DETERMINING IDF EQUATIONS FOR THE STATE OF RONDÔNIA

This study aimed to estimate the Intensity-Duration-Frequency (IDF) function of extreme pluviometric events for the State of Rondônia in Brazil. This study used forty-one pluviometric stations with over 10 years of historic data. Data were analyzed following the Gumbel distribution and related (thro...

Resumo:This study aimed to estimate the Intensity-Duration-Frequency (IDF) function of extreme pluviometric events for the State of Rondônia in Brazil. This study used forty-one pluviometric stations with over 10 years of historic data. Data were analyzed following the Gumbel distribution and related (through disaggregating of daily rains) to return periods comprising from 2 to 100 years and pluviometric durations from 5 minutes to 24 hours. Furthermore, areas of influence for the applicability of IDF equations were determined by Voronoi diagrams. The IDF equations were validated with the help of the regression coefficient (r²) and the Wilcoxon-Mann-Whitney hypothesis test showed that its use is feasible.
