Debris flow warning system (SALT)

Real-time operational warning system for debris flow forecasting in Valais The aim of the Système d’Alerte de Laves Torrentielles (SALT) project is to set up a meteorological warning system for selected sites throughout the canton of Valais. These areas have been affected by numerous debris flow events in the past, which is why a real-time warning system project has been initiated to prevent such events in the future. This system enables SMS… Read More
Randa rockfall (1991)

The data collected on this site has been an essential source of knowledge for analyzing the behavior of the Grossgufer massif and managing the associated risks. Preamble In the spring of 1991, the village of Randa in the Mattertal valley, some 5 km downstream of Zermatt, was the scene of one of the largest rockfalls in Europe in the 20th century, along with that of Val Pola (Valtelline, Italy, 1987). In all,… Read More
Matterock methodology

A methodology for monitoring cliffs and detecting potential major landslides The major rockfall at Randa (Valais, Switzerland) in the spring of 1991 (30 Mom3) highlighted the scientific shortcomings in predicting such catastrophic events. It was therefore decided to develop a cliff monitoring methodology that would provide a better understanding of the phenomenon of cliff instability and anticipate potential rockfalls. This methodology, called MATTEROCK, was developed as part of the National Research Program… Read More
Geocadastre | geological surveys

Le cadastre cantonal des sondages géologiques – a web portal for consulting and editing subsoil data for the Canton of Valais Launched at the end of 2013, Géocadastre – the cantonal geological survey cadastre – has gradually established itself as a reference tool for practitioners. The Geocadast web portal not only enables consultation of subsurface data, but also provides information on the cantonal cadastre. The quaternary data contained in the Geocadastre are… Read More
Charriage + seismic sensors

SismoRiv project: Development of a charriage measurement system based on low-cost seismic sensors The aim of this project, which is dedicated to the issue of sediment transport, is to develop a measurement method that is simple to install and use, effective and considerably less costly for the various players involved (developers, risk managers, cantonal and municipal services). The monitoring of solid transport by watercourses is indeed of great economic and ecological importance…. Read More
Spatial Reference Information System | Floods

A Spatially Referenced Information System for managing hydrological hazards in the canton of Valais SIRS-CRUES is one of a series of spatially referenced information systems (SIRS) set up by the canton of Valais to optimize the use and enhancement of information contained in natural hazard studies (avalanches, floods, ground instabilities). SIRS-CRUES records information relating to hydrological hazards. Developed on the initiative of the Natural Hazards Service(SDANA) and with the collaboration of the… Read More
RS MINERVE software

Modeling hydrological and hydraulic networks using a semi-distributed approach PRESENTATION RS MINERVE is a hydrological and hydraulic modeling software package that simulates rainfall-runoff transformations and free-surface flows. The software is capable of representing not only the main hydrological processes such as snowmelt, glacial melt and surface and subsurface flows, but also regulated structures such as reservoirs, gates, spillways, water intakes, turbines or pumps, and other hydraulic structures. Comprehensive analysis of a hydrological-hydraulic… Read More
Spatial Reference Information System | Geological Hazards

A Spatially Referenced Information System for managing geological hazards in the canton of Valais SIRS-DAGEO is one of the spatially referenced information systems (SIRS) set up by the canton of Valais to optimize the use and development of information contained in natural hazard studies (avalanches, floods, ground instabilities). SIRS-DAGEO records information relating to geological hazards. Launched by the canton of Valais in 2004, SIRS-DAGEO enables data from geological hazard studies to be… Read More
Hydrometric network monitoring

Hydrometric network of the Canton of Valais Hydrometric monitoring of lateral watercourses on a cantonal scale has two main objectives: The hydrometric network, commissioned at the end of 2015, comprises some twenty stations. It is managed and maintained by CREALP with technical collaboration from the“Maintenance Logistics” section of the Mobility Service(SDM).
