Plot of Groundwater Calibration Statistics
• L-5844 is located on the edge of a ravine and the model elevation is 6 feet higher than the actual elevation, so calibration is off
• All other stations are either good or OK

Summary of Calibration
• Good calibration overall• Some instabilities in the model for the Estero River and some
groundwater stations east of I-75• Spring Creek flow calibration not as good as desired, however
measured data for the split of flows between the north and south Branch are not available
• Calibration of Halfway Creek was achieved by adjusting irrigation parameters and modifying rainfall runoff process to account for stormwater detention
• The model is ready for design storm modeling, but as we will see in the next presentation, the design storm modeling uncovered some small flaws that are being fixed
