Director of the Environmental Research Center the head of the Master's Thesis Discussion Committee

Professor Dr. Zainab Baha Mohammed, Director of the Environmental Research Center, supervised the discussion of the master's thesis of the student (Ahmed Safaa Karim) Department of Civil Engineering, specialization (Environmental Engineering) for his research entitled
‏Investigation of microplastics in surface water (river, dam, and marsh) a case study of the Tigris River
‏The researcher addressed in his thesis the treatment of plastic waste from 14 sites in the Tigris River, eight of which are in Baghdad Governorate, 3 in Kut Governorate, and 3 in Maysan Governorate
‏The researcher concluded that the addition of high and low activity WCA (0-15%) to the contaminated soft soil improved the compaction by reducing the compaction index (Cc) from 0.094 to 0.027 and the swelling index (Cr) from 0.0166 to 0.003 and 0.0064, respectively. In addition, the volumetric change coefficient and permeability decreased. With the increase of high and low activity WCA (15%), the volumetric change coefficient (kPa-1) decreased from 0.008 to 0.002, and from 0.008 to 0.004, respectively, and the permeability decreased from 2.7 to 0.04 (10-4) (mm)/s) and from 2.7 to 0.61 (10-4) (mm/s).
