Resumo: Heavy rainfall extreme events are becoming increasingly significant and frequent in the climate change scenario. This work determined a new IDF equation for the Abaetetuba municipality (PA) from the historical rainfall series (1980 to 2019) obtained in the database of the National Water Agency. The data evaluated by the Filliben, Variance and Kolmogorov-Smirnov tests showed a Normal distribution with better fit considering the return periods 2, 5, 10, 50, 100, 200 and 1000 years. For the disaggregation of precipitation in lengths shorter than 1 day we used disaggregation coefficients recommended by the literature. Using two methods of non-linear regression in a comparative way were obtained coefficients of the equation: K (1197.6964), a (0.0933), b (10.9667) and c (0.7599). Comparing the present equation with the one described in previous work points to intensities overestimated by the old equation. Thus, the equation of intense rainfall updated for Abaetetuba will contribute to the more economical dimensioning of hydraulic-hydrological studies where it is necessary to determine the precipitation intensity.

En esto trabajo se determinó nueva curva IDF para la municipalidad de Abaetetuba (PA) a partir de la serie histórica de precipitaciones (1980 a 2019) obtenida de la base de datos de la Agencia Nacional del Agua. Los datos evaluados por las pruebas de Filliben, varianza y Kolmogorov-Smirnov indicaron distribución Normal con mejor adherencia considerando los períodos de retorno 2, 5, 10, 50, 100, 200 y 1000 años. Para la desagregación de la precipitación en duraciones menores a 1 día se utilizaron los coeficientes de desagregación recomendados por la literatura. Utilizando dos métodos de regresión no lineal de forma comparativa, se obtuvieron los coeficientes de la ecuación: K (1197,6964), a (0,0933), b (10,9667) y c (0,7599). La comparación de la curva actual con la descrita en un estudio anterior apunta a intensidades sobreestimadas por la curva anterior. Así, la curva de lluvias intensas actualizada para Abaetetuba contribuirá al dimensionamiento más económico de los estudios hidráulico-hidrológicos donde sea necesario determinar la intensidad de las precipitaciones.Eventos extremos de chuvas intensas estão se tornando cada vez mais significativos e frequentes no cenário de mudanças climáticas. Este trabalho determinou uma nova equação IDF para o município de Abaetetuba (PA) a partir da série histórica pluviométrica (1980 a 2019) obtida no banco de dados na Agência Nacional de Águas. Os dados avaliados pelos testes de Filliben, de Variância e de Kolmogorov-Smirnov apontaram distribuição Normal com melhor aderência considerado os períodos de retorno 2, 5, 10, 50, 100, 200 e 1000 anos. Para a desagregação da precipitação em durações menores que 1 dia se utilizou coeficientes de desagregação recomendados pela literatura. Usando dois métodos de regressão não linear de forma comparativa foram obtidos coeficientes da equação: K (1197,6964), a (0,0933), b (10,9667) e c (0,7599). O confronto da presente equação com a descrita em trabalho anterior aponta intensidades superestimadas pela equação antiga. Desta forma, a equação de chuvas intensas atualizada para Abaetetuba contribuirá no dimensionamento mais econômico de estudos hidráulico-hidrológicos onde seja necessária a determinação da intensidade de precipitação.Research, Society and Development2021-04-12info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/1421310.33448/rsd-v10i4.14213Research, Society and Development; Vol. 10 No. 4; e31310414213Research, Society and Development; Vol. 10 Núm. 4; e31310414213Research, Society and Development; v. 10 n. 4; e313104142132525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/14213/12723Copyright (c) 2021 Éverton Costa Dias; Giovanni Chaves Pennerhttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessDias, Éverton CostaPenner, Giovanni Chaves2021-04-25T11:21:26Zoai:ojs.pkp.sfu.ca:article/14213Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:35:23.398922Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false
