Climate change & shipping

In addition to optimising the environmental performance of inland waterway transport, viadonau also considers the challenges of climate change, within the context of international research projects, to be of great importance.  

Climate change could affect the flow regime of the Danube, thereby having a significant effect on the waterway as an infrastructure, flood protection schemes and also the river's ecosystem.

First investigations into the Austrian Danube suggest that, in the medium term, climate change will have a fairly positive impact on inland waterway transport, in particular due to reduced ice formation. Trend analysis relating to to the occurrence of low water, ice formation and reduced visibility show the positive effects of climate change for the period 1950 - 2005. A slight decline is projected until 2050 in terms of the potential for low water events. In the long term, 2050 - 2100, most projections suggest that there may be an increase in possible low-water events.  

Predictions concerning extreme flood events in the context of climate change cannot yet be made with sufficient confidence.  

In the meantime, more climate change projects, involving viadonau, could be carried out to improve knowledge of the effects that climate change may have, specifically on Upper Austria. In general, the level of knowledge about the impact of climate change on the flow regime of the entire Danube and inland waterway transport is still insufficient and more scientifically based research needs to be carried in order to bring more clarity to this issue.

Another specific priority is the consideration of operational and navigational  technical solutions for the reduction of greenhouse gas emissions in inland navigation as a contribution to slowing global warming and the adaptation to changing future fairway conditions.

Supergreen

ECCONET

The ECCONET project examined the impact of climate change on inland navigation in Europe with the emphasis on the Rhine-Main-Danube corridor. For this purpose, the results of existing studies were integrated with newly carried out research to develop new meteorological and hydrological calculations and trend analyses. The study focused on, among other things, ship operations, ship engineering, hydraulic engineering activities and methods for the prediction of water conditions.

EWENT

The EWENT project was launched in 2009 and examined the effects of extreme weather events on transportation systems in the European Union. The aim was to identify risks and consequences for the transport sector and determine the financial consequences. Measures were developed to better manage extreme weather events and recommendations were formulated for decision makers from business, infrastructure management and politics.

 

MOWE IT

MOWE IT was initiated as a result of the EWENT 2012 project. The focus of the project was the identification of "best practices" and the development of appropriate strategies to support transport companies, government agencies and users of the respective transport systems as much as possible. 

The aim was to develop appropriate strategies to reduce the impact of natural disasters and extreme weather events on transport services and infrastructure as much possible. The project was coordinated by the Technical Research Centre of Finland and 12 European research institutes and companies from 8 countries, including viadonau.

The recommendations for the inland navigation sector are summarised in the  “Guidebook for Enhancing Resilience of European Inland Waterway Transport in Extreme Weather Events”.

Supergreen

In Project SUPER GREEN a number of representatives from European transport corridors analysed ways to improve the environmental performance of the European transport system. The selected corridors were subjected to benchmarking, taking environmental aspects, infrastructure parameters, exhaust emissions and also external and internal costs into consideration. Finally, the utilisation of "green" technologies on the selected transport corridors was also analysed.
