Abstract

The bibliographical analysis of the various models of calculation of the flows of storm water, it appears obvious that the curves Intensities-Durations-Frequencies, are the key elements in all the dimensioning of work relating to the cleansing, of this fact it is necessary to control the phenomenon of rain before the construction of the model of calculation of the peak flow or the construction of the hydrograph resulting at the exutoire of the catchment area. We were interested in the project rainfall to be used for different studies. It was necessary to process the available rainfall data, to be able to determine the rainfall parameters for the ANNABA region.
