Landslide early warning systems: monitoring systems, rainfall thresholds, warning models, performance evaluation and risk perception
13 Mar 2017–30 Jun 2017 | Guest editors: S. Segoni, L. Piciullo, S. L. Gariano, T. A. Bogaard, and F. Catani | Information
This special issue focuses on landslide early warning systems (LEWSs) at both regional and local scale, with specific reference to landslides induced by rainfall and/or snowmelt. LEWSs at regional scale are used to assess the probability of landslide occurrence over a priori-defined warning zones, typically through forecasting and monitoring of meteorological variables, in order to give generalized warnings to communities and institutions working with hazard mitigation measures. Conversely, the main aim of LEWSs at a local scale is the temporary evacuation of people from areas where, at specific times, the risk level to which they are exposed can become intolerably high. The structure of LEWSs can be schematized as an interrelation of both technical and social components. The definition of these components and the aims of the alert issued may vary as a function of the scale at which the system is employed.
The special issue wishes to highlight approaches and developments regarding correlation laws, monitoring systems, models for issuing different warning levels, landslide and warning databases, landslide forecasting, weather prediction models, emergency phases, communication strategies, performance analysis of the warnings issued, and other activities necessary for designing and operating LEWSs.
We expect contributions addressing the following topics:
The special issue will be open to every submission within its scope.
Landslide–road network interactions
26 Oct 2016–31 Jul 2017 | Guest editors: P. Tarolli, F. E. Taylor, and B. D. Malamud | Information
When landslides occur on or near a road, they have the potential to cause road blockages, delays, detours, damage and closures, resulting in economic and societal impacts. Roads may increase landslide susceptibility (e.g. through over-steepening) or decrease susceptibility (e.g. through drainage routing, or strengthening of the soil), resulting in a complex interplay between transport lines, susceptibility, landslides and people. This special issue welcomes papers on landslide–road interactions on themes such as spatial and numerical modelling, physical process, landslide susceptibility, potential and actual impact, risk assessments, and novel early-warning systems. We particularly welcome papers with novel conclusions or broad implications for the management of landslide–road interactions. Authors are discouraged from submitting solely engineering papers that do not also deal with process or broader landslide–road interplay issues. If you are unsure of suitability, please write the guest editors before submission to the special issue. We encourage authors to include either links to or actual supplementary material to share model code, data, videos, etc.
The use of remotely piloted aircraft systems (RPAS) in monitoring applications and management of natural hazards
20 Jul 2016–01 Jun 2017 | Guest editors: D. Giordan, Y. S. Hayakawa, F. Nex | Supervising NHESS editor: P. Tarolli | Information
The use of remotely piloted aircraft systems (RPAS) for civil applications is a new perspective in the field of natural hazard phenomena. The amazing diffusion of mini- and micro-RPAS is becoming a valuable alternative to the traditional monitoring and surveying applications, opening new interesting viewpoints. The acquisition of high-resolution remotely sensed data from RPAS in areas characterized by hazardous natural processes can be a powerful instrument to quickly assess the damages and to plan effective rescues without any risk for operators. The main goal of these systems is the collection of different data (e.g. images, gas or radioactivity concentrations, etc.) and the delivery of various products (e.g. 3-D models, hazard maps, high-resolution ortho-images, etc.). The high repeatability of RPAS flights and their limited costs also allows for a multi-temporal analysis of an area. However, methodologies, best practices, advantages, and limitations of these kinds of applications are unclear and/or poorly shared by the scientific community. This special issue aims at exploring the open research issues and possible applications of RPAS in the field of monitoring and management of geo-hazards to collect experiences, case studies, and results, as well as to define methodologies and best practices for their effective use in geo-hazard contexts such as landslides, floods, earthquakes, and volcanic areas. Papers dealing with the integration of heterogeneous sensors (gas sensor, multi-spectral and thermal images, lidar, vision-based navigation systems, etc.) for innovative applications in the geo-hazard domain will be particularly encouraged.
Damage of natural hazards: assessment and mitigation
10 May 2016–31 May 2017 | Guest editors: M. H. Spekkers, T. Glade, D. Molinari, T. Thaler, M.-C. Veldhuis, and H. Kreibich | Supervising NHESS editor: H. Kreibich | Information
Analysis and modelling of damage due to natural hazards supply crucial information for decision-making in risk management and climate-change adaptation. However, a lack of data (particularly damage data but also information about costs of risk mitigation) as well as the significant diversity in methods that are currently applied in damage assessments of different natural hazards and impacted sectors make it difficult to establish comprehensive, robust, and reliable cost figures. Thus, comparisons of associated costs across countries, hazards, and impacted sectors are a challenge.
This special issue will present current methodological approaches for assessing individual cost types (such as direct damage to housing, indirect losses, as well as costs of risk reduction) and aims to show how these methods are used for the management of various natural hazards (e.g. floods, droughts, alpine hazards, coastal hazards). We will include papers on the assessment of these various types of damage, for any kind of natural hazards. Also, we are interested in contributions that focus on the cost effectiveness or efficiency of risk-reduction measures. Papers are welcome on model development, validation, uncertainty analysis, risk-assessment frameworks, applications of damage models in case studies, as well as about the evaluation of risk mitigation measures.
The special issue shall be open for all submissions within the scope of the special issue. However, many papers may be inspired by the EGU 2015 and 2016 Sessions NH9.2 Costs of Natural Hazards organized by the proposed guest editors.
