SEAWAT model

• Extent based on maximum

projected drawdown

Boulder Zone represented

with Constant Heads

Simulated Upper Floridan Water Elevation


• 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


• Well locations

− Various

combinations used

in scenarios

− Regional and/or

injection wells not

used in every

scenario


• Broward County production rates

− 80 MGD in 2025

− 103 MGD in 2035

• Broward County injection rates

− 52.75 MGD from 2025 through 2035

• Representative predictive simulations:

pumping at individual utility wellfields

− With and without injection

− Pumping at individual wellfields until 2025

• Additional pumping in regional wellfields after

2025
