Short summary

This study examines the evolution of the lower Bruche River valley in north-eastern France through its fluvial terraces, reflecting past river dynamics and environmental changes. Terrace formations are dated using luminescence to ~ 12–14 ka, ~ 27–35 ka, and at least 200 ka. Methodological improvements over conventional luminescence dating techniques are also discussed and refined in this study.
