Reasons for river restoration

Mitigation of a pressure Riparian development, Reservoir impoundment
Hydromorphology Continuity for organisms, Structure & condition of riparian zones, Quantity & dynamics of flow, Flow velocities, Continuity of sediment transport, Channel pattern/planform
Biology Fish: Abundance
Physico-chemical
Other reasons for the project Landscape enhancement


Measures

Structural measures
Bank/bed modifications Bed raising, Removal of revetments, Weir removal
Floodplain / River corridor Floodplain reconnection
Planform / Channel pattern Channel narrowing
Other Create more natural flow regime, Re-connect backwater and wetlands, Creation of fish passes
Non-structural measures
Management interventions
Social measures (incl. engagement)
Other
