Estimation des crues rares et extrêmes : principes du modèle AGREGEE

Abstract : The Agregee model, which is a generalization of the gradex model, is designed to estimate the flood frequency curve, for a given duration d, using a combinaison of observed flow and rainfall, and historical information. The main parts of the model are the fitting of rainfall and discharge distributions, the use of a simple mathematical formulation which allows a progressive extrapolation of the discharge distribution, and the calculation of bivariate distributions in order to estimate the peak discharges. The model allows us to build synthetic monofrequency hydrographs.
