In contrast to global climate model projections the intensity of summer rainfall may increase. This is important for fresh water supply and, for instance, with respect to flash floods.

For the Alps, the main trigger of debris flows is high intensity, short duration rainfall. Under future climate change, it is likely that increases in extreme rainfall will alter debris flow frequency

Numerous concepts have been developed to mitigate the heat load in urban areas, such as customizing urban vegetation for shading and evaporative cooling, introducing open water

Global warming affects precipitation volumes in the Alps, the contribution of rain and snow to these volumes, and the timing of snowmelt. An overall decrease in snow cover

Climate change is considered a large threat to especially montane species. These species often inhabit narrow elevational ranges

There is growing evidence that the rate of warming is amplified with elevation, such that high-mountain environments experience more rapid changes in temperature

For Norway spruce in the Northern Limestone Alps (Germany and Austria), neither growth suppression at the lower elevation sites nor growth increase at higher elevation sites was observed

In the past decade, winter consequences and flood events accounted for 96% of the total rail and road networks costs in the Alps, 92% in mid-Europe and 91% across EUR29.

On the Rhine–Main–Danube corridor no decrease in the performance of inland waterway transport due to extreme weather events is expected till 2050.

In the Alps, the overall frequency of debris flows may decrease in absolute terms, but the magnitude of events may increase.

Strong reduction of snow cover in the Alps is expected to have major impacts on winter tourism. Many ski-regions have mean elevations below 2,000 m

Alpine countries suffered from economic losses of € 57 billion caused by natural hazards—only in the period from 1982 to 2005. The extensive flood in the Alpine region in August 2005

So far, forest fires do not constitute a significant hazard in the central and northern parts of the Alps, while on the southern side they are more common

Vulnerabilities - Flood risk landfill sites

Maintenance and decomposition for landfill life cycles are assessed for 200–500 years depending on waste composition, climatic conditions and applied assessment methodologies (1). Consequently, even sites with flood protection levels up to a 100-year flood, for example provided by dykes, are highly likely to be inundated before hazardous materials are decomposed. It has to be assumed that inundated landfills become water-saturated, which leads to a substantial mobilisation of pollutants, as the presence of water enhances decomposition and transport processes (2). In addition, water saturation of landfills may lead to mechanical stability losses (3). As landfill sites are predominately located in lowland areas close to residential areas, a permanent risk potential for humans (adverse health effects) and the environment has to be expected resulting from flooded landfills (4).

Potential effects of landfill flooding have been assessed for Austrian landfills mainly composed of municipal solid waste (5). An inventory of landfills in Austria showed 103 sites characterised as controlled landfills and 961 sites identified as uncontrolled landfills with overall volumes of more than 25,000 m3 (6).


One-third of the controlled landfill sites and roughly 30 % of the uncontrolled landfills were identified as highly endangered by floods (landfill located within a flood risk zone or at less than 150 m distance from the flood risk zone, for floods with return periods of 200 years). The majority (60 %) of active controlled landfills are protected by structural measures (e.g. dykes) (in flood-prone areas usually against 100-year flood events); the majority (70 %) of closed controlled sites are unprotected (5). This information is not available for uncontrolled landfills; in general, it is assumed that these sites are not protected at all (7).

The results demonstrated that the load of pollutants from flooded landfills can potentially increase by up to six orders of magnitude, depending on the substance and the underlying assumption of the scenarios. Therefore, the flow of substances from flooded landfills to the environment is significantly high with a corresponding risk. Despite the high dilution potential during a flood event, discharges to rivers are highly likely to exceed the Austrian Water Quality Standards. Inherent uncertainties associated with considered processes and data sources are considerably high, however (5).

In many cases landfills endangered by flooding might be inundated but not eroded during a flood event. The subsequent water saturation of a landfill body can have significant impact on post-flooding landfill metabolism and might be of interest from the perspective of landfill aftercare (5).
