3D numerical hydrodynamic models
Type
Hydromorphological models
Basic principles
Fundamental equations for conservation of water mass and water flow momentum, time-averaged over all turbulent fluctuations (RANS = Reynolds Averaged Navier-Stokes equation) or time-averaged over only the smaller turbulent fluctuations (LES = Large Eddy Simulation)
Outputs
Flow velocities, water depths, water levels, flow shear stresses
Rivertypes
Related Pressures
- Surface water abstraction
- Groundwater abstractions
- 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
- Other pressures
Related Measures
- Improve/Create water storage
- 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
- 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
