Résumé

The semi-arid Mediterranean climate exhibits pronounced spatio-temporal variability, particularly with regards to rainfall. This makes the Cap-Bon peninsula of northeastern Tunisia, the region of interest for this study, inherently prone to cyclical droughts and floods. Understanding past variations in climate and predicting future ones has thus become essential for enhancing the capacity of national and regional governments and other stakeholders to plan climate change adaptation measures. A coupled hydrological model (CATHY) is used to investigate, for a range of climate change scenarios, the spatio-temporal patterns of response variables such as groundwater recharge, water levels, and streamflow of the Chiba catchment (200 km2). Runs of the model assume the emission scenario A1B proposed by the Intergovernmental Panel on Climate Change (IPCC) from 1951 to 2100 at a daily scale. The work will also address issues of uncertainty arising from input data and model parameterization errors and biases. A multi-model framework for uncertainty reduction whereby CATHY simulation results will be analyzed in tandem with those obtained from two other models (WaSiM and SWAT) will also be discussed.
