Innovative approach for dam restoration
INADAR is connecting the requirements of flood protection and nature conservation.
Core of the innovative approach for dam restoration are the so-called “eco-berms”, which do not only contribute to dam restoration (and elevation), but also improve the ecological situation at the river banks. In contrast to the classical dam elevation the necessary widening can be carried out on the water side of the dam. This protects the ecosystem on the air side of the dam.
The eco-berm has two parts, which are shown schematically in the Figure below. On the one hand the eco-berm consists of infrastructural measures for the restoration and elevation of the dam. The other part includes ecological measures for the environmental improvement of dams and the storage space.
An essential component of the LIFE-project is to document and evaluate the implementation of the measures. The intention is to assess how the different habitats are accepted. The monitoring is carried out by the University of Innsbruck and the Aueninstitut Eichstätt. In the first step the evaluation concept aims to illustrate the actual state, which serves as a reference situation for the assessment of the effects. With the help of appropriated technical and ecological indicators, the change can be compared to the reference state. This is done at several times, e.g. immediately after implementation of the measures, one year after implementation of the measures and at the end of the project, two years after the implementation.
