Challenge Problems
Push your limits with advanced challenges
A sediment sample has a total concentration of 250 mg/kg, and the bulk density is 1200 kg/m3. Calculate the expected pore-water concentration, given that the moisture content is 15%.
💡 Hint: Identify how moisture affects your calculations.
You collect sediment samples from a river and notice varying concentrations at different depths. Discuss how you would model this concentration profile and reason your choice of numerical methods.
💡 Hint: Focus on why numerical solutions are essential for non-uniform concentration distributions.
