Interactive Quizzes
Engage in quick quizzes to reinforce what you've learned and check your comprehension.
Question 1
What equation represents Darcy's Law for unsaturated flow?
- q = K * (dh/dz)
- q = -K(θ) * (dh/dz)
- q = K + (dh/dz)
💡 Hint: Look for the negative sign involved in the formula.
Question 2
True or False: Hydraulic conductivity increases in compacted soils.
- True
- False
💡 Hint: Consider how compaction affects water flow.

Challenge Problems
Push your limits with challenges.
Question 1
Calculate the flux of water in a sandy soil with a hydraulic conductivity of 10 cm/hr and a matric potential gradient of 0.5. Use Darcy's Law.
💡 Hint: Remember to multiply the hydraulic conductivity by the gradient.
Question 2
If a compacted clay soil has a hydraulic conductivity of 1 cm/hr, how does this affect irrigation scheduling compared to a loamy soil with 5 cm/hr?
💡 Hint: Think about how the differences in hydraulic conductivity will influence water availability for crops.
