Resumo: This work presented the development and testing of a large-scale rainfall simulator (LSRS) to be used as a research tool on rainfall-runoff and associated transport processes in urban areas. The rainfall simulator consists of a pressurized water supply system which supplies a set of 16 full-cone nozzles. Artificial rainfall with different rainfall intensities can be produced over an area of 100 m2 in a V shape. The assembly is housed in a tailor-made acrylic structure to eliminate the influence of wind and natural rainfall. Runoff is measured and collected at the outlet of the drainage basin, from where it is pumped to a storage tank that enables the reuse of water. Runoff hydrographs and pollutographs are presented as examples of possible outcomes from this facility. The LSRS is showed to be able to reproduce the rainfall-runoff and pollutant transport processes under simulated rainfall events with intensity and spatial uniformity similar to other experiments described in the literature.

O simulador é composto por um sistema pressurizado de abastecimento de água que abastece um conjunto de 16 bicos aspersores. Chuvas artificiais com diferentes intensidades de precipitação podem ser produzida sobre uma bacia de drenagem com área de 100.0 m2 em forma de V. O simulador é protegido por uma estrutura em acrílico que elimina a influência do vento e da chuva natural. A vazão é medida e coletada no exutório da bacia de drenagem, de onde é bombeada para um reservatório de armazenamento que permite a reutilização da água. Hidrogramas de vazão e polutogramas são apresentados como exemplos de possíveis resultados de ensaios a serem realizados com este equipamento. O LSRS demonstrou ser possível reproduzir o processo de chuva-vazão e processos associados sob eventos de chuva simulada com intensidade e distribuição espacial semelhantes a outros experimentos descritos na literatura.ABESSapientiaIsidoro, JorgeSilveira, AlexandreLima, Bruno Oliveira2022-10-26T13:15:05Z20222022-01-01T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfhttp://hdl.handle.net/10400.1/18433eng1413-415210.1590/s1413-415220200365info:eu-repo/semantics/openAccessreponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAP2023-07-24T10:30:41ZPortal AgregadorONG
