IDF curves on central-south Chile

Roberto Pizarro, Pablo García-Chevesich, Francisco Balocchi, Rodrigo Valdés

Research output: Chapter in Book/Report/Conference proceedingChapterpeer-review


As a way to contribute to proper use of IDF curves in Chile, this chapter describes the relationship among four crucial climatic variables: rainfall intensity, storm duration, rainfall frequency and rainfall distribution. Graphical and mathematical representations of IDF curves were developed towards the selection of 1-, 2-, 6-, 12-, and 24-hr duration maximum rainfall intensities, the use of probability distribution functions, and their respective goodness of fit tests. Additionally, maximum rainfall intensities were analyzed by the graphical comparison of 5- and 100-year return periods. Even though total rainfall gradually increase from north to south, maximum rainfall intensities remin constant towards the country. However, maximum rainfall intensities signifificantly change near large bodies of water, such as lakes and reservoirs.
