This refers to locally limited widening of channels
to benefit people and the environment.

Channel widening can rehabilitate regulated watercourses and reduce the extent of streambed erosion and the risk of flooding. Widening the river gives it the opportunity for self-dynamic development of a typical equilibrium. |

Objectives of widenings:
|
| |
Streambed stabilisation |
| |
Flood control |
| |
Improvement of water quality |
| |
Ecological enhancement |
| |
Increased value as a recreational area |
