The PDF version of the dissertation can be downloaded here and the presentation slides in French are available here. Moreover, the decomposition of the flood-producing factors proposed by the SCHADEX method has been used for considering different simulated climatic evolutions and for quantifying the relative impact of these factors on the extreme flood estimation. New climate model outputs done within the CMIP5 project have been analyzed and used for determining future frequency of rainfall events and future catchment saturation conditions. Using the sensitivity analysis results, tests have been done in order to estimate the future evolution of “key” variables previously identified. In a context of potential increase of extreme event intensity and frequency due to climate change, the use of the SCHADEX method in non-stationary conditions is a main interest topic for EDF hydrologists.

Even if the extreme flood estimation sensitivity analysis has raised numerous questions about the rainfall-runoff model calibration within the SCHADEX method, quantifying the future rainfall event intensity is the key question for the extreme rainfall and flood predetermination in a climate change context. This last test showed the difficulty to quantify the impact of climate change on extreme floods due to a combination of extreme flood decrease factors extreme flood decrease due both to future rainfall event frequency and catchment saturation condition evolution and extreme flood increase factor extreme flood increase due to an increase of future rainfall event intensity. Thus, the scientific goal of this Ph. Nevertheless, supplementary tests are needed in order to estimate the timestep and the temperature range at which this rainfall event intensity increase is valid. A sensitivity analysis allowed to quantify the extreme flood estimation sensitivity to rainfall hazard, catchment saturation hazard and rainfall-runoff transformation, independently.

Even if the extreme flood estimation sensitivity analysis has raised numerous questions about the rainfall-runoff 22013 calibration within the SCHADEX method, quantifying the future rainfall event intensity is the key question for the extreme rainfall and flood predetermination in a climate change context.

Moreover, the decomposition of the flood-producing factors proposed by the SCHADEX method has been used for considering different simulated climatic evolutions and for quantifying the relative impact of these factors on the extreme flood estimation. New climate model outputs done within the CMIP5 project have been analyzed and used for determining future frequency of rainfall events and future catchment saturation conditions.

The recognized inabilities of climate models and downscaling methods to simulate extreme rainfall distribution at the catchment-scale have been avoided, by developing and testing new methodological approaches.

French national chtaou of geodesy and geophysics.

In order to predict the future intensity of rainfall events with air temperature simulated series, tests have been performed on several hundred of French catchment rainfall series, trying to link observed air temperature with observed rainfall event intensity. Nevertheless, supplementary tests are needed in order to estimate the timestep and the temperature range at which this rainfall event intensity increase is valid.
