Bank dynamics models
Type
Hydromorphological models
Basic principles
Geomechanical equations for bank stability, possibly combined with equations for river flow (or interface with hydrodynamic or morphodynamic model) and equations for groundwater flow (or interface with groundwater model).
Outputs
Bank stability, bank geometry, rate of bank retreat, amount of bank erosion products.
Rivertypes
Related Pressures
- Hydropeaking
- Sediment discharge from dredging
- Reservoir flushing
- Hydrological regime modification
- Interbasin flow transfers
- Discharge diversions and returns
- Alteration of instream habitat
- Sand and gravel extraction
- Sedimentation and sediment input
- Embankments, levees or dikes
- Loss of vertical connectivity
- Impoundment
- Alteration of riparian vegetation
- Channelisation / cross section alteration
Related Measures
- 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
- Develop riparian forest
- Remove non-native substratum
- Adjust land use to develop riparian vegetation
- Revegetate riparian zones
- Remove bank fixation
- Adjust land use to reduce nutrient, sediment input or shore erosion
