Resumo: The need for information on rainfall of certain durations and frequencies is very large in various hydraulic designs. Thus, the objective of this work is to adjust the cumulative Gumbel probability function to obtain the maximum expected precipitation intensities for different return periods, obtaining the intensity-duration-frequency equation by means of the isozone method for maximum annual daily rainfall data. In this case, the rainfall data from the Newton Belo rainfall gauge station between 1985 and 2013 were adopted. A series of maximum rainfall intensity for one day of precipitation was elaborated using the Gumbel methodology. The extreme values for the return periods of 5, 10, 20, 30, 50 and 100 years were estimated by the isozone method, adjusting the IDF curve, which was compared to IDF curves of the Northeast and Southeast region of Brazil, showing good estimate for rainfall intensities. This comparison suggests that the generated equation can be used to calculate the maximum rainfall intensity with different durations and return periods for hydraulic and water resources engineering studies in the Governador Newton Bello region.

Por lo tanto, el objetivo de este trabajo es ajustar la función de probabilidad acumulativa de Gumbel para obtener las intensidades de precipitación máximas esperadas para diferentes períodos de retorno, obteniendo la ecuación de intensidad-duración-frecuencia mediante el método de isozona para datos de precipitación diaria máxima anual. En este caso, se adoptaron los datos de lluvia de la estación de pluviómetros Newton Belo entre 1985 y 2013. Se elaboró una serie de intensidad de lluvia máxima para un día de precipitación utilizando la metodología Gumbel. Los valores extremos para los períodos de retorno de 5, 10, 20, 30, 50 y 100 años se estimaron mediante el método de la isozona, ajustando la curva IDF, que se comparó con las curvas IDF de la región noreste y sureste de Brasil, mostrando una buena estimación de las intensidades de lluvia. Esta comparación sugiere que la ecuación generada puede usarse para calcular la intensidad máxima de lluvia con diferentes duraciones y períodos de retorno para estudios de ingeniería hidráulica y de recursos hídricos en la región del Governador Newton Bello.A necessidade de informações sobre as precipitações de determinadas durações e frequências é muito grande em projetos hidráulicos diversos. Assim, o objetivo do trabalho é ajustar a função cumulativa de probabilidades de Gumbel para se obter as intensidades máximas de precipitações esperadas para diferentes períodos de retorno, obtendo-se a equação de intensidade-duração-frequência, por meio do método das isozonas, para dados de precipitação máxima diária anual. Nesse caso, foram adotados os dados pluviométricos da estação pluviométrica Newton Belo no período entre 1985 e 2013. Uma série de máxima intensidade pluviométrica para um dia de precipitação foi elaborada, utilizando-se a metodologia de Gumbel. Os valores extremos para os períodos de retorno de 5, 10, 20, 30, 50 e 100 anos foram estimados, pelo método das isozonas, ajustando-se a curva IDF, que foi comparada a curvas IDF da região nordeste e sudeste, demonstrando boa estimativa para as intensidades de chuvas. Essa comparação sugere que a equação gerada pode ser utilizada para o cálculo da intensidade máxima de chuvas com diferentes durações e períodos de retorno para estudos de engenharia hidráulica e de recursos hídricos na região de Governador Newton Bello.Research, Society and Development2020-01-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/237410.33448/rsd-v9i3.2374Research, Society and Development; Vol. 9 No. 3; e39932374Research, Society and Development; Vol. 9 Núm. 3; e39932374Research, Society and Development; v. 9 n. 3; e399323742525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/2374/1893Copyright (c) 2019 Basílio Rocha Neto, Claudio Blancoinfo:eu-repo/semantics/openAccessNeto, Basílio Pires RochaBlanco, Claudio José Cavalcante2020-08-20T18:07:57Zoai:ojs.pkp.sfu.ca:article/2374Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:27:01.199361Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false
