Sediment Transport
This quiz is designed to test your knowledge of sediment transport, a fundamental process in hydraulic engineering. The questions cover various aspects of sediment transport, including its modes, governing factors, and implications for river engineering and management.
Questions
Which of the following is NOT a mode of sediment transport?
- Bed load
- Suspended load
- Wash load

The primary factor governing the initiation of sediment transport is:
- Flow velocity
- Sediment size
- Sediment density
- Water temperature
Which of the following sediment characteristics has the greatest influence on its transportability?
- Size
- Shape
- Density
- Mineralogy
The term 'competence' in sediment transport refers to:
- The ability of a flow to transport sediment of a given size
- The maximum size of sediment that can be transported by a flow
- The rate at which sediment is transported by a flow
- The distance over which sediment is transported by a flow
Which of the following factors can increase the sediment transport capacity of a river?
- Increased flow velocity
- Decreased water depth
- Increased sediment size
- Increased channel roughness
The process by which sediment is deposited from a flowing fluid is known as:
