  6. Testing Management Options

  7. Assessing the effectiveness of Management Scenarios

  8. Changes in Land-use/Land Management Practices • Corn  Brome grass • Rate of recharge 12 in/yr → 16.5 in/yr • Corn  Medium Density Residential • Rate of recharge 12 in/yr → 8.3 in/yr • Corn  Corn-winter Wheat • Rate of recharge 12 in/yr → 11.5 in/yr
