The College of Civil Engineering panel PhD dissertation on (performance of a clay Liner Barrier in a Sanitary Landfill)
The College of Civil Engineering at the University of Technology awarded a PhD in Geotechnical Engineering to student Kawthar Yalli Hussein for her dissertation entitled:
Performance of Clay Liner Barrier in Sanitary Landfill
This study investigated the performance of different landfill barrier systems to enhance environmental sustainability by reducing leachate migration and groundwater contamination. The study used a simulation of landfill conditions using a lysimeter to simulate real landfill environments.
The results of this dissertation demonstrated that the use of a lysimeter system with an advanced sensing and monitoring system enabled a realistic simulation of the performance of landfill barriers. Experiments showed that modifying clay with materials such as WTSA, MgO, graphene, and bentonite significantly improved the permeability and mechanical resistance properties. Graphene and MgO-reinforced liners outperformed in reducing permeability and increasing cohesion, while stone columns contributed to load distribution and reduced deformations.
The study concluded that merging geotechnical improvements with structural reinforcements provides a more efficient and sustainable barrier system.
