Study concerning the flood effects of the rivers Aar and Palmbach on the city of Diez and further municipalities (Action A 4)

The Lahn and its tributaries Aar and Palmbach are squeezed into narrow beds and often have little space to expand at high water levels without affecting people and cities along its shores.

In order to give back some space to the Lahn, the LIFE project "Living Lahn" negotiates for additional retention areas next to the Lahn and along its tributary rivers, such as the Aar and Palmbach, thus reducing the flood risk for nearby city of Diez and other neighbouring municipalities.
