Selected Projects

viadonau is Europe's leading force in the field of near-natural river engineering and innovative water protection for waterways.  

The implementation of countless projects has led to the expansion of our expertise in environmental water conservancy and we therefore possess the necessary experience to improve ecological conditions.

FGP

In order to enhance fairway conditions to the east of Vienna, an extensive integrative project was developed - the "Integrated River Engineering Project on the Danube East of Vienna (FGP)".

The main objective of this project is to provide a long-term solution to the erosion of the riverbed along the stretch of the Danube between the Freudenau power plant and the Austrian-Slovakian border. Extensive measures have been implemented to restore and ensure reliable fairway conditions for navigation along this stretch of the river.

During the integrative planning process of a project, interdisciplinarity is the number one priority. Experts in hydraulic engineering, shipping and ecology worked together as partners for many years to find an optimal solution for the Danube east of Vienna.

LIFE NATUR Wachau

Side arm system Grimsing 2013, ©viadonau

One of the key objectives of the LIFE Nature project is the structuring of the Danube’s main current. Using the “LIFE Wachau gravel concept” as a basis, gravel dredged by viadonau from the shipping fairway is used to create banks and islands near to the shore. Nearly 427,000 m³ of gravel has been used in this way to construct 24 different structures, thereby enabling gravel dredged from the Wachau section of the river to remain in the Wachau. The backwaters of Grimsing, Aggsbach Dorf and Rührsdorf-Rossatz were all reconnected to the Danube. The purpose of reconnecting these side arms to the Danube again was to ensure the long-term year-round flow of the Danube’s waters and this has now been successfully implemented.

LIFE + Mostviertel Wachau

The LIFE + project Mostviertel - Wachau implemented measures to improve the river habitats at two Natura 2000 sites (Natura 2000 area "Wachau" and "Wachau - Jauerling" as well as the "the rivers in the alpine foothills of Lower Austria" and "Pielachtal").  

Measures were put into effect to promote the wellbeing of all types of fish in the Danube, where a majority of the 57 native fish species are on the IUCN Red List of Threatened Species. The project consequently also contributes to biodiversity, conservation and an improvement to ecological integrity in accordance with the EU Water Framework Directive.

LIFE + Auenwildnis Wachau

The project "Auenwildnis Wachau" combines the two previous LIFE projects in the Wachau region, and is based on their collective experiences. Extensive measures for the revitalisation of the remaining side arms are planned for the period from 2015 to 2020.  Existing riparian areas on existing and emerging Islands will be improved and expanded as part of this project.

LIFE + Renaturierung Untere March-Auen

Markthofer tributary, ©Steiner

The March is the largest left bank feeder river in the upper reaches of the Danube and the only natural lowland river with Pannonian characteristics in Austria. Due to regulatory and intensification measures implemented in the last century, the river is no longer in an optimal condition. The EU-funded project "Restoration Lower March-Auen" began in 2011 and involves the implementation of numerous ambitious restoration measures and conservation projects. The aim of the project is the restoration of near-natural river dynamics in the Lower March wetlands and to ensure extensive cultivation as well as targeted measures for the protection of endangered species.
