Principles and processes of sediment transport - Factors controlling the movement of sediment
7 important questions on Principles and processes of sediment transport - Factors controlling the movement of sediment
What are the four modes of sediment transport?
2. Rolling (=bedload) (occurs in slower flow)
3. Saltation (=bedload) (occurs in faster flow)
4. Suspension (=suspended load) (seldom in contact with the bed) (occurs in faster flow)
What is a boundary layer?
What feature exist between two water layers?
- Higher grades + faster learning
- Never study anything twice
- 100% sure, 100% understanding
What is the benthic boundary layer?
Where does the extent of sediment transported depend on?
What are other factors controlling the sediment transport?
- Viscosity of the water
- Laminar or turbulent flow
What is the difference between cohesive and non-cohesive sediments?
In non-cohesive sediments there is a lack of physico-chemical interaction, so the particles are free to move independently.
The question on the page originate from the summary of the following study material:
- A unique study and practice tool
- Never study anything twice again
- Get the grades you hope for
- 100% sure, 100% understanding
