Résumé:
Caractériser l’hydrologie des bassins méditerranéens pour les besoins de la gestion de la ressource en eau et l’étude de l’impact des changements climatiques:
- Quelle contribution du climat et du paysage en hydrologie ?
- Quelle répartition spatiale des ressources en eau ?
- Quels sont les bassins similaires, homogènes ?
- Quels impacts du changement climatique ? Abstract:
Mediterranean water resources are more than ever exposed to the increasing demand of demographic and climatic evolution. To better understand these challenges, this thesis aimed to collect a Mediterranean hydrological database, establish a new climatic classification for hydrology purposes, identify the physiographic variability, and analyze the hydrological balance of 55 catchments according to different
functional models. We have established 5 climatic classes, 10 physiographic classes and identified the general intra-climate hydrological homogeneity and inter-climate homogeneity, especially in the case of mountainous karstic catchments under snow influence. The impact of climate change, indicated an evolution of the Mediterranean region towards the arid climate with the northern catchments in slow translation towards the moderate southern catchments which could affect hydrological regimes and agricultural practices, due to the shorter wet seasons and early snowmelt.
