Rene-Levesque Quest, Montreal (Quebec), Introduction In order to carry out the design of hydraulic structures, the management and rational operation of reservoirs as well as flood predictions, it is important to adequately estimate extreme flows in general or floods with a given return period Tin particular, such that: where p is the exceedance probability associated with the hydrological risk (Kite [3]). The fitting of statistical distributions to annual maximal flows is a common tool for determining x^ and its confidence intervals. The first part of this paper presents the software Aju
