Reasons for river restoration

Mitigation of a pressure
Hydromorphology Quantity & dynamics of flow, Channel pattern/planform, Width & depth variation, Continuity for organisms
Biology Fish: Species composition, Fish: Abundance
Physico-chemical
Other reasons for the project Community demand, Fisheries


Measures

Structural measures
Bank/bed modifications Regrading, Introduction of spawning gravels
Floodplain / River corridor
Planform / Channel pattern Creation of new channel, Adding sinuosity
Other
Non-structural measures
Management interventions
Social measures (incl. engagement)
Other Information provision, Consultation, Participation in design, Participation in monitoring
