Chapter 28, Problem 13RQ

To determine

The greater transporter of sediment and its reason.

Answer to Problem 13RQ

The greater transporter of sediment is a turbulent flow and the reason is due to its faster currents greater volumes of sediments can be transported.

Explanation of Solution

The sediment present on the surface of Earth is driven by the water flow. The pattern, in which the water flow has the greatest effect on the landscape. When moving erratically downstream, it takes away everything that comes in contact with it. This pattern is known as turbulent flow.

On the other hand, laminar flow occurs when the flowing water moves without mixing of any sediment. A turbulent flow can carry the small as well as the large particles of sediment, depending on its speed. Moreover, the movement of sediments also depends on the channel geometry and speed of flow.

Conclusion:

Therefore, the greater transporter of sediment is a turbulent flow and the reason is due to its faster currents greater volumes of sediments can be transported.
