Sauquet, E. /Tramblay, Yves extreme rainfall extreme flood reliability stability comparison of methods predictive distribution This paper presents a comparison of models for extreme rainfall and flood values. Based on a large set of thousands of rainfall and discharge data, the French ExtraFlo project showed that design estimate of extreme values based on the fitting of a distribution on a limited sample of maximum values is very inaccurate when only a few decades of observation are available. Some interesting alternatives are possible, using a regional approach, or historical data when available, or simulation methods, or sedimentological or geochemical signatures of flood deposits. 2014 text https://www.documentation.ird.fr/hor/fdi:010062075 fdi:010062075 Lang M., Arnaud P., Carreau Julie, Deaux N., Dezileau L., Garavaglia F., Latapie A., Neppel L., Paquet E., Renard B., Soubeyroux J.
