Susceptibility and Triggers for Debris Flows: Emergence, Loading, Release and Entrainmenta moving mass of loose mud, sand, soil, rock, water and air that travels down a slope under the influence of gravity. Flows can carry material ranging in size from clay to boulders, and may contain a large amount of woody debris. Volumes of material delivered by single events vary from less than 100

Sediment Transport Processesepancy between a surplus of sediments in upstream and a deficit in downstream river sections (Habersack et al. 2010b). This development leads to problems in flood protection (channel change), river engineering (e.g. riverbed degradation), hydropower generation (e.g. reservoir sedimentation) and the

Debris-Flow Runout and Deposition on the Fanor the prediction of flow and runout of debris flows have similarities to approaches originally developed for snow or debris avalanches and streamflow hydraulics (Körner 1980; Lied and Bakkehoi 1980; Perla et al. 1980; Iverson 1997). However, debris-flow volume and bulk flow behaviour may change dur

Hundreds of deaths occur every year, while horrific multi-thousand death tolls are announced every decade or so. Debris-flow related economic and life losses are not limited to emerging and developing countries but regularly occur in the developed world as well. In th

However, engineering hazard assessment of torrential processes is often limited to rough estimation of possible future events since the data base is

The prevalence of these landforms in these physiographic settings is attributed to rapid weathering associated with the presence of oversteepened valley sides, stress unloading o

Dendrogeomorphology – Tracking Past Events with Tree Ringsn sources are needed for an appraisal of past and contemporary as well as for the prediction of potential future events. Tree rings represent a very valuable natural archive on past torrential activity as they may record the impact of events in their tree-ring series. In the past few years, dendroge

Phytogeomorphology, the study of interdependence of vegetation and landforms (Howard and Mitchell 1985), has become a central topic in environmental studies (Hession et al. 2010; Marston 2010). According to a geo-ecologic approach (Troll 1971), this subject comb
