| Description: |
International audience ; This work aims to present a panel of numerical modeling studies on groundwater resource issues in the northern part of France (the 'Hauts-de-France' Region), covering various contexts and applications such as urban hydrogeological systems, land use evolution, and the impact of climate change on river watersheds. Our objective is to demonstrate the capabilities and limitations of modeling tools in reproducing observed data and providing predictions regarding the evolution of water tables under increasing anthropogenic pressures and natural climate change. Numerical models are developed in 3D at the regional scale to assess various groundwater management scenarios, taking into account different types of anthropogenic or natural constraints, such as pumping for irrigation, drinking water and/or industrial use, land use changes, and modifications in precipitation and/or evapotranspiration due to climate change.The three case studies presented utilize the in-house 3D volume finite numerical tool MARTHE. The first case aims to characterize groundwater dynamics to identify flood risks in the sewerage network of the urban communities of Lens-Liévin. The second case explores the role of land use in groundwater modeling for the sustainable management of the Lille Metropolitan Area. The third case evaluates the impact of climate change on the groundwater resources of the Somme River watershed.Limitations and capabilities for assessing such complex hydrogeological systems are discussed, particularly concerning the level of uncertainty in the simulated results and the CPU time and spatial resolution constraints necessary for meaningful calibration of observed data.Perspectives on the development of regional-scale numerical models are discussed through the deployment of a simulation platform compiling 3D numerical models developed at the national scale. |
