Discuss-role of wetlands in sediment and pollutant transport


Assignment:

Part. 1: Make sure each response is at least 150 words and all sources must be cited APA format.

1. What are wetlands? How are they formed? Please explain in some detail the physical and hydrological conditions under which wetlands are formed.

2. What are mangroves? What is the important characteristic of the way they operate?

3. Explain the differences between a gully, ravine, and valley. How are gullies formed? Why are gullies important?

4. Explain how surface erosion can be controlled, or at least maintained at acceptable levels in different landscapes and vegetative types.

5. Explain the differences between laminar and turbulent flow, and between subcritical and supercritical flow. On the same topic: what are the Reynolds and the Froude numbers?

6. Explain the relationships between stream capacity and sedimentation. Why is it important to have a good idea on the sedimentation potential of a stream?

Part. 2: Create a minimum of 1,050-word paper that compares and contrasts three different types of wetlands.

Include the following:

• A general synopsis of wetlands and their functions.

• A discussion of the components that make up a wetland

• The ecological significance of wetlands.

• The role of wetlands in sediment and pollutant transport.

• At least one peer reviewed journal article that highlights the hydrological importance of at least one of the wetland types you chose.

Utilize APA formatting for your paper and references.
