparison of rainfall variables, normalized difference vegetation index and leaf area index (LAI), on a monthly and annual scale, in the period of 2003 to 2016. Thus, it was possible to observe that the interception has a strong relationship with LAI and vegetation cover, recording an annual average of 11.2% of rain intercept by the forest within the BHAJ, with its highest percentages in the rainiest periods. |

Las pérdidas pueden ser significativas y, por lo tanto, tener un impacto severo en el balance hídrico de una cuenca. El presente trabajo tuvo como objetivo obtener la interceptación pluvial en la cuenca hidrográfica del Alto Juruá (BHAJ), a través del modelo Gash, con base en datos de teledetección. La plataforma para el procesamiento de datos fue Google Earth Engine, que permitió la evaluación y comparación de las variables de precipitación, índice de vegetación de diferencia normalizada e índice de área foliar (LAI), en una escala mensual y anual, en el período de 2003 a 2016. Así, se pudo observar que la interceptación tiene una fuerte relación con la LAI y la cobertura vegetal, registrando un promedio anual de 11,2% de interceptación de lluvia por el bosque dentro del BHAJ, con sus mayores porcentajes en los períodos más lluviosos.As perdas por interceptação das águas pluviais são frequentemente negligenciadas devido às dificuldades de medição e grande variabilidade espacial e temporal. As perdas podem ser significativas e, portanto, ter um impacto severo no balanço hídrico de uma bacia hidrográfica. O presente trabalho teve como objetivo obter a interceptação pluvial na bacia hidrográfica do Alto Juruá (BHAJ), por meio do modelo de Gash, com base em dados de sensoriamento remoto. A plataforma para o processamento dos dados foi o Google Earth Engine, no qual permitiu avaliar e comparar as variáveis de precipitação pluvial, índice de vegetação com diferença normalizada e índice de área foliar (IAF), em escala mensal e anual, no período de 2003 a 2016. Dessa forma, foi possível observar que a interceptação possui uma forte relação com IAF e a cobertura vegetal, registrando uma média anual de 11,2% de interceptação de chuva pela floresta dentro da BHAJ, apresentando suas maiores porcentagens nos períodos mais chuvosos.Research, Society and Development2022-01-02info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/2434310.33448/rsd-v11i1.24343Research, Society and Development; Vol. 11 No. 1; e6711124343Research, Society and Development; Vol. 11 Núm. 1; e6711124343Research, Society and Development; v. 11 n. 1; e67111243432525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/24343/21635Copyright (c) 2022 Cassia Fernanda de Souza Farias; Jefferson Vieira José; Kelly Nascimento Leite; Moisés Damasceno Souza; Marcos Antonio Correa Matos Amaral; Sonaira Souza da Silva https://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessFarias, Cassia Fernanda de Souza José, Jefferson Vieira Leite, Kelly Nascimento Souza, Moisés Damasceno Amaral, Marcos Antonio Correa Matos Silva , Sonaira Souza da 2022-01-16T18:08:18Zoai:ojs.pkp.sfu.ca:article/24343Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:42:55.966050Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
