CHANGES IN RIVER CHARACTERISTICS DOWNSTREAM
In the box on left hand side of the diagram, put one of the following symbols:
An arrow pointing upwards: if the variable increases downstream
An arrow pointing downwards: if the variable decreases downstream
A horizontal arrow: if the variable stays the same
| Velocity of the water flowing in the channel (V) | |
| Channel roughness (shown by 'Manning's 'n' coefficient) | |
| Friction between the water and the bed/banks | |
| Channel width | |
| Channel depth | |
| Turbulence within the channel | |
| Cross-sectional area (A) | |
| Discharge of the river (Q) | |
| Size of particles making up the load | |
| Angularity of the bedload | |
| Channel gradient | |
| Channel efficiency (as shown by hydraulic radius) |
