Monitoring



Reasons for river restoration

Mitigation of a pressure
Hydromorphology Quantity & dynamics of flow, Continuity of sediment transport
Biology Macrophytes, Fish: Species composition
Physico-chemical
Other reasons for the project Recreation, Landscape enhancement


Measures

Structural measures
Bank/bed modifications Decrease sedimentation
Floodplain / River corridor Creation of side channel
Planform / Channel pattern Increase river dynamics, Re-connect tributaries to main channel
Other
Non-structural measures
Management interventions
Social measures (incl. engagement)
Other
