Project summary
The sediment transport monitoring made in this project was the first monitoring of this kind in Austria and was as successful as it was expected to be.
“At the border section of the Mur River between Austria and Slovenia, systematic river training and hydroelectric power plants have led to a channel incision with considerable ecological and technical consequences. A sediment transport model predicted further incision if no countermeasures are implemented. The thin gravel layer (≈0.5 m) poses the threat of a river-bed break-through, calling for urgent action. In a Basic Water Management Concept, several types of ecologically oriented countermeasures have been proposed. Recently, one measure that combines self-initiated riverbank erosion with sediment input from a newly constructed side-arm has been implemented. To determine the success of the measure, we conducted a detailed survey along with particle tracking by telemetry. The results show the anticipated response. So far the Mur River showed the intended response to the measures with respect to self-initiated bank erosion and distribution of the inserted gravel. The introduced monitoring program proved to be suitable for the assessment of the measures.”

To identify the major impairments for the ecological status of waters and aquatic habitats at Drava and Mur, a scientific monitoring of habitats and species was carried out. Particular attention was paid to the wolf spider Arctosa cinerea, the beetle species Cicindela hybrida, and the bird species Actitis hypoleucos and Charadrius dubius. In the area of Bad Radkersburg, Drauchenbach up to the border a fish-ecological evaluation has been conducted at the river Mur. In the area of the measure Gosdorf I, an Interreg IIIa (2002-2008) project, a detailed monitoring and habitat modeling as well as an investigation of habitat types and species, visitor pressure and neophytes was done. The pre-and post-monitoring-results show a remarkable development of existing and new habitats of the studied protected resources. The dynamic river engineering projects have significantly promoted the development of all habitats concerned and a substantial improvement of habitats and animals has been documented.
