Challenge Problems

Push your limits with challenges.

Question 1

In a hypothetical experiment using a falling head permeameter, water is poured into the standpipe and the head drops from 60 cm to 20 cm in 15 minutes. Calculate the permeability of the soil if the standpipe's cross-sectional area is 5 cm² and the soil sample area is 100 cm².

💡 Hint: Remember to convert units where necessary and apply the appropriate equations.

Question 2

A civil engineer finds that seepage into a foundation is causing erosion. How would you model this situation using the continuity equation and what preventive measures would you suggest?

💡 Hint: Think about how the water moves and the structures around it.
