Project Summary

The Alpine Region is regarded as the most valuable source of clean drinking water in Europe and of great importance for hydro power use. Management of water as an extremely valuable resource is guaranteed by numerous reservoirs enabling a third essential task: flood protection. Sediments are transported in rivers originated from natural geomorphologic processes in alpine regions accumulating material in reservoirs. Thus storage capacity is reduced interfering with the needs of water supply, flood protection and hydro power. However, the lack of transported material in downstream sections heavily affects ecological variety, river bed stability and groundwater. The project aims on a wise management of sediments on basis of experiences gained on national level to establish trans-national guidelines taking into account the EU Water Framework Directive and spatial development needs to preserve existing reservoirs and to avoid uncontrolled exploitation by constructing new storage capacity.

Project Objectives

As flood protection is a major task and of high public interest trans-national strategies are needed to implement a sustainable management aiming on a dynamic balance to avoid reservoir sedimentation as well as degradation processes of rivers in the peri-alpine belt to reduce the risk of floods and to avoid severe damages to infrastructure and private property. Accumulation in reservoirs reduces valuable morphological processes of rivers downstream affecting biologic diversity and ecologic dynamics.

Project Achievements

Comprehensive guidelines on sedimentation processes in the Alpine region for enhanced taining of water authorities, local administrations and private businessesSeven typical Alpine reservoirs were selected for pilot projects ranging from a high region facility directly influenced by glacier activity down to peri-alpine belt river reservoirs to cover most sedimentation problems in the Alpine region. The activities are focussed on different strategies to transfer or remove sediments in a larger scale taking into consideration the fragile environment of the Alps.A data base will be implemented to gather information about reservoirs of different geometry and operational procedures. Immediate information of local authorities and all relevant interest groups (inhabitants, fishermen, land owners) can reduce disputes significantly. Experiences of how to encourage locals to join the planning process will be shared within the partnership and published as recommendations to administrations and reservoir owners.
