Isar restoration at the Bibermühle

    Solution ID
    Description of solution
    Summary (Challenges; Objectives)

    In the 1920s and 1930s the originally strongly branched course of the Isar river between Bad Tölz and Lenggries was forced into a single, slightly curved riverbed. Cylindrical gabions and large hydraulich construction stones have been securing the banks. Due to these actions impiortant habitats for flora and fauna were lost. To restore these habitats the river bank protection and the cylindrical gabions were removed. This allows the Isar to widen naturally and new habitats can develop. Additonal depth erosion can be prevented by the new load budget. 

    Technical characteristics

    800 m removal of the bank protection, around 23.000 m³ material removal from the embankments. Over 14.000 m³ were deposited in the river bed.
