Resumo: | The percentage of precipitation that supplies the aquifers is essential for management of groundwater resources. This research presents an evaluation of the groundwater natural recharge in the small watershed of Uriboquinha creek, located in Marituba, Pará. The watershed has an area of 5 km² and, it made part of the Planning Unit Acará-Guamá. Estimates were made for a period from September 2018 to August 2019 based on two methods: Water Table Fluctuations (WTF) and Direct Potential Recharge (DPR). For the first, fourteen monitoring wells from the sanitary landfill located in Marituba-PA were used, while for the second, precipitation data from a rainfall station in Belém-PA and regionalized runoff data were used. The results obtained for the WTF method varied, well to well, between 1.2% to 26.5%, with an average value of 9.8%, equivalent to 378.9 mm, considering total precipitation of 3,866.8 mm during the study time, while for the DPR method, a rate of 6% was obtained, equivalent to 232 mm. The first method indicated an existing spatial variability in the study area, providing information on the hydraulic gradient and groundwater flow direction, indicated for studies with more precision in the recharge. While the second is more suitable for regulatory and water resource management purposes, providing a more conservative scenario. |

Esta investigación presenta una evaluación de la recarga natural del agua subterránea en la microcuenca del arroyo Uriboquinha, ubicado en Marituba, Pará. La microcuenca tiene una superficie de 5 km² y se inserta en la Unidad de Planificación Acará-Guamá. Las estimaciones fueron realizadas en un período comprendido entre septiembre de 2018 y agosto de 2019 en función de dos métodos: Fluctuaciones de la Superficie Libre (WTF) y Recarga Potencial Directa (DPR). Para el primero, se utilizaron catorce pozos de monitoreo del vertedero sanitario ubicado en Marituba-PA, mientras que, para el segundo, se usaron datos de precipitación de una estación de lluvia en Belém-PA y datos de escorrentía regionalizada. Los resultados obtenidos para el método WTF variaron, pozo a pozo, entre 1.2% a 26.5%, con un valor promedio de 9.8%, equivalente a 378.9 mm, considerando una precipitación total de 3,866.8 mm durante el tiempo de estudio, mientras que para el método DPR, se obtuvo una tasa del 6%, equivalente a 232 mm. El primer método indicó una variabilidad espacial existente en el área de estudio, proporcionando información sobre el gradiente hidráulico y la dirección del flujo de agua subterránea, indicado para estudios con más precisión en la recarga. Mientras que el segundo es más adecuado para fines regulatorios y de gestión de recursos hídricos, señalado para escenarios más conservadores.Para a gestão dos recursos hídricos subterrâneos é fundamental o conhecimento da porcentagem da precipitação que abastece os aquíferos. O presente trabalho apresenta uma avaliação da recarga natural do aquífero livre na microbacia hidrográfica do igarapé Uriboquinha, localizado no município de Marituba, Pará. A microbacia possui área de drenagem de 5 km² e está inserida na Unidade de Planejamento Acará-Guamá. As estimativas foram realizadas para um período de 12 meses, setembro de 2018 a agosto de 2019, com base em dois métodos: Variação de Nível de Água (VNA) e Recarga Potencial Direta (RPD). Para o primeiro, utilizou-se quatorze poços de monitoramento do aterro sanitário localizado em Marituba-PA, enquanto que para o segundo, utilizou-se dados de precipitação de uma estação pluviométrica em Belém-PA e dados de escoamento superficial regionalizado. Os resultados obtidos para o método VNA variaram, poço a poço, entre 1,2% a 26,5%, com valor médio de 9,8%, equivalente a 378,9 mm, considerando uma precipitação total de 3.866,8 mm durante os 12 meses considerados, enquanto que para o método RPD, obteve-se uma taxa de 6%, equivalente a 232 mm. O primeiro método indicou uma variabilidade espacial existente na área de estudo, fornecendo informações sobre gradiente hidráulico e sentido de escoamento subterrâneo, indicado para estudos mais exigentes quanto a precisão dos valores de recarga. Enquanto que o segundo é mais indicado para fins regulatórios e de gestão dos recursos hídricos, por fornecer cenário mais conservador.Research, Society and Development2020-08-20info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/744110.33448/rsd-v9i9.7441Research, Society and Development; Vol. 9 No. 9; e307997441Research, Society and Development; Vol. 9 Núm. 9; e307997441Research, Society and Development; v. 9 n. 9; e3079974412525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/7441/6461Copyright (c) 2020 Giovanni Chaves Penner; Rubens Takeji Aoki Araújo Martins; Moisés Marçal Gonçalveshttp://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessPenner, Giovanni ChavesMartins, Rubens Takeji Aoki Araújo Gonçalves, Moisés Marçal 2020-09-18T01:42:11Zoai:ojs.pkp.sfu.ca:article/7441Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:30:09.811073Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
