Contribution à l’étude des déférentes méthodes d'estimation de l’intensité pluviales.

Abstract

According to the literature review, the design and sizing of hydraulic structures requires knowledge of the estimated rainfall for the appropriate failure period of the structures and, consequently, knowledge of the hydrological response of the watershed to this rainfall. The rainfall model, intensity-duration-frequency (IDF) curves, remains the most common statistical approach to establish the rainfall-flow relationship. The objective of this study is to plot the Intensity-Duration-Frequency (IDF) curves of the Keddara region using four models for the development of IDF curves for this region. These models allow us to determine the theoretical intensity which will be compared to the real intensity.
