1.1. Transport of Pollutants - Gaussian Dispersion Model

Try these first

1. 1.

   What is the main assumption in mass balance?

   Hint

   Think about what happens to pollutants over time.

2. 2.

   Define the Eulerian model.

   Hint

   Relate this to fixed points versus moving particles.

3. 3.

   What does the Gaussian Dispersion Model primarily predict?

   • Atmospheric temperature
   • Pollutant concentrations
   • Humidity levels

   Hint

   Consider the purpose of the model discussed.

4. 4.

   True or False: The Lagrangian model is used for fixed reference frames.

   • True
   • False

   Hint

   Think about how each model approaches tracking pollutants.

5. 5.

   Given a constant emission rate of pollutants into the atmosphere, derive the expected concentration profile using the Gaussian dispersion model.

   Hint

   Incorporate changes in environmental conditions and analyze their effect on the equation.

6. 6.

   Discuss how varying wind speeds affect the dispersion model's predictions in urban areas.

   Hint

   Think about the direct impact of wind on pollutant movement in real-world scenarios.
