Abstract

This study had the objective of obtaining rain intensityduration- frequency information for some sites in the State of Goiás and Distrito Federal, using the one-day rain disaggregation method. The precipitation intensities obtained through the equations generated in this paper were compared to those obtained by adjusted equations based on pluviographic data. The intensityduration-frequency relationships generated through pluviometric data using the one-day rain disaggregation method presented relative mean deviations varying between -1.6% and 43.9%, for some municipalities in this region. This limits its use in sites where regression equations were not adjusted.

KEY-WORDS: Intense rainfall; drainage; intensity-durationfrequency.
