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

Events on Fans and Cones: Recurrence Interval and Magnitudeesult in most losses worldwide. 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

Silent Witnesses for Torrential Processesocated on Alpine fans. Protection works and mitigation measures are mostly based on the magnitude of a design event with a defined recurrence interval. However, engineering hazard assessment of torrential processes is often limited to rough estimation of possible future events since the data base is

The Use of Airborne Laser Swath Mapping on Fans and Cones: An Example from the Colorado Front Rangetains of the lower latitudes (Rapp 1960a, b; Albjar et al. 1979; Church et al. 1979; White 1981; Caine 1983; Perez 1993). 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

Tree-Ring Based Record of Debris-Flow Dynamics and Triggering Rain Storms at Ritigraben (Swiss Alps)rom its confluence with the Vispa River at 1,080 m asl to the summit of the Seetalhorn (3,100 m asl). A rock glacier occupies most of the headwater basin (1.4 km.) between 2,500 and 2,800 m asl (Fig. 1a), constituting the main starting zone of debris flows. On its downward course to the Mattervispa

Vegetation Analysis on Composite Debris Cones002; Pignatti et al. 2005; Huc 2008). 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
