Call for abstracts : JTC1 Workshop on Impact of global changes on landslide risk (7-10 June, 2023)

NEWS received from
Vittoria Capobianco – NGI, Norway

The Joint Technical Committee on Natural Slopes and Landslides (JTC1) of FedICGS is delighted to invite you to join us at the 3rd JTC1 Workshop on Impact of global changes on landslide risk, to be held in Oslo, Norway on June 7th – 10th, 2023.

3rd JTC1 Workshop on Impact of global changes on landslide risk

Anthropogenic impacts and related climate change are unquestionably changing the landslide risk and impacting how we assess and manage the risk(s).

The aim of the Workshop is to promote discussion between scientists and engineers on whether we are capable of predicting and quantifying the expected changes in landslide risk and how we could implement the knowledge gained from academic research on landslide risk management into practice. The advanced topics in focus for the discussions include:

  • Rock mass degradation and landslide initiation;
  • Climate and anthropogenic impact on landslide risk in various geographic regions, including the Arctic;
  • Prediction of landslide mobility and impact footprint, including landslides initiated at mine tailings storage facilities;
  • Application of modern remote sensing technologies to landslide risk assessment; 
  • Landslide risk reduction strategies: risk mitigation, including early warning and nature-based solutions;
  • Applications of new technologies like machine learning for landslide susceptibility and landslide hazard mapping.

The workshop will consist of two lecture days (June 8 and 9), and a one-day technical excursion (June 10). The lecture days will be a combination of five keynote lectures, a number of invited lectures, the 3rd Hutchinson Lecture as well as discussion sessions.

You are invited to submit extended abstracts (up to 4 pages) for oral presentation and short abstracts (max 1 page) for poster presentation. Instructions and templates for abstract submission can be found here.

The deadline for submitting both extended and poster abstracts is 31 March 2022.

The digital proceedings will be issued right after the workshop and made available on the 3rd JTC1 Workshop website.

The Organizing Committee will make a selection of the best abstracts (oral presentations and posters) and invite the authors to provide a full manuscript to be published in a Special Issue of a refereed, open-access journal. A total of 10 to 15 articles are envisioned for the Special Issue, which is expected to be published within one year after the workshop.

For detailed information check the dedicated website at: https://jtc1-2023.com/

Looking forward to seeing you in Oslo, 2023!

Seven years of landslide forecasting in Norway. Strengths and limitations

NEWS received from
Graziella Devoli – NVE, Norway

New conference proceedings “Seven years of landslide forecasting in Norway – Strengths and limitations”  presented at 5th World landslide Forum, Kyoto, Japan (WLF5 | World Lanslide Forum 5 (iplhq.org))

In this short paper, the authors summarize the experiences acquired by the Norwegian Landslide Forecasting and Warning Service during the first 7 years (between 2013 and 2019) of operation and discuss some of the main strengths and limitations of the service. The authors recognize that the major strengths of the service were the national political will (towards the creation of such of service), the assignation of the landslide forecasting service to an existing well consolidated flood warning service, the strong collaboration across public agencies and the multidisciplinary approach. The existence of a national landslide database and of an operational distributed hydrological model were essential for the rapid establishment of relationships between landslides events and hydro-meteorological conditions. A strong development of IT-tools and expansion of the meteorological and hydrological network was also crucial. Several are the challenges and limitations, among them: an insufficient process-understanding of rainfall- and snowmelt-induced landslides, the difficult and tedious task of verifying landslide occurrence after a warning is sent and, the prediction of landslides triggered by local intense rain showers during summer, and by rapid snowmelt events during winter, due to the limitations that exist in the models and thresholds currently in use.

New article on wildfire effects on debris flows and LEWS

NEWS received from
Davide Tiranti, Regional Agency for Environmental Protection of Piedmont region, Italy

New article “Wildfires Effect on Debris Flow Occurrence in Italian Western Alps: Preliminary Considerations to Refine Debris Flow Early Warnings System Criteria” published in the special issue of Geosciences journal on “Local and Territorial Landslide Early Warning Systems

In this paper, two case studies in the Italian western Alps on the relationship between wildfires and debris flows occurrence have been analyzed to understand how to integrate this factor in the regional debris flow early warning system (DFEWS). To define these correlations, the authors conducted analyses to characterize changes in the conditions and behavior of catchments after wildfires. The Curve Number (CN) method was adopted to estimate hydrological variations before and after wildfires and identify the differences in catchments response to rainfall events, due to its simple applicability over a large number of catchments. Rainfall analyses, using both data from raingauges and weather radars to identify the actual distribution of precipitation intensity fields, were addressed. The case studies described have led to some interesting results, both regarding the understanding of the wildfires effects on debris flows triggering in small Alpine catchments and on the necessary technical and operational adjustments to improve the DFEWS performance in case of wildfire occurrence.

New article: Landslide risk assessment considering socionatural factors

NEWS received from
Paulo Hader – São Paulo State University (UNESP)

New article: Risk cross-referencing for landslide risk assessment at a municipal scale, by Paulo Hader and co-authors from São Paulo State University, Brazil

This recently published paper proposes a model for landslide risk assessment at the municipal scale, useful for early waninrg purposes.
Three products, being rainfall thresholds, landslide susceptibility map and social vulnerability map were produced statistically. To couple them, the authors used a two-matrix approach, where in the first matrix the susceptibility map and the vulnerability map were crossed, constituting the socio-natural criterion; and in the second matrix, the rainfall thresholds were coupled to the socionatural criterion, allowing a real-time assessment.
The authors found that the model offers easy adaptation and calibration once new data emerges, as well as being able to be integrated into a landslide early warning system to make explicit the areas of highest degree of loss, where interventions can be made in advance to reduce the risk in specific areas.

New article: Wicki et al. (2021)

In a recently published article we assess the potential of simulated soil moisture for regional landslide early warning. For this study, soil moisture variation was simulated with a physically-based 1D soil water transfer model and forecasst goodness for landslides was assessed using a statistical landslide forecast model. In direct comparison with in-situ measured soil moisture we found that the overall representativeness for regional landslide occurence is high, however that it is particularly challenging to well characterize critical antecedent wetness conditions.
