Question 1.
What does the coefficient of permeability (k) measure?
Show hintHide hint
Think about what water does when it interacts with soil.
Question 2.
Name one factor that can influence soil permeability.
Show hintHide hint
Consider the characteristics of the soil.
3Question 3.
Which type of soil has the highest permeability?
- Clay
- Sand
- Gravel
Show hintHide hint
Think about the sizes of the particles.
4Question 4.
True or False: Permeability is only dependent on the size of soil particles.
- True
- False
Show hintHide hint
Consider other factors that can influence flow.
Question 5.
You have two soil types: sand with a permeability of 0.1 cm/sec and clay with a permeability of 10^-8 cm/sec. If both are placed in an aquifer, calculate the effective flow rate assuming equal hydraulic gradient.
Show hintHide hint
Consider how permeability affects flow differences.
Question 6.
You have a mixture of soil with 70% sand and 30% clay. Discuss how the overall permeability will compare to pure sand and pure clay.
Show hintHide hint
Think about how the combination of particles affects flow.
