Climate change data
The Saône and Doubs watershed is a strategic territory. It is characterized by a rich diversity of water uses and sensitive aquatic environments. Against a backdrop of climate change, this region is exposed to numerous climatic phenomena. These phenomena can include flooding and prolonged drought, putting pressure on water resources.
The Établissement Public Territorial du Bassin Saône et Doubs has initiated a prospective study. The aim is to analyze the impact of climate change on water resources and propose sustainable adaptation strategies for the future. The study is based on a rigorous procedure designed to provide a clear vision of the challenges ahead. This study of the impact of climate change on hydrology integrates the climatic, hydrological and socio-economic dimensions specific to this basin.
The main objective is to quantify the impacts of climate change on hydrology and water uses. This must be done while identifying the necessary adaptation strategies. The study addresses several key issues:
This first stage in the impact of climate change on hydrology is based on the collection and synthesis of existing data. These include data on climatology, hydrology and water use in the basin. Previous studies, technical reports and local data are integrated to provide a comprehensive overview. The division of the territory into coherent geographical sectors is a key component of this phase. This enables us to take into account local particularities.integrated to draw up an exhaustive inventory.
These areas include those regularly affected by flooding. They also include areas where groundwater is essential. Last but not least, they include areas with a high level of agricultural activity. This step highlights the priorities and critical points to be addressed in subsequent phases. This is achieved by combining this segmentation with a detailed cartographic analysis.
This phase examines the evolution of past climatic and hydrological conditions. This stage is essential for understanding the trends influencing water resources and uses. The main parameters studied include :
This analysis is based on reliable historical data spanning several decades.
In the third stage, we will analyse the climate and hydrological projections from EXPLORE2. Two scenarios will be explored:
Climate and hydrological projections are analyzed for three time horizons: 2035, 2050 and 2070. Key variables are analyzed to assess future impacts on aquatic environments and water uses. These variables may be river flows, maximum rainfall or the frequency of extreme events, for example.
Territory-specific simulations are carried out to evaluate different adaptation scenarios. For example, the results allow us to distinguish impacts depending on whether integrated resource management is implemented or not. These analyses underline the crucial importance of a well-thought-out, anticipatory management strategy to minimize the consequences of climate change.
The results will provide a solid basis for :
This study is an essential step towards anticipating the impacts of climate change on the Saône and Doubs basin. This analysis provides decision-makers with concrete tools for taking action today. Indeed, by combining the analysis of historical data, future projections and detailed risk mapping, it becomes a real tool. This case study is an integral part of our water resources data service.
Based on this technical foundation, EPTB Saône et Doubs will be able to take targeted action to protect water resources, adapt infrastructures and guarantee balanced management of uses in a changing climate.
