Recherche bibliographique sur la conception des bassins de retenue d'eaux pluviales.

Abstract

The problem of flooding in pre-urban has always preoccupied the local authorities and the populations subject to this permanent threat during the rainy season. To contribute to the resolution of this problem we opted by the procedure of regulation of the flows that is to say the continuous and diffused retention leading to a reduction of the peak flows. Thus, the rainfall method was used to estimate the volumes required for retention by the retention structure. This method allowed us to evaluate the specific storage height from a simple graphical construction.
