IMPACTOS PLUVIAIS NO BAIRRO CAJURU – CURITIBA – PR (pluvial impact on Cajuru district – Curitiba - PR)
Abstract
Este estudo analisa os eventos pluviométricos concentrados, enfocando os impactos pluviais no bairro Cajuru, em Curitiba - PR, dentro da perspectiva do Sistema Clima Urbano, subsistema hidrometeórico de Monteiro (1976, 2003). Consiste em identificar a ocorrência de totais pluviométricos diários iguais e superiores a 60 mm, dentro do município de Curitiba e Colombo, este último contendo as nascente do rio Atuba, o que influencia no bairro aqui estudado. Analisa ainda, as vazões do rio Atuba, bem como as tendências das mesmas para as duas últimas décadas. Os resultados apontam vários eventos com magnitudes superiores a 100mm diários, que geraram inúmeros impactos no bairro cajuru. As vazões do rio mostraram um considerável aumento no decorrer dos anos, muito provavelmente em virtude das mudanças do uso do solo na bacia do rio Atuba e na área específica de estudo.
Palavras-chave: eventos pluviométricos concentrados, impactos pluviais, vazões.
ABSTRACT
This study analyzes the concentrated pluviometric events, focalizing the pluvial impacts on Cajuru quarter, in Curitiba-PR-Brazil, in the perspective of the Urban Climate System, subsystem hydrometeoric of Monteiro (1976, 2003). It consists in identifying the occurrence of daily pluviometric totals equal and superior to 60 mm, in the municipalities of Curitiba and Colombo, this last one containing the headwaters of Atuba river, which influences the quarter that we are studying. It analyzes yeat, the outflows of Atuba river, and also its tendencies for the last two decades. The results point out many events with magnitudes higher than 100 mm daily, which generated many impacts on Cajuru quarter. The river outflows showed a considerable increase in the course of the years, probably because of the changes in the use of the soil in the basin of Atuba river and in the specific area of study.
