Challenge Problems
Push your limits with challenges.
Question 1
Given a sediment layer with known bulk density, calculate the impact of bioturbation by organisms on diffusion rates. Assume a 15% increase in pore space due to bioturbation.
💡 Hint: Use the relationship between pore space and effective diffusivity.
Question 2
Examine a scenario where methane is produced in an anaerobic sediment environment. Calculate how this gas might influence chemical transport through advection.
💡 Hint: Sketch a diagram of gas movement and consider how it impacts nearby chemicals.
