1.5. Emergency Response Planning Using Dispersion Modeling

Try these first

1. 1.

   What is the function of a Gaussian dispersion model?

   Hint

   Recall the main purpose of the model.

2. 2.

   Define stability class.

   Hint

   Think about how weather influences air quality.

3. 3.

   What is the primary purpose of Gaussian dispersion modeling?

   • To create pollution maps
   • To estimate pollutant concentrations
   • To minimize emissions

   Hint

   Focus on what the model actually calculates.

4. 4.

   True or False: Contour maps help visualize pollutant concentration levels.

   • True
   • False

   Hint

   Think about why we’d need a map for pollution.

5. 5.

   Given a stack emitting 100 grams/second of CO2 at a height of 75m in a Stability Class C area, calculate the concentration at 200m downwind and explain how wind direction might alter this.

   Hint

   Make sure to reference stability classes' impact on dispersion.

6. 6.

   Draft a comprehensive emergency response plan for a hypothetical chemical spill in an urban area, including at least three key actions based on predicted pollutant dispersion.

   Hint

   Think about the importance of mapping and analysis for effective response.
