Actual and Predictive Transport Modeling of Fluoride Contamination of the Sfax-Agareb Coastal Aquifer in the Mediterranean Basin

Table 3

Calibrated transport model parameters of the Sfax-Agareb groundwater during October 2014.

Migration parameters	Units	Before calibration	After calibration	Description
F^− content at the source zone	mg/L	2000	250	Constant F^− concentration from the PG leachate collection basins, migrating within the sandy layer to SP4 piezometer. These concentrations are calibrated according to the concentration observed at the SP4 piezometer.
F^− content at SP4	mg/L	29	28.86	Content observed in October 2014.
Dispersivity of sand	m	15	18	Values founded by Spitz and Moreno [45].
