Scheduled special issues

The following special issues are scheduled for publication in NHESS:

Flood risk assessment and management
01 Jul 2018–01 Nov 2018 | Guest editors: D. Patel, C. Prieto, D. Han, and K. Schröter | Information

Flooding is the foremost natural hazard around the world, affecting human life and property (directly and indirectly). In the current era, many hydraulic and hydrologic modelling techniques are available for flood risk assessment and management as well as flood risk prevention and preparedness. They provide a platform for the scientific community to explore the causes of floods and to build up efficient methods for flood mitigation.

This special issue invites in-depth research work carried out through flood modelling including hydrological modelling, flood hydrodynamic modelling, flood inundation mapping, flood hazard mapping, risk assessment, flood policy, and flood mitigation strategy. It also welcomes studies dealing with various uncertainties associated with different stages of modelling and the exploration of modern techniques for model calibration and validation.

In addition, real-time flood inundation mapping is an important aspect for the evacuation of people from low-lying areas and reduction of the death toll. Real-time data gained through UAV-based flood inundation mapping and associated uncertainty in real-time aerial surveying are welcome in this special issue.

Advances in computational modelling of natural hazards and geohazards
25 Jun 2018–28 Feb 2019 | Guest editors: A. J. Kettner, G. E. Tucker, R. LeVeque, and N. Kerle | Information

Natural hazards impact thousands of people every year. Floods, droughts, extreme storms, landslides, wildfires, and permafrost erosion all change the Earth's surface and can inflict tremendous damage on human infrastructure. Numerical models of Earth surface processes are one tool to simulate natural hazard processes and provide quantitative pre-event risk assessment. Yet such assessments are only appropriate when the models capture all important physical processes, when the models are tested and well-vetted, when they are usable and proven accurate.

The aim of the special issue is to identify (a) the current state of the art of our current natural hazard process understanding, both fundamentally in the Earth surface processes and in the modelling approaches and technology; (b) important gaps and shortcomings; (c) improvements in natural hazard modelling for risk assessment, with a special focus on building a next-generation cyberinfrastructure and a community of modern modelling and data analysis practices; (d) modeling and conveying uncertainty in numerical risk assessments; and (e) case studies in which numerical models have increased resilience by reducing vulnerability to disasters. This proposal for a NHESS special issue arises from a 3-day international natural hazards conference, Geoprocesses, Geohazards – CSDMS 2018, held during May 22–24th at the University of Colorado, Boulder, USA.

Remote sensing and modelling-based hazard and risk assessment and management of agro-forested ecosystems
01 Jul 2018–31 Jan 2019 | Guest editors: J. Rizzi, A. M. Tarquis, M. Rao, A. Gobin, M. Semenov, W. Zhao, and P. Tarolli | Information

Agricultural and forested areas cover large surfaces over many countries and are a very important resource that needs to be protected and managed correctly for both the environment and the local communities. Food security, population growth, urbanization, and intensive agricultural development are some of the factors that generate increasing demands for water and land resources in the context of global change. Therefore, potential impacts deriving from a changing climate, from more frequent and intense extreme events, and from man-made activities can pose a serious threat to economic infrastructure and development in the coming decades, and also severely undermine food, fodder, water, and energy security for a growing global population.

Significant recent changes in climate and in the hydrological cycle, which is deviating from past trends, will impact on land suitability for agricultural production and on the forest ecosystems. In particular, we can expect an increase in the frequency and intensity of extreme weather and weather-related events such as heat and cold waves, floods, wind and snow storms, droughts, wildfires, tropical storms, and dust storms. Furthermore, man-made activities can exacerbate consequences of an unbalanced environment, such as water quality degradation, groundwater depletion, land subsidence, erosion, and sedimentation. The intensity and frequency of extreme weather and climate events follow trends expected of a warming planet, and more importantly, such events will continue to occur with increased likelihood and severity over large areas of the world. Therefore, sustainable management and exploitation of first-order agricultural resources and forested areas, e.g. available land with favourable climate, soil, and water, will become even more important in the lives and activities of people. This special issue solicits studies allowing quantitative or qualitative assessment of risks based on geospatial technologies such as remote sensing and GIS modelling, including integration of environmental and socio-economical components. Furthermore, the special issue welcomes papers that approach the study of agricultural resources and forest ecosystem management based on technologies and methodologies that have been lately developed.

