Resumo: | This study aimed at analyzing the effects of climate seasonality and of urbanization in the determination of the Acaraú river Water Quality Index - WQI, located in the intraurban stretch of the city of Sobral (Ceará/Brazil). The area studied extends for 15 km encompassing a river system with entrance zones (non-urbanized), mixture zones (highly urbanized) and exit zones (moderately urbanized). WQI allows assessing the quality of raw water. To calculate it, nine parameters of water quality were assessed. Analytical procedures with water samples in five collection points were adopted. The study took place between March/15 and March/16 comprehending the dry season, rainy pre-season and the wintry quarter. Results indicated that hydroclimate factors and the forms of land use and occupation directly influenced the WQI values - in which values of “bad” quality are mainly observed in the dry season in the intraurban areas of Sobral. This may indicate that non-treated charges of domestic effluent get to the main canal of Acaraú river. Therefore, it is concluded that climate seasonality associated with forms of land use and occupation plays an important role in the water quality of Acaraú river in Sobral. |

O trecho estudado possui uma extensão de 15 km que abrange um sistema fluvial com zonas de entrada (sem urbanização), mistura (altamente urbanizada) e saída (mediamente urbanizada). O IQA permite avaliar a qualidade da água bruta. Para o cálculo do IQA foram avaliados nove parâmetros de qualidade de água. Para isso, foram adotados procedimentos analíticos com amostragem de água em cinco pontos de coleta. O estudo ocorreu de março/15 a março/16, compreendendo os períodos de estiagem, pré-estação chuvosa e quadra invernosa. Os resultados indicaram que fatores hidroclimáticos e a própria forma de uso e ocupação, influenciaram diretamente nos valores de IQA, sendo que os valores de qualidade “ruim” são observados, principalmente, no período de estiagem, no espaço intraurbano de Sobral. Isso pode indicar que cargas de efluentes domésticos chegam sem tratamento ao canal principal do rio Acaraú. Conclui-se, portanto, que a sazonalidade climática associada às formas de uso e ocupação desempenha um papel importante na qualidade das águas do rio Acaraú em Sobral.EDUFU - Editora da Universidade Federal de Uberlândia2019-07-11info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionAvaliado pelos paresapplication/pdfhttps://seer.ufu.br/index.php/caminhosdegeografia/article/view/4147910.14393/RCG206941479Caminhos de Geografia; Vol. 20 No. 69 (2019): Março; 421-436Caminhos de Geografia; Vol. 20 Núm. 69 (2019): Março; 421-436Caminhos de Geografia; v. 20 n. 69 (2019): Março; 421-4361678-6343reponame:Caminhos de Geografiainstname:Universidade Federal de Uberlândia (UFU)instacron:UFUporhttps://seer.ufu.br/index.php/caminhosdegeografia/article/view/41479/26411Copyright (c) 2019 Francisco Bruno Monte Gomes, Davis Pereira de Paulainfo:eu-repo/semantics/openAccessGomes, Francisco Bruno Montede Paula, Davis Pereira2019-07-23T17:23:15Zoai:ojs.www.seer.ufu.br:article/41479Revistahttps://seer.ufu.br/index.php/caminhosdegeografia/indexPUBhttp://www.seer.ufu.br/index.php/caminhosdegeografia/oaiflaviasantosgeo@gmail.com1678-63431678-6343opendoar:2019-07-23T17:23:15Caminhos de Geografia - Universidade Federal de Uberlândia (UFU)false |
