Project Modeling ORP-Ph David Zeitoun

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.

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.

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)
