Between 2016 and 2020, the Cévennes National Park and BRGM worked together on a hydrogeological study of the Méjean Causse.
Water is an essential resource with many uses, including drinking water supply, tourism and agriculture. Today, water needs are expanding to cater for the growth of human settlement and activity in the area, while climate change seems to be reducing rainfall, leading to an imbalance, especially in the summer when needs are greatest. Water resources are therefore a major issue for regional and local development, particularly as the levels of abstraction must not impact the ecology of aquatic ecosystems.
The aim of the study was to improve our understanding of groundwater flow processes on this large limestone plateau, to be able to meet the increasing need for high-quality water and sustainably manage this valuable, yet scarce resource.
Conference – Thursday 10 March 2022
The main results of the study will be disclosed at a conference on Thursday 10 March 2022 from 18.00 to 20.00 at the Genette Verte centre – Florac-Trois-Rivières.
The study leaders will give presentations on the following topics:
- Exploring the ancient Grands Causses landscape
- The journey of a drop of water from groundwater resource to surface water resurgence
- Water resource vulnerability and contamination risks
Time will be allowed during the conference presentations for discussions and questions from the public.
Places are limited and registration is required.
A valid health pass is required to attend.
