become effective only in extreme events, and shape the channel for normal floods with a more flexible
technique, and in particular respect the natural planform alignment.
Review Questions
1. Explain under what conditions the channel incision occurs?.
2. What are the main causes of river channel incision?
3. What are the naturally developed bed structures that resist channel incision?
4. Under what conditions can the step-pools develop?
5. If the step-pools develop in a river, what are the features of the river?
6. Explain the functions of the knickpoints in morphological processes.
7. What environmental and societal effects may be induced by channel incision?
8. How can people control the incision?
9. You are a manager of an incised river, work out a plan to mitigate the impacts of channel incision on
environment and ecology.
10. Explain the landscape development during the channel incision process, provide some examples.
