Soil wetness measurements are used for shallow landslide prediction; however, existing sites are often located in flat terrain. Here, we assessed the ability of monitoring sites at flat locations to detect critically saturated conditions compared to if they were situated at a landslide-prone location. We found that differences exist but that both sites could equally well distinguish critical from non-critical conditions for shallow landslide triggering if relative changes are considered.

Soil moisture information was shown to be valuable for landslide prediction. Soil moisture was simulated at 133 sites in Switzerland, and the temporal variability was compared to the regional occurrence of landslides. We found that simulated soil moisture is a good predictor for landslides, and that the forecast goodness is similar to using in situ measurements. This encourages the use of models for complementing existing soil moisture monitoring networks for regional landslide early warning.

The sources of stream water are important, for instance, for predicting floods. The connectivity between streams and different (ground-)water sources can change during rain events, which affects the stream water composition. We investigated this for stream water sampled during four events and found that stream water came from different sources. The stream water composition changed gradually, and we showed that changes in solute concentrations could be partly linked to changes in connectivity.

Short summary
Due to climate change, the hazard for debris flows originating in glacier forefields or areas dominated by seasonal to perennial frost is increasing. Hazard assessment for this type of debris flows is especially difficult as records of past events are typically scarce or inexistent. We therefore developed a multi-methods approach for scenario building and runout modelling for pro- and periglacial debris flows triggered by precipitation events and applied it to a catchment in the Swiss Alps.

Debris flows are complex, surging movements of sediment and water. Discharge observations from well-studied debris-flow channels were used as inputs for a numerical modelling study of the downstream effects of chaotic inflows. The results show that downstream impacts are sensitive to inflow conditions. Inflow conditions for predictive modelling are highly uncertain, and our method provides a means to estimate the potential variability in future events.

The open-source fluid dynamic solver presented in v. Boetticher et al. (2016) combines a Coulomb viscosplastic rheological model with a Herschel–Bulkley model based on material properties for 3-D debris flow simulations. Here, we validate the solver and illustrate the model sensitivity to water content, channel curvature, content of fine material and channel bed roughness. We simulate both laboratory-scale and large-scale debris-flow experiments, using only one of the two calibration parameters.

The erosion of and depositions on channel bed surfaces are instrumental to understanding debris flow processes. We present different methods and highlight their pro and cons. Terrestrial and airborne laser scanning, erosion sensors, cross sections and geomorphological mapping are compared. Two of these approaches are tested and applied in a torrent. The results indicate that the methods are associated with variable temporal and spatial resolution as well as data quality and invested effort.

In this paper we used two different numerical simulation models to replicate two debris-flow events in Austria and compare the range and sensitivity of the model input parameters. We expect that our results contribute to a better application of simulation models for hazard and risk assessment in alpine regions.

Soil quality depends on water availability for plants. Sandy soils with a poorly permeable layer (fragipan) are considered inept for agriculture. However they are cultivated in Namibia as they secure a minimum harvest during droughts. In order to understand the hydrological influence of fragipans in these soils, soil moisture content was measured. The results illustrate that the combination of sandy topsoil and shallow fragipan has beneficial effects on plant-available water during dry periods.

The Monte Crenone rock avalanche of 1513 is well known on the southern side of the Alps because in 1515 it generated the largest inundation that has occurred in Switzerland in the Common Era, the Buzza di Biasca. New geological and historical observations allowed the setup of a numerical model of this major event, permitting a better definition of the chain of consequences that affected the alluvial plain of the river Ticino from Biasca to Lake Maggiore between the 16th and the 19th century.

The paper presents the results of recent geoarchaeological studies on the Ticino river alluvial plain. The sedimentological descriptions are combined with archaeological observations and constrained with radiocarbon dating. This approach, together with data from previous research and historical sources, provides an interesting overview of the eveolution of Ticino river morphosedimentary dynamics in relation to human settlements since the Neolithic.

Exposure ages make it possible to determine the time of weathering of a rock surface. They can be determined from rebound values measured with the Schmidt hammer and calibrated on surfaces of known age, defined in this study thanks to historical cartography and two mule tracks built in 300 and 1250 CE, which allowed us to reconstruct glacier fluctuations over the last 3 centuries in Val Scaradra and to define the time of deglaciation and rock glacier development in the Splügenpass region.

In mountain environments, active geomorphological processes have a strong influence on plant diversity because they act as renovators for habitats of pioneer species. In this paper, we propose criteria to assess the ecological value of dynamic mountain geomorphosites. We show that the interest of plant communities and the influence of geomorphological processes on plant communities are fundamental criteria for assessing ecological value in an exhaustive and objective way.

Soil erosion by wind and water is a commonly recognized phenomenon on agricultural land. Erosion in forests is studied less and generally considered to be limited because of the soil protection by vegetation. However, trees, when toppled because of old age or wind, loosen a considerable amount of soil when their roots are pulled from the ground. In addition, the holes left in the ground act as collectors for water and concentrated runoff, causing significant soil loss on forested slopes.

This article studies the ice flow in the Valais region during the last glaciation (Würm) in detail. The numerical modelling shows a discrepancy of the height of the ice cap compared to the geomorphological evidence based on trimlines. However, geomorphological evidence at the Simplon Pass indicating an ice flow from the Rhone valley into the valley of Toce was confirmed. Furthermore it is shown that for this confirmation a sufficient ice thickness is obligatory.

During the last 45 years, about 100 people lost their lives in avalanches in the European Alps each year. Avalanche fatalities in settlements and on transportation corridors have considerably decreased since the 1970s. In contrast, the number of avalanche fatalities during recreational activities away from avalanche-secured terrain doubled between the 1960s and 1980s and has remained relatively stable since, despite a continuing strong increase in winter backcountry recreational activities.

In the scientific literature, “protalus ramparts” can designate both a nivo-gravitational landform (also called “pronival ramparts”) and a permafrost-related landform. Thanks to a selection of eight major diagnostic criteria defined from observations carried out in the Swiss Alps, it was highlighted that the structure, ice content and creep dynamics of protalus ramparts are the same as many rock glaciers. Protalus rampart were therefore defined simply as a (small) active talus rock glacier.

Short summary
Short summary
Alpine and mountain slopes represent important pathways that link high-altitude grazing areas to meadows and rangelands at lower elevations. Given the acute gradients associated with such environments, we hypothesize that terracettes act as efficient runoff conveyance routes that facilitate the movement of runoff and associated material during erosion events. This hypothesis was partially disproved during a series of rainfall/runoff simulations on a well-developed terracette system, however.