Hydroclimatic extremes and impacts at catchment to regional scales
23 May 2018–30 Jun 2019 | Guest editors: C. Reason, R. Trigo, S. M. Vicente Serrano, and F. Domínguez-Castro | Information

We invite all hydroclimatic researchers to submit the results of their studies to a special issue of Natural Hazards and Earth System Sciences (NHESS) addressing the theme of hydroclimatic extremes and impacts at catchment to regional scales. Please find the instructions for authors on the NHESS web page. The individual papers will be peer-reviewed and published as soon as they are available in regular issues but will be labelled as part of the special issue and linked electronically.

The main purpose of the special issue is to focus on hydroclimatic extremes (floods and droughts) at catchment and regional scales and their impacts on a broad range of hydrological and environmental systems, including mitigation approaches. Nevertheless, broad topics around hydroclimatic extremes (e.g. temporal variability and trends, atmospheric mechanisms, propagation throughout the hydrological cycle, hydrological modelling of extremes) and the impact of climate change on hydroclimatic extremes are also encouraged.

The special issue was inspired by the Water-JPI IMDROFLOOD project but submissions from all researchers working on suitable topics are welcome, even if they are not participating in the project. In fact, all scientists working on this topic should feel able to contribute. Therefore, please forward this call for papers to your colleagues.

Global- and continental-scale risk assessment for natural hazards: methods and practice
01 May 2018–31 Jan 2019 | Guest editors: Ph. Ward, H. L. Cloke, J. Daniell, M. J. Duncan, and H. Winsemius | Supervising NHESS editor: B. Merz | Information

Reducing natural hazard risk is high on the global political agenda. For example, it is at the heart of the Sendai Framework for Disaster Risk Reduction (and its predecessor the Hyogo Framework for Action) and the Warsaw International Mechanism for Loss and Damage Associated with Climate Change Impacts. In response, the last 5 years have seen an explosion in the number of scientific datasets, methods, and models for assessing risk at the global and continental scale. More and more, these datasets, methods, and models are being applied together with stakeholders in the decision-making process.

The purpose of the special issue is to (1) provide a high-quality collection of papers showcasing the current state of the art of global- and continental-scale natural hazard risk assessment and application; (2) foster broader exchange of knowledge, datasets, methods, models, and good practice between scientists and practitioners working on different natural hazards and across disciplines globally; and (3) collaboratively identify future research avenues.

We invite contributions related to all aspects of natural hazard risk assessment at the continental to global scale, including contributions focusing on single hazards, multiple hazards, or a combination or cascade of hazards. We also encourage contributions examining the use of scientific methods in practice and the appropriate use of continental to global risk assessment data in efforts to reduce risks. Furthermore, we encourage contributions focusing on globally applicable methods, such as novel methods for using globally available datasets and models to force more local models or inform more local risk assessment.

Hydrological cycle in the Mediterranean (ACP/AMT/GMD/HESS/NHESS/OS inter-journal SI)
01 Apr 2018–31 Dec 2021 | Guest editors: G. T. Aronica, C. Barthlott, D. Cimini, E. Martin, M. Meier, R. Moussa, K. Schroeder, H. Wernli, and V. Ducrocq | Supervising NHESS editor: V. Kotroni | Information

The Hydrological cycle in the Mediterranean Experiment (HyMeX, programme is a 10-year concerted effort at the international level started in 2010 with aims to advance the understanding of the water cycle, and with emphases on the predictability and evolution of high-impact weather events, as well as on evaluating social vulnerability to these extreme events. The special issue is jointly organized between the Atmospheric Chemistry and Physics, Hydrology and Earth System Sciences, Ocean Science, Natural Hazards and Earth System Sciences, Atmospheric Measurement Techniques, and Geoscientific Model Development journals. It aims at gathering contributions to the areas of understanding, modelling, and predicting at various timescales and spatial scales of the Mediterranean water cycle and its related extreme events, including cyclones, heavy precipitation, flash floods and impacts, drought and water resources, strong winds, and dense water formation. The special issue is not limited to studies conducted within HyMeX: any multiscale or multidisciplinary approaches related to the Mediterranean water cycle are encouraged.

Spatial and temporal patterns of wildfires: models, theory, and reality 31 Aug 2017–31 Dec 2018 | Guest editors: M. G. Pereira, R. Trigo, M. Tonini, and N. Koutsias | Supervising NHESS editor: R. Trigo | Information

Wildfires are the result of a large variety of interacting natural and anthropogenic components, which produce patterns that vary significantly both in space and in time.

