impacts from pumping,
canal level settings, etc. as
part of this investigation
IWRMMP IWRMMP -- FloridanFloridan
• I modified existing
SEAWAT model
• Extent based on maximum
projected drawdown

of Broward County
• Additional layer added to
UFARefined Model Extent
IWRMMP IWRMMP -- FloridanFloridan
• 14 layers from ground
surface to the Boulder

IWRMMP IWRMMP -- FloridanFloridan
• I recalibrated the model to better
calibration statistics than the original
• I developed and ran several predictive
scenarios
− Simulated through 2035
− Evaluated potentiometric surface and TDS
− Injection wells evaluated
IWRMMP IWRMMP -- FloridanFloridan
• Well locations
− Various
combinations used
in scenarios
− Regional and/or
injection wells not
used in every
scenario
IWRMMP IWRMMP -- FloridanFloridan
• Broward County production rates
− 80 MGD in 2025
− 103 MGD in 2035

pumping at individual utility wellfields
− With and without injection
− Pumping at individual wellfields until 2025
• Additional pumping in regional wellfields after
2025
