THESIS 2013 CHATOU

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. 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. 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. Using the sensitivity analysis results, tests have been done in order to estimate the future evolution of “key” variables previously identified. French national comity of geodesy and geophysics. A sensitivity analysis allowed to quantify the extreme flood estimation sensitivity to rainfall hazard, catchment saturation hazard and rainfall-runoff transformation, independently. Nevertheless, supplementary tests are needed in order to estimate the timestep and the temperature range at which this rainfall event intensity increase is valid.

Using the sensitivity analysis results, tests have been done in order to estimate the future evolution of “key” variables previously identified. 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.
