Resumo: | Anthropogenic interventions aimed at changes, permanent or temporary, in the hydrological regime of channels alter not only fluvial processes but can also generate changes in the morphologies of channels. Thus, understanding the possibilities of adjusting the river morphology is essential for analyzing the impact of these adaptations, allowing us to identify which controlled areas were modified. In this perspective, the objective article evaluates the adjustment capacity of the different river styles of the upper course in the Paraíba semi-arid region of Paraíba. The methodology of fluvial styles was used, through which it was possible to characterize the different stretches of the channel and the adjustment capacity of each stretch based on the morphology/texture of the channel and associated morphological units. The analysis identified four river styles, reflecting the low environmental variability and highlighting the predominance of unconfined stretches with sandy bars, which have a high adjustment capacity. Thus, it is possible to understand that predominantly the area has a high capacity for lateral and vertical adjustments, with the possibility of removing/modifying the sandy bars. Among the possible modifications, the stabilization of sandy bars by vegetation stands out, allowing the formation of islands and the lateral expansion of channels, recurrent behaviour for this type of hydrological alteration. |

Desse modo, o entendimento das possiblidades de ajustes da morfologia fluvial é primordial para a análise do impacto dessas modificações, possibilitando identificar quais áreas sofreram modificações. Nesta perspectiva o artigo objetiva avaliar a capacidade de ajuste dos diferentes estilos fluviais do alto curso do rio Paraíba, no semiárido paraibano. Foi utilizada a metodologia dos estilos fluviais, pela qual foi possível caracterizar os diferentes trechos do canal e a capacidade de ajuste de cada trecho, tendo como base a morfologia/textura do canal e unidades morfológicas associadas. A partir da análise foram identificados quatro estilos fluviais, o que reflete a baixa variabilidade ambiental, destacando-se a predominância de trechos não confinados com presença de barras arenosas, os quais apresentam alta capacidade de ajuste. Dessa forma, é possível entender que predominantemente a área apresenta alta capacidade para ajustes laterais e verticais, com a possibilidade de remoção/modificação das barras arenosas. Entre as modificações possíveis destaca-se a estabilização das barras arenosas pela vegetação, possibilitando a formação de ilhas, e a expansão lateral dos canais; comportamento recorrentes para esse tipo de modificação hidrológica.EDUFU - Editora da Universidade Federal de Uberlândia2023-12-05info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionAvaliado pelos paresapplication/pdfhttps://seer.ufu.br/index.php/caminhosdegeografia/article/view/6847410.14393/RCG249668474Caminhos de Geografia; Vol. 24 No. 96 (2023): Dezembro; 88–100Caminhos de Geografia; Vol. 24 Núm. 96 (2023): Dezembro; 88–100Caminhos de Geografia; v. 24 n. 96 (2023): Dezembro; 88–1001678-6343reponame:Caminhos de Geografiainstname:Universidade Federal de Uberlândia (UFU)instacron:UFUporhttps://seer.ufu.br/index.php/caminhosdegeografia/article/view/68474/37244Copyright (c) 2023 Jonas Otaviano Praça de Souza, Alisson Santos, Helder Cavalcante de Oliveirahttp://creativecommons.org/licenses/by-nc-nd/4.0info:eu-repo/semantics/openAccessSouza, Jonas Otaviano Praça deSantos, AlissonOliveira, Helder Cavalcante de2023-12-05T15:11:44Zoai:ojs.www.seer.ufu.br:article/68474Revistahttps://seer.ufu.br/index.php/caminhosdegeografia/indexPUBhttp://www.seer.ufu.br/index.php/caminhosdegeografia/oaiflaviasantosgeo@gmail.com1678-63431678-6343opendoar:2023-12-05T15:11:44Caminhos de Geografia - Universidade Federal de Uberlândia (UFU)false |
