4.1. Model Framework

Try these first

1. 1.

   What is diffusion?

   Hint

   Think about how a drop of dye spreads in water.

2. 2.

   What does TSS stand for?

   Hint

   It's related to water clarity.

3. 3.

   What mechanism allows particles to be lifted from the sediment into the water?

   • Diffusion
   • Advection
   • Resuspension

   Hint

   Think about storm impacts.

4. 4.

   Is bioturbation a passive process?

   • True
   • False

   Hint

   Consider the role of living organisms.

5. 5.

   Calculate how a specific concentration of chemicals in sediment affects nearby water quality, considering diffusion and resuspension rates observed during a storm.

   Hint

   Make sure to account for different flow rates.

6. 6.

   Propose a mitigation strategy for reducing the impact of sediment contamination following a heavy rain event in a lake ecosystem.

   Hint

   Think about natural solutions versus engineering interventions.
