Resumo: This research aimed to analyze the distribution pattern and possible trends of average precipitation and maximum rainfall in 24 hours per year in the Pirapó-PR river basin. This basin is located in the Third Planalto Paranaense, between latitudes of 22º 30 ’and 23º 30’ South and longitudes of 51º15 ’and 52º15’ West. To carry out the research, the daily rainfall totals from 1980 to 2017 from 10 rainfall stations of the Instituto das Águas do Paraná - SIH were used. Descriptive statistics was applied to the rainfall data of the 10 pluviometric stations, using the respective parameters: mean, standard deviation and coefficient of variation. Through the Mann-Kendall (1975) non-parametric test, possible trends were verified in the annual series of average annual precipitation and maximum precipitation in 24 hours. The results showed that there is an increase in the distribution of average annual precipitation from the low to the high course of the basin, with the same pattern not being observed for similar daily maximum rainfall. The trend test showed signs of change in the behavior of the annual average values ​​of rainfall and daily maximum, but not significant.

Essa bacia está localizada no Terceiro Planalto Paranaense, entre as latitudes de 22º 30’ e 23º 30’ Sul e longitudes de 51º15’ e 52º15’ Oeste. Para a realização da pesquisa foram utilizados os totais pluviométricos diários de precipitação do período de 1980 a 2017 de 10 postos pluviométricos do Instituto das Águas do Paraná – SIH. Foi aplicada a estatística descritiva para os dados de pluviosidade dos 10 postos pluviométricos, utilizando-se os respectivos parâmetros: média, desvio padrão e coeficiente de variação. Por meio do teste não paramétrico de Mann-Kendall (1975), verificou-se possíveis tendências nas séries anuais da precipitação média anual e da precipitação máxima em 24 horas. Os resultados mostraram que há um aumento na distribuição da precipitação média anual do baixo para o alto curso da bacia, não sendo observado o mesmo padrão para a pluviosidade máxima diária semelhante. O teste de tendência demonstrou indícios de mudança no comportamento dos valores médios anuais de pluviosidade e máximos diários, porém não significativas.EDUFU - Editora da Universidade Federal de Uberlândia2022-04-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionAvaliado pelos paresapplication/pdfhttps://seer.ufu.br/index.php/caminhosdegeografia/article/view/5874410.14393/RCG238658744Caminhos de Geografia; Vol. 23 No. 86 (2022): Abril; 298-316Caminhos de Geografia; Vol. 23 Núm. 86 (2022): Abril; 298-316Caminhos de Geografia; v. 23 n. 86 (2022): Abril; 298-3161678-6343reponame:Caminhos de Geografiainstname:Universidade Federal de Uberlândia (UFU)instacron:UFUporhttps://seer.ufu.br/index.php/caminhosdegeografia/article/view/58744/33668Copyright (c) 2022 Silvia Mioto, Hélio Silveirahttp://creativecommons.org/licenses/by-nc-nd/4.0info:eu-repo/semantics/openAccessMioto, SilviaSilveira, Hélio2022-04-01T15:51:01Zoai:ojs.www.seer.ufu.br:article/58744Revistahttps://seer.ufu.br/index.php/caminhosdegeografia/indexPUBhttp://www.seer.ufu.br/index.php/caminhosdegeografia/oaiflaviasantosgeo@gmail.com1678-63431678-6343opendoar:2022-04-01T15:51:01Caminhos de Geografia - Universidade Federal de Uberlândia (UFU)false
