In june 2025, BRGM published a modernized version of the MeteEAU Nappes web application.
This version responds to the expected changes from a graphical and functional point of view, and the needs of different users (accessibility, ergonomics...).
This redesign show a tool with a user-friendly interface, aesthetic, modern, clean, practical, responsive design, understandable and easy to use.
Now, the application shows the french national groundwater bulletin.
The application is open access.
Water experts will access to advanced options (restricted features, confidential models) after login via their own account (with email and password)*.
(*): As the modernized version of the web application uses the new Keycloak authentication system, users will need to validate their account through this software.
