1.7. Next Steps: Gaussian Dispersion Model Derivation

Try these first

1. 1.

   What is the main purpose of a dispersion model?

   Hint

   Think about where pollutants might go after being released.

2. 2.

   What does mass balance refer to?

   Hint

   Consider the concept of net gain or loss.

3. 3.

   What is the general principle of a mass balance equation?

   • Rate in = Rate out
   • Rate in > Rate out
   • Rate in < Rate out

   Hint

   Consider the concept of equilibrium.

4. 4.

   True or False: In an Eulerian model, we track moving particles.

   • True
   • False

   Hint

   Think about the reference frame used in the model.

5. 5.

   A factory emits pollutants at a constant rate. How would you model the dispersion of these pollutants over time using the Gaussian model?

   Hint

   Start by outlining the inputs and outputs of pollutants.

6. 6.

   Discuss the implications of introducing a chemical reaction in the plume. How would this alter your model?

   Hint

   Think about how reactions consume or produce substances in a given volume.
