- Abstract
In this paper, we present a regional analysis of maximum daily rainfall recorded by more than 2000 rain gauges in the Mexican Republic. The results allow to reliably estimate design storms for any watershed in Mexico. For the analysis we clustered 59 regions based on the terrain morphology and the way they are affected by extreme weather. Additionally the annual maximum daily precipitations were divided by their respective mean, resulting in samples with mean equal to 1 and standard deviation equal to the variation coefficient. To verify the homogeneity for each zone the Fisher test was considered, but taking in to account that such test is not strictly applicable to extreme distributions; it was also proposed to generate synthetic series to validate the variation coefficient behavior of the sample. To estimate the design storms, characteristic hyetographs were obtained for total durations higher or lower than one day.
