Monitoring



Reasons for river restoration

Mitigation of a pressure Riparian development, Flood defence
Hydromorphology Structure & condition of riparian zones
Biology
Physico-chemical
Other reasons for the project Recreation, Community demand, Landscape enhancement


Measures

Structural measures
Bank/bed modifications reforestation, Reduction of bank slope
Floodplain / River corridor Excavation for floodplain creation, Requalification and improvement of forestal cover along corridor, Alloctone species control
Planform / Channel pattern
Other
Non-structural measures
Management interventions Monitoring strategy
Social measures (incl. engagement)
Other Consultation
