Monitoring



Reasons for river restoration

Mitigation of a pressure Pollution incident, Invasive species
Hydromorphology Quantity & dynamics of flow, Channel pattern/planform
Biology
Physico-chemical Nutrient concentrations, Specific non-synthetic pollutants
Other reasons for the project Community demand, Habitat enhancement


Measures

Structural measures
Bank/bed modifications Removal of invasive species, Depth variation, Livestock fencing
Floodplain / River corridor
Planform / Channel pattern Adding sinuosity
Other
Non-structural measures
Management interventions More sensitive channel maintenance
Social measures (incl. engagement) Awareness raising
Other
