Question 1
What is advection?
- The process of diffusion
- Movement of fluid carrying substances
- A type of pollution
💡 Hint: Think about how fluids carry objects downstream.
Question 2
True or False: Diffusion is always the dominant process in moving pollutants in flowing water.
- True
- False
💡 Hint: Consider the speed of flowing rivers versus still waters.

Challenge Problems
Push your limits with challenges.
Question 1
A chemical spill occurs in a river where flow velocity is measured at 2 m/s. If diffusion coefficient for the pollutant in water is 1 x 10^-5 m^2/s, calculate the effective transport mechanism when both processes co-exist.
💡 Hint: Compare coefficients of both processes.
Question 2
You are tasked with modeling the pollutant transport in a groundwater system. How does the porosity of the soil impact both advection and diffusion?
💡 Hint: Consider how fluid can move through water-saturated systems.
