Structural improvement of the banks on the lower Lahn (Rhineland-Palatinate) (Action A 12)

In the 19th and 20th century, numerous canalization works converted the Lahn river into a completely weir-regulated waterway with – at least in the downstream stretches - often fortified shores and very scarce possibilities to extend into the landscape.

By carrying out several small de-construction measures, the shores of the Lahn river between Diez and Lahnstein will be opened up, allowing for a more natural development.

To achieve this, it is planned to remove some of the solid bank shorings, to flatten the river banks, to broaden the affluent areas (river mouth) and to strengthen and expand existing natural structures (such as alluvial forests).


The measure serves as well to create stepping stones for connecting biotopes.
