Resumo: | The existence and preservation of urban parks or areas with vegetation remnants in may densely urbanized environments is an important alternative to maintain the hydrological functions of the soil next to its natural characteristics, mitigating the imbalances arising from urban densification in physical processes, especially hydrological. In this sense, the present study aimed to evaluate the hydrological efficiency of areas with remaining vegetation in the watershed of the Botafogo stream in Goiânia. The methodology comprised the evaluation of estimates of runoff velocity, effective precipitation, infiltration potential and runoff coefficient of areas that underwent urban densification and areas that remained preserved between the years 1988, 1998, 2008 and 2018. The results indicate an average increase of 3.8 m/s in runoff velocities, increased effective precipitation, reduced infiltration potential, as well as increased runoff coefficients, especially in densely urbanized areas. For the preserved areas the tendency was to maintain the values of hydrological variables in the evaluated period. It is noteworthy that the remaining vegetation areas tend to suffer the effects of surface runoff from densely urbanized areas located upstream, with the concentrated runoff causing erosive processes even in vegetated areas. Thus, the importance of maintenance as well as the installation of green areas in urban environments is highlighted as a way to mitigate imbalances, especially those related to hydrological functions of the soil. |

En este sentido, el presente trabajo tuvo como objetivo evaluar la eficiencia hidrológica de las áreas con vegetación remanente en la cuenca del arroyo Botafogo en Goiânia. La metodología comprendió la evaluación de las estimaciones de la velocidad de escorrentía, la precipitación efectiva, el potencial de infiltración y el coeficiente de escorrentía de las áreas que sufrieron densificación urbana y las áreas que permanecieron preservadas entre los años 1988, 1998, 2008 y 2018. Los resultados indican un aumento medio de 3,8 m/s en las velocidades de escorrentía, un aumento de la precipitación efectiva, una reducción del potencial de infiltración, así como un aumento de los coeficientes de escorrentía, especialmente en las zonas densamente urbanizadas. Para las zonas conservadas, la tendencia fue a mantener los valores de las variables hidrológicas en el periodo evaluado. Se destaca que las zonas de vegetación restantes tienden a sufrir los efectos de la escorrentía superficial procedente de las zonas densamente urbanizadas situadas aguas arriba, y la escorrentía concentrada provoca procesos erosivos incluso en las zonas con vegetación. De este modo, se destaca la importancia del mantenimiento así como de la instalación de zonas verdes en los entornos urbanos como forma de mitigar los desequilibrios, especialmente los relacionados con las funciones hidrológicas del suelo.A existência e preservação de parques urbanos ou áreas com remanescentes de vegetação em meio a ambientes densamente urbanizados se constitui em importante alternativa de manutenção das funções hidrológicas do solo próximas de suas características naturais, atenuando os desequilíbrios decorrentes do adensamento urbano nos processos físicos, em especial os hidrológicos. Neste sentido, com o presente trabalho objetivou-se avaliar a eficiência hidrológica de áreas com vegetação remanescente na bacia hidrográfica do córrego Botafogo em Goiânia. A metodologia compreendeu a avaliação das estimativas de velocidade de escoamento, precipitação efetiva, potencial de infiltração e coeficiente de escoamento superficial de áreas que passaram por adensamento urbano e de áreas que se mantiveram preservadas entre os anos de 1988, 1998, 2008 e 2018. Os resultados indicam aumento médio de 3,8 m/s nas velocidades de escoamento, aumento da precipitação efetiva, redução do potencial de infiltração, bem como aumento dos coeficientes de escoamento superficial, especialmente em áreas densamente urbanizadas. Para as áreas preservadas a tendência foi de manutenção dos valores das variáveis hidrológicas no período avaliado. Destaca-se que as áreas de vegetação remanescente tendem a sofrer os efeitos do escoamento superficial de áreas densamente urbanizadas localizadas à montante, com o escoamento concentrado provocando processos erosivos até mesmo em áreas vegetadas. Desta forma, destaca-se a importância da manutenção, bem como da instalação de áreas verdes em ambientes urbanos como forma de atenuar os desequilíbrios, especialmente aqueles relacionados às funções hidrológicas do solo.Research, Society and Development2021-12-02info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/1998010.33448/rsd-v10i15.19980Research, Society and Development; Vol. 10 No. 15; e15101519980Research, Society and Development; Vol. 10 Núm. 15; e15101519980Research, Society and Development; v. 10 n. 15; e151015199802525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/19980/20540Copyright (c) 2021 Wanessa Silva Rocha; Antônio Pasqualetto; Elizon Dias Nunes; Cibele de Moura Guimarãeshttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessRocha, Wanessa Silva Pasqualetto, AntônioNunes, Elizon Dias Guimarães, Cibele de Moura 2021-12-06T10:13:53Zoai:ojs.pkp.sfu.ca:article/19980Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:39:45.174663Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
