Reasons for river restoration

Mitigation of a pressure
Hydromorphology Structure & condition of riparian/lake shore zones, Channel pattern/planform
Biology Invertebrates, Macrophytes, Fish
Physico-chemical Specific non-synthetic pollutants
Other reasons for the project Habitat creation, Landscape enhancement


Measures

Structural measures
Bank/bed modifications Habitat restoration
Floodplain / River corridor Creation of backwaters, BAP habitat creation, Creation of wetlands, Creation of backwater and ponds
Planform / Channel pattern Introduction of backwaters, Reconnect and restore aquatic habitats
Other
Non-structural measures
Management interventions Ensuring biodiversity, Woodland management, Promoting riparian vegetation
Social measures (incl. engagement)
Other
