Abstract

This paper studies the Intensity-Duration-Frequency relationship of rainfall for the city of Chapecó, Santa Catarina State, Southern Brazil. High rainfall, with duration from 5 to 1440 minutes was studied and three equations to predict the rainfall intensity were adjusted: one for rainfall with duration below 120 minutes, another for durations between 120 and 480 minutes and the third for durations from 480 to 1440 minutes. It was also defined the relationship between several rainfall durations. Variation was observed between 24-hour rainfall and one-day rainfall, depending on the hour in which the samples were collected.
