Project summary

Edit project overview to modify the project summary.

In the Weyern-Au space for the development of natural river habitats has been created over a length of about 1.2 km. This has been facilitated by the creation of two side-arms. The islands between the tributaries and the river Mur are unsecured, so the river Mur can form natural waters and shoreline structures. In the hinterland alluvial basins were created as amphibian breeding waters with large areas of shallow water. One abandoned meander which is connected only downriver to this new side-arm serves as valuable winter rest and refuge for fish. Through the release of 4 ha land natural alluvial forest will develop instead of the existing spruce forests. In addition, the water accessibility for the population has been improved.

GerambRose 2010: The measure river widening Weyern of the project Murerleben 2003-2007 was awarded on 17.09.2010 with the GerambRose. The GerambRose is awarded in Styria in appreciation for services that maintain or create high-quality architecture. Neither the owner, the designer nor the performers, but their collective effort, the building, is the focus point of the price. The theme of the GerambRose 2010 was dedicated to the "public spaces". Together with the river widening Weyern (Upper Mur), the river widening Gosdorf and Schladming (Enns) were awarded a prize.
