description Field studies and computer simulations of the macro-sewer system in Fortaleza-CE, Brazil, integrating the SWMM to QGIS, were carried out in order to investigate the hydrological-hydraulic behavior of the Interceptor Leste (IL), under various operational conditions. The results showed that only in an ideal operating scenario, without interference from silting or rainwater infiltration, the IL would be able to support its flows. In a scenario with the presence of silted stretches, IL would start to work under a forced pipe condition in most stretches, presenting critical points of overflow. The occurrence of speeds below 1.0 m/s was identified as a possible cause for silting. However, simulations indicated that the removal of sediment barriers would be sufficient to eliminate overflows. Assessing the interference of rainwater infiltration in the IL, it was observed that it would be able to withstand rain intensities below 10 mm/h, provided that no more than 5% of the sub-basin area contributed to the interceptor. These simulations resulted in rainfall contributions of up to 80 L/(s.km), which is substantially higher than the value of 6 L/(s.km) recommended by the Brazilian Association of Technical Standards (ABNT). The combined impact of sediment deposition with rainwater infiltration was also investigated, resulting in an increase in overflows compared to previous scenarios. Finally, simulations considering various possibilities for removing sediment barriers showed that this measure alone would not be sufficient to eliminate overflows in the region.

Os resultados mostraram que somente em um cenário de funcionamento ideal, sem interferência de assoreamento nem infiltração de águas pluviais, o IL seria capaz de suportar as suas vazões de alimentação. Já em um cenário com presença de trechos assoreados, o IL passaria a trabalhar sob condição de conduto forçado na maior parte dos trechos, apresentando pontos críticos de extravasamento. A ocorrência de velocidades inferiores a 1,0 m/s foi apontada como uma possível causa para o assoreamento. No entanto, simulações indicaram que a retirada de barreiras de sedimento seria suficiente para eliminar os extravasamentos. Avaliando-se a interferência de infiltrações de águas pluviais no IL, observou-se que o mesmo teria capacidade para suportar intensidades de chuva inferiores a 10 mm/h, desde que não mais que 5% da área das sub-bacias contribuísse para o interceptor. Essas simulações resultaram em contribuições pluviais parasitárias de até 80 L/(s.km), sendo este valor substancialmente superior ao valor de 6 L/(s.km) recomendado pela ABNT. Investigou-se ainda o impacto combinado da deposição de sedimento com a infiltração de águas pluviais, resultando em um aumento nos extravasamentos em relação aos cenários anteriores. Finalmente, simulações considerando várias possibilidades de retirada de barreiras de sedimento mostraram que essa medida por si só não seria suficiente para eliminar os extravasamentos na região.Revista DAEDrenagem urbanaEsgotamento sanitárioModelagem hidrológica-hidráulicaQGISSWMMModelagem do macrossistema de coleta de esgotos de Fortaleza-CEModeling the macro-sewerage system of Fortaleza-CEinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleinfo:eu-repo/semantics/openAccessporreponame:Repositório Institucional da Universidade Federal do Ceará (UFC)instname:Universidade Federal do Ceará (UFC)instacron:UFCPereira, Silvano PortoFernandes, Laryssa BarbosaSouza Filho, Francisco de Assis deLima Neto, Iran EduardoLICENSElicense.txtlicense.txttext/plain; charset=utf-82152http://repositorio.ufc.br/bitstream/riufc/69326/2/license.txtfb3ad2d23d9790966439580114baefafMD52ORIGINAL2021_art_ielneto.pdf2021_art_ielneto.pdfapplication/pdf4315416http://repositorio.ufc.br/bitstream/riufc/69326/1/2021_art_ielneto.pdf5716e4a84a2a42cb9b2aef745eef9d60MD51riufc/693262023-12-06 14:51:51.05oai:repositorio.ufc.br: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Repositório InstitucionalPUBhttp://www.repositorio.ufc.br/ri-oai/requestbu@ufc.br || repositorio@ufc.bropendoar:2023-12-06T17:51:51Repositório Institucional da Universidade Federal do Ceará (UFC) - Universidade Federal do Ceará (UFC)false
