Développement des courbes IDF dans la région centre ville de Soumaa, Mouzaia et Oued Zeboudj.

Abstract

This study aims to modeling IDF curves through the stations of Mouzaia and Soumaa located in full Mitidja where the terrain is almost flat, including the station of Oued Zeboudj where the altitudes are low. The presence of short rainfall series "for each time step" to Mouzaia and Soumaa urges us to apply the frequency analysis based on the series of partial durations "or higher threshold" which presents an advantage over the series of annual maxima in if the latter have several missing data. Four models will be used for the development of IDF curves for these three stations, namely: The model of Talbo "two-and three-parameter", Montana, and the model of Kheifer Chu. A comparative study is needed to choose the best model that presents the least error in reporting the actual intensities. At the end, we present the generalized formulas of IDF curves for these three stations.
