0D analytical models for flow in compound cross-sections
Type
Hydromorphological models
Basic principles
Fundamental equations for conservation of water mass and water flow momentum under the assumption of steady uniform flow, spatially averaged over cross-section segments and time-averaged over all turbulent fluctuations
Outputs
Flow velocities, water depths, water levels, flow shear stresses
Rivertypes
Related Pressures
- Surface water abstraction
- Groundwater abstractions

- Interbasin flow transfers
- Discharge diversions and returns
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
- 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
