Dr. Mustafa Eissa

Dr. Eissa was granted his PhD in hydrogeology and flow modeling from the University of Nevada Reno, USA in August 2012. He worked as a graduate research assistant in the hydrologic science division at the Desert Research Institute for five years from September 2007 to September 2012. Currently, he is a visiting researcher at IT² conducting research with Dr. Orfan Shoukar Stash concerning carbon dating, characterization of seawater intrusion, determination of groundwater recharge sources and contaminant transport, water resource portability, and sustainability in coastal aquifers.

Research Interests:

My research interests focus on groundwater resource sustainability, isotopes tracing, water-rock interactions, geochemistry, sea water intrusion, groundwater management, and solute transport. I am interested in groundwater modeling and analytical and numerical solutions (MODFLOW, SEAWAT) for assessing groundwater flow. My PhD dissertation focused on water-rock interactions, geochemical modeling (NETPATH), multi tracer isotopes, and groundwater sustainability in the Wadi Watir watershed, Sinai, Egypt. The main objectives of my dissertation are for the determination of groundwater recharge sources in the Wadi Watir watershed. This research will allow better groundwater management downstream, in the quaternary coastal aquifer to avoid seawater intrusion from the Gulf of Aqaba, and upwelling of deep saline layer in this aquifer, using a 3-D variable-density flow model (MODFLOW/SEAWAT). I also utilize different isotopic tracers (¹⁴C, ¹³C, ¹⁸O, ²H, ³⁷Cl, ⁸¹Br, ⁸⁷/⁸⁶Sr and¹¹B) that have an impact on the determination of groundwater recharge sources, seawater, and rock water interactions. In addition, I am working towards quantifying the annual groundwater recharge for local hydrogeological basins using analytical and numerical models.
