Resumo: | The upper course of the Paraíba River drains one of Brazil's driest regions. Since April 2017, the Paraíba River has been receiving water from the transposition of the São Francisco River, altering the natural characteristics of the river regime. The aim of this study was therefore to analyze the fluvial regime of the upper Paraíba River before the arrival of the waters of the São Francisco River. To this end, historical rainfall and flow data were obtained from the ANA's HIDROWEB system (2018), and the volumes of the reservoirs were consulted through AESA (2019). Statistical treatments were applied in order to characterize the river regime and its relationship with rainfall distribution. The results showed that February, March and April are the months with the highest flows. On average there are 134 days with flow in the year and there is a downward trend in the number of days with flow. The river regime is 2 to 4 months, marked by short-lived floods. Weirs have a strong influence on the flow regime. The upper Paraíba River shows hydrological behavior typical of dryland rivers, marked by the spatio-temporal variability of river dynamics and the disconnection of hydrosedimentological flow throughout the basin. |

Desde abril de 2017 o Rio Paraíba começou a receber águas da transposição do Rio São Francisco, alterando as características naturais do regime fluvial. Assim, o presente estudo teve como objetivo analisar o regime fluvial do alto Rio Paraíba antes da chegada das águas do Rio São Francisco. Para tanto, foram obtidos dados históricos de precipitação e vazão junto ao sistema HIDROWEB da ANA (2018), e os volumes dos açudes foram consultados através da AESA (2019). Foram aplicados tratamentos estatísticos a fim de caracterizar o regime fluvial e sua relação com a distribuição das chuvas. Os resultados mostraram que fevereiro, março e abril são os meses de maior vazão. Em média ocorrem 134 dias com fluxo no ano e há uma tendência de diminuição do número de dias com fluxo. O regime fluvial é de 2 a 4 meses, marcado por cheias de curta duração. Os açudes exercem forte influência no regime de vazão. O alto Rio Paraíba apresenta comportamento hidrológico típico de rios de terras secas, marcado pela variabilidade espaço-temporal da dinâmica fluvial e desconexão do fluxo hidrossedimentológico ao longo da bacia.EDUFU - Editora da Universidade Federal de Uberlândia2024-02-20info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionAvaliado pelos paresapplication/pdfhttps://seer.ufu.br/index.php/caminhosdegeografia/article/view/6899810.14393/RCG259768998Caminhos de Geografia; Vol. 25 No. 97 (2024): Fevereiro; 183–200Caminhos de Geografia; Vol. 25 Núm. 97 (2024): Fevereiro; 183–200Caminhos de Geografia; v. 25 n. 97 (2024): Fevereiro; 183–2001678-6343reponame:Caminhos de Geografiainstname:Universidade Federal de Uberlândia (UFU)instacron:UFUporhttps://seer.ufu.br/index.php/caminhosdegeografia/article/view/68998/38113Copyright (c) 2024 Patricia da Conceição Dornellas, Richarde Marques da Silva, Rafael Albuquerque Xavier, Inocencio de Oliveira Borges Neto, Jonas Otaviano Praça de Souzahttp://creativecommons.org/licenses/by-nc-nd/4.0info:eu-repo/semantics/openAccessDornellas, Patricia da ConceiçãoSilva, Richarde Marques daXavier, Rafael AlbuquerqueBorges Neto, Inocencio de OliveiraSouza, Jonas Otaviano Praça de2024-02-20T12:57:54Zoai:ojs.www.seer.ufu.br:article/68998Revistahttps://seer.ufu.br/index.php/caminhosdegeografia/indexPUBhttp://www.seer.ufu.br/index.php/caminhosdegeografia/oaiflaviasantosgeo@gmail.com1678-63431678-6343opendoar:2024-02-20T12:57:54Caminhos de Geografia - Universidade Federal de Uberlândia (UFU)false |
