Abstract :

The effectiveness of geo-synthetic clay (GC) material as landfill liners using the system dynamics modeling approach is the focus of this paper. Study area is the Local Government Area (LGA)s in Ogbomosoland of Oyo State, Nigeria. These five LGAs include the urban (Ogbomoso North and Ogbomoso South) and rural (Oriire, Ogo Oluwa and Suurulere). The properties of focus on the material were hydraulic conductivity, porosity, thickness and placement slope. A mathematical model was developed by applying the governing equations coded in Visual Basic Computer programming Language. This model was validated with field data collected on the study area. The interrelationship of the properties and the breakthrough times for GC liner was found through the STELLA 9.1.4 software application. It was discovered from this research that GC liners were more effective in urban than rural LGAs. The GC liner is therefore recommended for use as landfill liner in the urban LGAs of the study area.
