Description of solution
Between 1860 and 1890 the Untere Salzach has been strongly regulated and several hydroelectric power plants were built. All together this lead to increased depth erosion. To prevent bridges, walls and dikes from getting undermined Bavaria and Austria used NBS. To stabilze the river bed 2009/2010 a river bed ramp has been built. To improve the bedload budget it is also planned to make more room for the river. The bank protection will be removed and structural measures (e.g. the implemention of deadwood) to improve the ecological situation will be implemented.
