Modeling of Ground Water Flow in
Walton, Okaloosa and Santa Rosa Counties, Florida

This study provides a calibrated, numerical ground water flow model for Santa Rosa, Okaloosa and Walton counties. A fully three-dimensional flow model of the principal freshwater hydrostratigraphic units has been developed. The model is calibrated to steady state, 1990 average daily rate pumping conditions for the Floridan Aquifer system and is verified using estimated pre-development conditions. Sensitivity analyses identify the impact of uncertain model parameters on the simulated behavior of the system. The calibrated flow model will serve as a baseline for conducting more detailed investigations of the transient behavior of the aquifer, for saline water intrusion analyses and for regional water supply planning.
