Rivers flow through aeolian dunes and always adopt braided stream channels in response to aeolian and fluvial sediment supplies. Here our results indicate that these braided rivers are distinguished from coarser-grained thalweg beds and finer-grained bar or floodplain surfaces and develop a significant lateral selective deposition in bed sediment. The traditional downstream fining shows no significance in this braided channel, primarily due to aeolian sand supplies.

Due to the severe hazardous processes many lives have been lost in the area: at least 250 deaths have been recorded since the 18th century, accounting for 36 different dates/events. Many research topics remain to be developed, especially those concerning (a) the time period during which natural events of a given intensity may recur, and (b) the improvement of techniques and knowledge, at the highest possible detail and in relation to anthropogenic activities.

We used InSAR to measure the Var delta subsidence (with a 1-σ error of 0.25 mm/yr, what might be the best documented delta deformation) that includes the NCA airport platform, located on reclaimed lands. We found that subsidence affects that whole delta and is primarily caused by the compaction of the delta quaternary sedimentary wedge. On the NCA platform, the subsidence rate reaches up to 10 mm/yr and represents a serious threat as it overlooks the steep submarine slopes of the shelf break.

We present a spatiotemporal picture of winter backcountry usage in the Swiss Alps and compare this with the distribution of avalanche accidents. Critical avalanche danger conditions and an unfavorable snowpack (old snow problem) strongly increase the risk of winter backcountry recreationists to be involved in a severe avalanche accident. This explains why there are comparably more accidents in the inneralpine regions with less activity.

In this study, a response system is set up at harbors against unexpected tsunami attacks. The response system may contribute to mitigate natural disasters and provide guidelines for future disaster prevention researches.

Straightforward communication of monitoring results is of major importance in emergency scenarios relevant to large slope instabilities. Here we describe the communication strategy developed for the Mont de La Saxe case study, a large rockslide threatening La Palud and Entrèves hamlets in the Courmayeur municipality (Aosta Valley, Italy).

A distribution-based scaling approach was developed and proven useful as a post-process to correct systematic biases in climate modelling outputs (i.e. precipitation, temperature, relative humidity and wind speed) to facilitate the utilisation of climate projections in forest fire risk studies. The result showed reduction of bias in forcing data and an improved description of fire-risk-related indices. Concerning the future climate, southern Sweden is likely to become a more fire-prone region.

The current paper intends to identify the impact of low-light conditions on traffic accidents in an urban area. Knowing the linear dependence and the spatial relation between the low light and the number of traffic accidents, as well as the consequences of their occurrence, enabled us to identify the areas of high road traffic accident risk.

The work presented represents a quantitative assessment of the impact of clay-related subsidence on the local road network of Lincolnshire, UK. It provides a methodology into how Lincolnshire County Council have used soil-related geohazard maps as a soil-informed maintenance strategy for maintaining their highway network. The research presented represents a component within the current UK Infrastructure Transitions Research Consortium (ITRC) http://www.itrc.org.uk/.

The aim of this paper is to provide a useful approach for the evaluation of shallow landslide-triggering scenarios through numerical modeling. Since the numerical models are, in general, exceptionally demanding in terms of parameterization, and the required information often exceeds available data, this approach combines different methods for the definition of the input parameters of the model in such a way that it is applicable to different case studies, on the basis of the data availability.

In this work, we present a new semi-automatic procedure to prepare landslide inventory maps that uses GIS applications and tools for the digitization of photo-interpreted data. Results show that the new semi-automatic procedure proves more efficient for the production of landslide inventories and results in the production of more accurate maps, compared to the manual procedure. The presented work has potential consequences for multiple applications of landslide studies.

A spatially explicit object-based temporal assessment of buildings and citizens exposed to natural hazards in Austria is presented, including elements at risk of river flooding, torrential flooding, and snow avalanches. It is shown that the repeatedly stated assumption of increasing losses due to continued population growth and related increase in assets has to be opposed to the local development of building stock, which is spatially and temporally variable.

This paper presents a study of extremely hot days (EHDs) in Spain and their connection with atmospheric dynamics. In addition, this work proposes a method that allows the detection of trends in the frequency of extreme events and their attribution to changes in atmospheric dynamics characterized through circulation types (CTs). The main CT-driven EHDs are identified. The increase in the EHD appearance is linked to the increase of the extreme CTs; however this only partially explains the trends.

This study applied the two-dimensional AdH (adaptive hydraulics) hydrodynamic model to a river reach to analyze flood hydraulics on complex floodplains. A detailed analysis of the floodwater dynamics was conducted using the modeling approach to examine the hydraulic linkage between the main channel and floodplains.
