1. Project Modeling ORP-Ph
David Zeitoun

2. Model Two models were used: ORP Diffusion in the Groundwater
Redox Equations combines with Transport of chemical species in the unsaturated vadose zone
2. Ph changes in the Groundwater
Diffusion of Air Bubbles in the flowing water combines with transport equations.

3. Model The models determines: At different depth and time
The ORP concentration in ppm from the beginning of the reactor action.
2. At different depth and time
The Ph concentration in the groundwater.

4. Model Calibration The model was calibrated using
The field tests results (Retardation factor)
The log of the well K6
The soil parameters according to the literature on the coastal aquifer (Mercado-Zeitoun-Melloul)
