Reasons for river restoration

Mitigation of a pressure Depletion of Macrophytes communities
Hydromorphology Quantity & dynamics of flow, Flow velocities, Width & depth variation, Continuity for organisms
Biology Macrophytes, Invertebrates, Fish: Species composition, Fish: Abundance
Physico-chemical Nutrient concentrations, Oxygen balance
Other reasons for the project Landscape enhancement


Measures

Structural measures
Bank/bed modifications
Floodplain / River corridor Water release into floodplain in winter, Closing of sluice in summer, Future floodplain lowering
Planform / Channel pattern Creation of side channel
Other
Non-structural measures
Management interventions more natural reservoir releases
Social measures (incl. engagement)
Other
