| 520 | 3 |a"Leachates originating from landfills land industrial sites in Southern Ontario can contaminate water supplies by groundwater migration through fractures within shale bedrock. Flow and mass transport through fractures has traditionally been characterized using the parallel plate model whereby the fracture walls are approximated by parallel plates which are separated by a uniform opening. Previous studies have shown that even within relatively small areas, fractures have a much more complex geometry which must be accounted for when estimating groundwater velocity and contaminant transport. The purpose of this study is to examine in detail the nature of two single fractures within the shale in order to provide a more realistic conceptual model of flow and transport"--Abstract. |
