Reasons for river restoration

Edit reasons for 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

Edit Measures

Structural measures
Bank/bed modifications	Remove revetments, Bed-raising
Floodplain / River corridor	increase floodplain connectivity
Planform / Channel pattern	Channel narrowing
Other	create more natural flow regime, Install fish passes, Re-connect backwater and wetlands, weir removal
Non-structural measures
Management interventions
Social measures (incl. engagement)
Other