In this context, this special issue will examine models, theory, empirical studies, new and innovative technologies for wildfire research and cover the various stages of the fire from the preview of occurrence through to detection, variability, modelling, and consequences; however, the focus will be on the spatial and temporal patterns of fires. Thus, the main purpose of this special issue will be the spatial and temporal distribution as well as the drivers of various aspects of the fire regime. Nevertheless, broad topics around wildfires (e.g. detection/remote sensing application, modelling, risk zones, burned area, and land-use-related covers) and the impact of climate change on wildfires are also encouraged.

Research topics include but are not limited to

  • fire detection and monitoring, including remote sensing and innovative technologies for wildfire detection;
  • fire spread models, ranging from case studies to long-term climatological assessments;
  • pre-fire planning, risk assessment, and management;
  • post-fire assessment, such as burned area mapping, fire severity, and damage (vegetation’s composition, decrease in forests, loss of biodiversity, soil degradation, alteration of landscape patterns and ecosystem functioning);
  • post-fire vegetation recovery, including time series satellite data and vegetation phenology;
  • influence of weather and climate/climate change on wildfire activity;
  • fire impacts on the environment, in particular on the atmosphere and human health;
  • relationship between wildfires and social and economic drivers and changes.


Environmental changes and hazards in the Dead Sea region (NHESS/ACP/HESS/SE inter-journal SI) 26 Jun 2017–30 Sep 2018 | Guest editors: S. Parolai, S. Geyer, and O. Katz | Information

The Dead Sea region constitutes a unique environmental system on Earth. Set in an extraordinary landscape and cultural area, it is central to life in this region and of great economic and ecological importance. Today, the region is faced with rapid environmental changes and a multitude of hazardous natural phenomena. The ongoing lake level decline of the Dead Sea, the desertification process, occasional flash floods, the development of numerous sinkholes, and the existing significant seismic risk indicate that the region can by affected by important human, economic, and ecologic loss in future. Due to its outstanding characteristics, such as sharp climatic gradients, extreme water salinity, its dynamics, and the combination of both natural and anthropogenic drivers, the Dead Sea region represents a unique natural laboratory in which to study multiple disciplines such as geophysics, hydrology, and meteorology.

The environmental changes in Earth, atmosphere, and water are linked to the main geomorphic feature in the region, the Dead Sea Transform fault system. Due to this active fault zone, the region is exposed to severe earthquake hazard, which in turn, considering the exposed assets and the vulnerability of the building stock, determines a significant seismic risk in the region. Knowledge about processes and structures in the underground is also required for the study of sinkholes. Sinkholes form when groundwater, undersaturated with respect to easily soluble minerals, uses faults as conduits to percolate to subsurface salt deposits. The water dissolves and flushes the salt, leading to a collapse of the underground substrate structure. Thus, the development of sinkholes is enabled. Besides triggering sinkhole formation, groundwater recharge determines the available water resources. The Dead Sea being a terminal lake, its water level decline is controlled by changes in subsurface as well as surface water inflow and evaporation. A direct link to hydrology and atmospheric sciences is thereby established. The rapid shrinking of the water surface area is accompanied by a strong local climatic change, which induces changes in atmospheric circulation patterns. Here, the Dead Sea can be viewed as a laboratory for studying effects of climate change under much accelerated conditions compared to the rest of the world.

The objective of the multidisciplinary special issue "Environmental changes and hazards in the Dead Sea region" is to compile research and recent advances on the atmospheric, hydrological, and geophysical processes and dynamics of the Dead Sea and its surroundings, which are also of prototype relevance for other (semi)arid terminal basins of the world. Papers included in this special issue could address the processes of sinkhole genesis, groundwater recharge and movement, flash flooding, as well as seismic or severe meteorological events and could include topics such as the quantification of the water budget components. Moreover, contributions are invited that demonstrate how this knowledge contributes to aspects of risk assessment (or its main components like hazard, exposure, and vulnerability) and could assist in efficient risk mitigation and remediation strategies as well as to appropriate implementation of early warning systems in the region. Both measurement and modelling studies are welcome.

The planned special issue aims to address the unique conditions of the Dead Sea region from different disciplinary views. Given the fast environmental changes in the different spheres, the special issue will be of wide interest to readers from seismologists, geophysicists, engineers, and hydrologists to meteorologists. Interest will not be limited to researchers working in the region as similar changes are occurring in other parts of the world too, many on a much longer timescale.

The special issue is initiated by the Helmholtz Virtual Institute’s DEad SEa Research VEnue (DESERVE). The project brings together researchers working on diverse research fields related to the Dead Sea environment. The special issue will be open for all submissions within its scope.
