Session on LEWS at EGU2022

NEWS received from
Luca Piciullo, Dalia Kirschbaum, Neelima Satyam, Samuele Segoni, and Stefano Luigi Gariano

The EGU General Assembly 2022 #EGU22 will return as an in-person/hybrid event to Vienna, Austria, from 3-8 April 2022, once again bringing together geoscientists from all over the world.
The session entitled “Towards reliable Landslide Early Warning Systems” is now open to receive your contributions.

The session focuses on LEWSs at both regional and local scales. The session wishes to highlight operational approaches, original achievements and developments useful to operate reliable (efficient and effective) local and territorial LEWSs.
Contributions addressing the following topics are welcome:
rainfall thresholds definition for warning purposes;
–  monitoring systems for early warning purposes;
warning models for warning levels issuing;
performance analysis of landslide warning models;
communication strategies;
emergency phase management.

More info at https://meetingorganizer.copernicus.org/EGU22/session/43376

The deadline for abstract submission is 12 January 2022, 13:00 CET.

For those applying for EGU Roland Schlich travel support, the deadline is 1 December 2021, 13:00 CET. Only EGU members with a valid 2022 membership will be able to submit abstracts to EGU22 and, with a few exceptions, only one abstract as first author will be permitted.

Note on presentation format: if you plan on participating virtually, you should submit your abstract to a vPICO session, since the oral/poster sessions will not provide the possibility for virtual presentation. If you plan on attending in-person in Vienna, feel free to submit to any session, vPICO as well as oral/poster sessions.

Looking forward to receiving your contributions and to meeting you all (in person or virtually) soon!

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 SHEAR publications introducing LEWS

NEWS received from
Mirianna Budimir, Practical Action, SHEAR Knowledge Broker

The Science for Humanitarian Emergencies and Resilience (SHEAR) programme funded by FCDO and UKRI NERC supports world-leading research to enhance the quality, availability and use of risk and forecast information.

SHEAR is delighted to share with you three complementary resources that bring together learning and knowledge from across SHEAR and published literature to provide an introduction to landslide early warning systems for practitioners, donors, and researchers in developing countries:

We hope these introductory guides are useful for the LandAware community. For further information on the SHEAR programme and associated landslide projects and publications, please visit http://shear.org.uk.

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.
