- Abstract
- Water resources in Tunisia are limited in space and time. With an annual average of less than 500 mɜ per inhabitant, Tunisia is classified as a water-poor country. On the other hand, the hydro-climatic models predict a reduction in water availability, yet limited, with exacerbated forms of pollution as a result of both climate and land use/cover changes. However, how climate and land use changes will affect the hydrological cycle at the catchment scale in Tunisia is still not clear and remain among the challenges that hydrologists are still facing and trying to arise. The challenges for assessing the combined effect of changes in climate and land use on the catchment flow regime stem from the lack of scientific knowledge regarding the hydro-climate processes and their representation into a model or a set of models to accurately simulate the actual natural processes. Indeed, hydrological impacts of climate and landuse changes are prone to uncertainty. The latter needs to be appropriately addressed and the hydrological projections also should be communicated with uncertainty. However, there is no a common toolkit or approach to address the combined impacts of climate and landuse change on catchment hydrology within an uncertainty framework. Therefore, in this project I am aiming to develop a modeling platform that combines both climate and hydrological models. Based on historic knowledge and future projections, model projection underpinned with landuse and water management scenarios will guide to develop a decisional supporting system tool that will assist water management process under changing climate and landuse conditions.
