AW. 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?
