Zusammenfassung |
Recent warming has had enormous impacts on glaciers and high-mountain
environments. Hazards have changed or new ones have emerged, including those
from glacier lakes that form as glaciers retreat. The Andes of Peru have
repeatedly been severely impacted by glacier lake outburst floods in the
past. An important recent event occurred in the Cordillera Blanca in 2010
when an ice avalanche impacted a glacier lake and triggered an outburst
flood that affected the downstream communities and city of Carhuaz. In this
study we evaluate how such complex cascades of mass movement processes can
be simulated coupling different physically-based numerical models. We
furthermore develop an approach that allows us to elaborate corresponding
hazard maps according to existing guidelines for debris flows and based on
modelling results and field work. |
