Debris flow activity in a changing climate: Insights from the SEHAG project.

Moderation: Prof. Dr. Achim Bräuning
The interdisciplinary and international research group SEHAG (Sensitivity of High Alpine Geosystems to climate change since c. 1850) is investigating how climate change has influenced hydrological, glaciological, botanical, climatological, and geomorphological systems in the Alps. Within this framework, I will present results on debris flow activity in high alpine environments since the end of the Little Ice Age, around 1850.
Debris flows are a significant geomorphic process and occur as a natural hazard in mountainous regions worldwide, playing a key role in sediment dynamics of alpine catchments. Understanding how their frequency and magnitude have evolved under a changing climate is essential for both scientific insight and practical risk management. However, comprehensive long-term records of debris flow activity are scarce.
In this talk, I will present the findings from our study in the Horlachtal, Tyrol (Austria), where we reconstructed a debris flow chronology spanning the past 170 years. By integrating remote sensing methods—such as aerial photography and LiDAR—with lichenometric dating, we have been able to identify and date recent as well as historical debris flow deposits. These results provide valuable perspectives on the temporal dynamics, triggers, and geomorphological significance of debris flows in the context of ongoing climate change.
