Excerpt from Appendix of the Draft Environmental Impact Statement for Tusayan Growth: Kaibab National Forest To simulate equilibrium or steady-state aquifer conditions, the groundwater flow model was calibrated to geologic structural features, reported groundwater levels at existing wells, and reported discharge from Havasu, Indian Garden, and Hermit Springs. Transient conditions were then simulated to project potential effects of groundwater withdrawal at selected durations, locations, and pumping rates. The transient conditions were simulated by 1) using the equilibrium conditions computed from 'the calibrated steady-state flow model as the initial conditions; 2) applying pumping stresses to the model at selected locations and pumping rates; and 3) computing the drawdown in groundwater levels and decrease in discharge from springs after 5, 50, and 100 years of pumping. Sensitivity analyses were conducted to evaluate the effects of varying model input parameters on steady-state and transient model results.
