ERT measurements typically use conventional steel electrodes in combination with a water-soaked sponge. However, ensuring an optimum contact resistance between the electrodes and the ground to obtain high-quality data is often challenging and requires considerable logistical, physical, and time commitment. To overcome this, we tested a promising sand-filled, fist-sized conductive textile electrode. We conducted ERT measurements using both steel and textile electrodes at a landslide and two rock glaciers in the European Alps with coarse blocky surfaces and performed statistical analyses to test the accuracy and precision of the proposed textile electrodes. Our results show that the textile electrodes can be used as an alternative to the conventional steel electrodes without limitations, as they ensure good galvanic contact with the ground and accurate resistivity measurements. The use of textile electrodes also resulted in lower contact resistances, less time invested, physical and logistical advantages, and reduced risk of injury. In the future, this will enable applications such as enhanced ERT monitoring and/or faster (quasi-3D) imaging of the interior of entire landforms."},{"pid":"wsl:39458","object_url":"https://www.dora.lib4ri.ch/wsl/islandora/object/wsl:39458","citation":{"WSL":"Bebi P., Lange B., Allgaier Leuch B., Losey S.

The experiments focused on evaluating the influence of water content, initial volume, and grain size distribution on debris flow dynamics. Debris flow experiments reveal that small changes in water content can trigger abrupt transitions in flow regimes, significantly altering runout distances and deposition patterns. Additionally, dimensionless parameters were calculated to characterize flow regimes, and granulometric analysis was performed on the deposited material. The results show that runout distance and deposition area increase with higher water content and larger initial volumes, whereas finer content reduces runout. Granulometric analysis revealed a clear segregation of coarse particles, with enrichment at the margins and towards the flow front, indicating that coarse particles enhance the destructive potential of debris flows. Dimensionless analysis identified the experimental flows as predominantly frictional in nature. The findings demonstrate consistency with natural debris flows and align with global experimental studies, providing valuable insights into the behavior of debris flows in the Indian Himalayas. Despite limitations due to scaling effects and reconstruction challenges, this study highlights the importance of experimental approaches in advancing our understanding of debris flows, particularly in regions lacking extensive historical data and monitoring infrastructure."},{"pid":"wsl:38186","object_url":"https://www.dora.lib4ri.ch/wsl/islandora/object/wsl:38186","citation":{"WSL":"Dash R.K., Bartelt P., Zhuang Y., Bühler Y., Kanungo D.P.

Uttarakhand, located in the northwest Indian Himalayas, is one of the most landslide-prone states in India. In a recently published report by the National Remote Sensing Centre (NRSC) India, all the 13 districts of Uttarakhand state are severely affected by landslides and the Chamoli district ranks 3 among 13 districts of Uttarakhand and ranks 19 among 147 landslide-prone districts in the country according to the landslide density (Jain et al. 2023). Over the past three decades, Chamoli has experienced several destructive mass movement events, including the 2013 Kedarnath tragedy, the Chamoli rock and ice avalanche on February 7, 2021, land subsidence in Joshimath during 2023, etc. In 1999, Chamoli was struck by an earthquake with a magnitude of 6.8 on the Richter scale, with its epicenter near Gopeswar township. In addition to landslides and earthquakes, Chamoli has also faced numerous disasters caused by cloudbursts and flash floods. National Highway 58 connects Uttarakhand with the rest of the country, entering Chamoli district through Karnaprayag and extending to Badrinath. This highway passes through the Alakananda Valley, traversing many landslide-prone zones. In a recent study, Ramiz et al. (2023) found that about 27% of the areas along the highway corridor from Rishikesh to Badrinath is highly susceptible to landslides. Frequent landslides, including debris flows, rockfalls, debris slides, and subsidence, disrupt traffic and deposit materials in the river, increasing the likelihood of river damming (Dash et al. 2022, 2023) and traffic disruption. A similar traffic disruption occurred due to a rock avalanche near Patalganga Langsi Tunnel on the Badrinath Highway of Chamoli district on July 10, 2024. This is an area known for frequent rockfall, and debris slide events, as noted by earlier researchers."}]
