1.4.1. Erosion and Sediment Control

Try these first

1. 1.

   What is one method to prevent erosion during construction?

   Hint

   Think about barriers.

2. 2.

   What is stormwater?

   Hint

   It’s related to rain.

3. 3.

   What is the purpose of a silt fence?

   True or False: Retention ponds help reduce water flow into local streams.

   • True

   Hint

   Consider how water moves after it rains.

5. 5.

   Evaluate a construction site that has no erosion control measures. Discuss the potential impacts on local water bodies and suggest an erosion control plan.

   Hint

   Assess the situation holistically - consider ecological and mitigation factors.

6. 6.

   Analyze a case where a stormwater management plan was ineffective in controlling runoff. What went wrong and how would you redesign the plan?

   Hint

   Focus on the reasons for failure and easy improvements.
