The purpose of this study is to update the rainfall intensity-duration-frequency curves. In this perspective, annual maximum series of 13 synoptic stations have been analyzed over the period 1955 to 2001. The statistical analysis shows that most series are well fit by the Gumbel and the Lognormal distributions. The parameters of Montana model obtained by this present study are well above those currently used by engineers for the design of urban drainage systems. The values of the parameters have doubled or even tripled in some cases. The previous intensity-duration-frequency curves underestimate the maximum intensities of rainfall durations lower than 20 min and overestimate those exceeding 20 min. These changes in the parameters of Montana and the intensity-duration-frequency curves certainly have an impact on the design of hydraulic structures and roads. |
