Resumo: Extreme precipitation events cause severe damage in both urban and rural areas. The Ivaí river basin covers large differences in latitude, longitude and altitude, making its studies complex and necessary, besides being an important area of agricultural production The the aim of this work was to analyze the variability and tendency of the rainfall and its impacts through occurrences of floods, runoff and inundation episodes in the Ivaí river basin. To analyze trends, Linear Correlation (R²), Mann-Kendall Significance (MK Z) and Monotonic Trend (MK Tau) tests were used for the four seasons. As a result, it has been identified that summer and autumn are the seasons that had the most pronounced negative trends in rainfall, mainly in the southern and eastern portions of the basin. In addition, the occurrences of natural disasters caused by precipitation are alarming in the region, once 127 decrees of emergency.

La cuenca del río Ivaí cubre una amplia gama latitudinal, longitudinal y topográfica, lo que hace que sus estudios sean complejos y necesarios, así como un área importante de producción agrícola. El objetivo de este trabajo fue analizar la variabilidad estacional y la tendencia de la lluvia y sus impactos a través de la ocurrencia de de inundaciones, aluviones y diluvios en cuenca hidrográfica del río Ivaí. Para el análisis de la tendencia se utilizaron las pruebas de Correlación Lineal (R²) Mann-Kendall Significance (MK Z) y Monotonic Trend (MK Tau) para las cuatro estaciones del año. Se identificó que el verano y el otoño son las estaciones con las tendencias de lluvia negativas más pronunciadas, principalmente en las regiones sur y este de la cuenca. Si bien los desastres naturales relacionados con las precipitaciones son alarmantes en la región, se registraron 127 decretos de situaciones de emergencia.Os eventos extremos de precipitação causam severos danos no espaço urbano e rural. A bacia hidrográfica do Ivaí abrange uma grande amplitude latitudinal, longitudinal e topográfica, tornando seus estudos complexos e necessários, além de se uma importante área de produção agrícola. Objetivou-se neste trabalho analisar a variabilidade sazonal e a tendência pluviométrica e os seus impactos por meio de ocorrências de alagamento, enxurradas e inundações na mesma. Para a análise da tendência utilizou-se os testes de Correlação Linear (R²), Mann-Kendall Significance (MK Z) e a Monotonic Trend (MC Tau) para as quatro estações do ano. Identificou-se que o verão e o outono são as estações que tiveram as tendências pluviométricas negativas mais acentuadas, principalmente nas regiões sul e leste da bacia. Enquanto as ocorrências de desastres naturais vinculados à precipitação são alarmantes na região, ao todo 127 decretos de situações de emergência foram registrados.Universidade Estadual de Londrina2020-06-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionAvaliado pelos paresapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/geografia/article/view/3792110.5433/2447-1747.2020v29n2p123GEOGRAFIA (Londrina); v. 29 n. 2 (2020); 123 - 1422447-1747reponame:Geografia (Londrina)instname:Universidade Estadual de Londrina (UEL)instacron:UELporhttps://ojs.uel.br/revistas/uel/index.php/geografia/article/view/37921/27627Copyright (c) 2020 GEOGRAFIA (Londrina)http://creativecommons.org/licenses/by-nc/4.0info:eu-repo/semantics/openAccessde Moura, Denis Anderson VieiraCaldana, Nathan Felipe da SilvaEly, Deise Fabiana2022-09-20T15:40:13Zoai:ojs.pkp.sfu.ca:article/37921Revistahttps://www.uel.br/revistas/uel/index.php/geografiaPUBhttps://www.uel.br/revistas/uel/index.php/geografia/oairevista.geografia.uel@gmail.com||marcar@uel.br||laudi@uel.br2447-17470102-3888opendoar:2022-09-20T15:40:13Geografia (Londrina) - Universidade Estadual de Londrina (UEL)false
