6.2. Model Parameters and Solutions

Try these first

1. 1.

   What process involves the movement of chemicals from high to low concentration?

   Hint

   Think about how perfume spreads in a room.

2. 2.

   What is the effect of resuspension on water quality?

   Hint

   Consider what happens after heavy rain.

3. 3.

   What mechanism primarily describes the upward movement of contaminants due to bulk water flow?

   • Diffusion
   • Advection
   • Resuspension

   Hint

   Think about how wind moves things in the air.

4. 4.

   True or False: Bioturbation can slow down the diffusion process.

   • True
   • False

   Hint

   Consider what worms do in sediment.

5. 5.

   A body of water experiences high levels of resuspension after a storm. How would you model the changes in water quality parameters such as TSS and contaminant levels over time?

   Hint

   Think about how sediment transport occurs and relate it to water quality metrics.

6. 6.

   Design an experiment to quantify the impact of bioturbation on chemical release in sediments. What controls would you implement?

   Hint

   Consider what biological factors can be monitored in your design.
