Abstract

This study analyzes the concentrated pluviometric events, focalizing the pluvial impacts on Cajuru quarter, in CuritibaPR-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.
