- Reduce water consumption
- Increase minimum flows
- Recycle used water
- Improve water retention
- Reduce surface water abstraction with return
- Water diversion and transfer
- Reduce surface water abstraction without return
- Reduce groundwater extraction
- Reduce anthropogenic flow peaks
- Modify hydropeaking
- Shorten the length of impounded reaches
- Increase flood frequency and duration in riparian zones or floodplains
- Favour morphogenic flows
- Link flood reduction with ecological restoration
- Ensure minimum flows
- Manage aquatic vegetation
- Establish environmental flows / naturalise flow regimes
- Facilitate downstream migration
- Manage sluice and weir operation for fish migration
- Remove barrier
- Install fish pass/bypass/side channel for upstream migration
- Modify culverts, syphons, piped streams
- Fish-friendly turbines and pumping stations
- Create low flow channels in over-sized channels
- Narrow water courses
- Widen water courses
- Allow/increase lateral channel migration or river mobility
- Remeander water courses
- Shallow water courses
- Improve backwaters
- Lower river banks or floodplains to enlarge inundation and flooding
- Isolation of water bodies
- Reconnect backwaters and wetlands
- Remove hard engineering structures that impede lateral connectivity
- Construct semi-natural/articificial wetlands or aquatic habitats
- Set back embankments, levees or dikes
- Restore wetlands
- Retain floodwater
