7. Given Darcy's Law describing saturated flow of water in soil: Q = A x Katx . Explain each term in

this equation. What is the most important, flow-rate-limiting term in the equation and why? How

might you use Darcy's Law to evaluate risk of, for example, contaminant leakage or failure of an

earthen dam?

8. Macropores and micropores are defined based on a specific diameter measure, and operationally.

Define macropore and micropore both ways. How can you estimate the % macropore space and %

micropore space in soil using information in Table 1?
