Resumo: | The irregular rainfall and the years of low rainfall are important factors that lead farmers in the semi-arid region to seek alternatives that enable the continuity of production activities. The objective of the study was to analyse the behaviour of wells in the semi-arid region, in the Morada Nova Irrigation Project, located in the municipalities of Morada Nova and Limoeiro do Norte - CE. Monthly readings of static level of the wells during the years 2014 to 2019 were considered. The static level data were treated and organized in graphs and iso-depth maps to enable the observation of the water table behavior during dry and rainy seasons. The rise and depletion of each well over the year was analysed using the use and recovery coefficient. The graphs and maps showed a large drop in the static levels of the wells mainly in the year 2015 and recovery of the levels in the year 2018, the best year of rainfall; extending the recovery until 2019. The use and recovery coefficient made it possible to estimate how much was exploited of the wells during each year, highlighting the year 2015 with the highest depletion of the wells, with an average of 3.26 m, and the year 2016, with the coefficient value of 12.95. The year 2018 obtained the best coefficient, with the value of 0.58, and the average rise of the wells of 2.18 m. Such favorable indices are justified by the occurrence of rainfall above the historical average in the region, confirming strong collaboration and interference in the rainy and dry seasons. |

El objetivo del estudio fue analizar el comportamiento de los pozos en la región semiárida, en el Proyecto de Irrigación Morada Nova, localizado en los municipios de Morada Nova y Limoeiro do Norte - CE. Se consideraron las lecturas mensuales del nivel estático de los pozos durante los años 2014 a 2019. Los datos del nivel estático se trataron y organizaron en gráficos y mapas de isoprofundidad para permitir la observación del comportamiento del nivel freático durante los periodos secos y lluviosos. El aumento y el agotamiento de cada pozo a lo largo del año se analizaron mediante el coeficiente de utilización y recuperación. Los gráficos y mapas mostraron un gran descenso de los niveles estáticos de los pozos principalmente en el año 2015 y recuperación de los niveles en el año 2018, el mejor año de precipitaciones; prolongándose la recuperación hasta 2019. El coeficiente de utilización y recuperación permitió estimar cuánto se explotó de los pozos durante cada año, destacando el año 2015 con el mayor agotamiento de los pozos, con una media de 3,26 m, y el año 2016, con el valor del coeficiente de 12,95. El año 2018 obtuvo el mejor coeficiente, con el valor de 0,58, y la elevación media de los pozos de 2,18 m. Tales índices favorables se justifican por la ocurrencia de precipitaciones superiores a la media histórica en la región, lo que confirma una fuerte colaboración e interferencia en los períodos lluvioso y seco.As chuvas irregulares e os anos de baixas precipitações pluviométricas são fatores importantes que levam os agricultores do semiárido a buscarem alternativas que possibilitem a continuidade das atividades de produção. O objetivo do estudo foi analisar o comportamento de poços na região semiárida, no Projeto de Irrigação Morada Nova, situado nos municípios de Morada Nova e Limoeiro do Norte – CE. Foram consideradas leituras mensais de nível estático dos poços durante os anos de 2014 a 2019. Os dados de nível estático foram tratados e organizados em gráficos e mapas de isoprofundidade para possibilitar a observação do comportamento do lençol durante período seco e chuvoso. A ascensão e depleção de cada poço ao decorrer do ano foi analisada por meio do coeficiente de uso e recuperação. Os gráficos e os mapas mostraram grande queda nos níveis estáticos dos poços principalmente no ano de 2015 e recuperação dos níveis no ano de 2018, melhor ano de chuvas; estendendo a recuperação até 2019. O coeficiente de uso e recuperação possibilitou estimar o quanto foi explotado dos poços durante cada ano, destacando-se o ano de 2015 com a maior depleção dos poços, com média de 3,26 m, e o ano de 2016, com o valor de coeficiente de 12,95. O ano de 2018 obteve o melhor coeficiente, com o valor de 0,58, e a média de ascensão dos poços de 2,18 m. Tais índices favoráveis justificam-se pela ocorrência de chuvas acima da média histórica da região, confirmando forte colaboração e interferência nos períodos chuvosos e secos.Research, Society and Development2023-02-07info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/4016110.33448/rsd-v12i2.40161Research, Society and Development; Vol. 12 No. 2; e22212240161Research, Society and Development; Vol. 12 Núm. 2; e22212240161Research, Society and Development; v. 12 n. 2; e222122401612525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/40161/32897Copyright (c) 2023 José Wilson de Oliveira Magalhães; Raimundo Nonato Távora Costa; Kenya Gonçalves Nunes; Renata Nayara Câmara Miranda Silveira; José Alfredo de Albuquerquehttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessMagalhães, José Wilson de Oliveira Costa, Raimundo Nonato Távora Nunes, Kenya Gonçalves Silveira, Renata Nayara Câmara Miranda Albuquerque, José Alfredo de 2023-02-14T20:07:52Zoai:ojs.pkp.sfu.ca:article/40161Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2023-02-14T20:07:52Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
