Resumo: The knowledge of morphometry, relief and drainage network of hydrographic basins is important for environmental management. Therefore, this study aims to characterize the morphometry and identify the relief characteristics in nine hydrographic basins tributary of the Iguaçu River. The characterization of slopes, drainage network and slope was performed using a Digital Terrain Model (DTM) and the data obtained were visually compared to the results of the topographic maps of the National Water Agency (ANA) (2015). The analyzed basins presented in general elongated shapes, being little susceptible to floods, with undulating relief, with intermediate to poor drainage and sinuosity from intermediate to high. The results obtained are similar to those obtained by ANA (2015), based on smaller scales. The hierarchies for each basin were satisfactory, as well as the methodology used, as it does not require the use of sophisticated machines for its execution, and results in reliable data with little loss of precision. The results are unprecedented for these basins and the estimated geomorphological variables can support decision making both in relation to the risks of anthropic activities and the definition of conservation areas, especially areas of interest for the conservation of water and aquatic ecosystems.

Por tanto, este estudio tiene como objetivo caracterizar la morfometría e identificar las características del relieve en nueve cuencas tributarias del río Iguazú. La caracterización de taludes, red de drenaje y talud se realizó mediante un Modelo Digital de Terreno (DTM) y los datos obtenidos se compararon visualmente con los resultados de los mapas topográficos de la Agencia Nacional del Agua (ANA) (2015). Las cuencas analizadas se presentaron en formas generalmente alargadas, siendo poco susceptibles a inundaciones, con relieve ondulado, con drenaje intermedio a pobre y sinuosidad de intermedio a alto. Los resultados obtenidos son similares a los obtenidos por ANA (2015), basados en escalas menores. Las jerarquías para cada cuenca fueron satisfactorias, así como la metodología utilizada, ya que no requiere el uso de máquinas sofisticadas para su ejecución, y da como resultado datos confiables con poca pérdida de precisión. Los resultados son inéditos para estas cuencas y las variables geomorfológicas estimadas pueden apoyar la toma de decisiones tanto en relación a los riesgos de las actividades antrópicas como en la definición de áreas de conservación, especialmente áreas de interés para la conservación de agua y ecosistemas acuáticos.O conhecimento da morfometria, do relevo e rede de drenagem bacias hidrográficas é importante para a gestão ambiental. Portanto, este estudo visa caracterizar a morfometria e identificar as características do relevo em nove bacias hidrográficas afluentes do rio Iguaçu. A caracterização de vertentes, rede de drenagem e declividade foi realizada utilizando um Modelo Digital de Terreno (MDT) e os dados obtidos foram comparados visualmente aos resultados das cartas topográficas da Agência Nacional de Águas (ANA) (2015). As bacias analisadas apresentaram de maneira geral formas alongadas, sendo pouco suscetíveis à enchentes, com relevo ondulado, possuem drenagem intermediária a pobre e sinuosidade de intermediária a alta. Os resultados obtidos se assemelham aos obtidos pela ANA (2015), baseados em escalas menores. As hierarquias para cada bacia foram satisfatórias, assim como a metodologia utilizada, pois não requer a utilização de máquinas sofisticadas para a sua execução, e resulta em dados confiáveis com pouca perda de precisão. Os resultados são inéditos para essas bacias e as variáveis geomorfológicas estimadas podem apoiar a tomada de decisão tanto em relação aos riscos das atividades antrópicas quanto para a definição de áreas de conservação, especialmente de áreas de interesse para a conservação da água e dos ecossistemas aquáticos.Research, Society and Development2022-01-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/2569810.33448/rsd-v11i2.25698Research, Society and Development; Vol. 11 No. 2; e42811225698Research, Society and Development; Vol. 11 Núm. 2; e42811225698Research, Society and Development; v. 11 n. 2; e428112256982525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/25698/22717Copyright (c) 2022 Jhony Ferry Mendonça da Silva; Elaine Fernandes Celestino; Guilherme Henrique Barros de Souza; Max Portuguez Obeso; Maristela Cavicchioli Makrakis; Sérgio Makrakishttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessSilva, Jhony Ferry Mendonça daCelestino, Elaine Fernandes Souza, Guilherme Henrique Barros deObeso, Max PortuguezMakrakis, Maristela Cavicchioli Makrakis, Sérgio2022-02-07T01:42:50Zoai:ojs.pkp.sfu.ca:article/25698Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:43:55.368153Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false
