“Geofilters”
Presented by:
R. Jonathan Fannin, Ph.D., P. Eng.
University of British Columbia
Vancouver, Canada;
DATE: Wednesday October 8, 2014, 1:00 – 2:00 pm EST
ABSTRACT: The origins of current design practice for a granular filter are first examined, along with some of the lessons learned over the years from construction of very large embankment dams, including the WAC Bennett dam in British Columbia. The origins of current design practice for a geotextile filter are then examined, in conjunction with some of the lessons learned from their use in earthworks, including the rehabilitation of the Alouette dam spillway in British Columbia. The evidence to-date suggests that both sand-gravel filters and geosynthetic filters have generally performed well at controlling seepage flow in earthwork applications for many years. However there have also been problems reported, both for granular filters and for geotextile filters. This lecture draws upon industry-university research on the sinkhole incident at the WAC Bennett dam in British Columbia, and industry-university research on the filter compatibility of geotextiles in unidirectional and reversing flow, to understand better the significance of issues affecting the performance of geofilters in earthworks. The merits of mandating the use of a geosynthetic filter as an adjunct to a granular filter, in critical infrastructure, are then considered within the context of risk management.
ABOUT THE SPEAKER: Jonathan Fannin obtained a B.Sc. (Civil Engineering) from the Queen’s University of Belfast, and a D. Phil. (Geotechnical Engineering) from the University of Oxford for studies on geosynthetics for soil stabilization. He is a recipient of several awards, including an IGS Award for contributions of laboratory and field research to engineering practice, a CGS Quigley Award for the best paper in the Canadian Geotechnical Journal, a Karl Terzaghi Fellowship from the Norwegian Geotechnical Institute and most recently, a Distinguished Visiting Fellow award from the U.K. Royal Academy of Engineering. Jonathan has provided specialist technical advice on a number of dam projects in North and South America and, in 2013, was made a Fellow of the Engineering Institute of Canada in 2013.

“Composite Drainage Nets – Design and Testing”
Presented by:
Bob Mackey, P.E., BCEE
S2L, Incorporated
Maitland, Florida, USA
DATE: Wednesday July 9, 2014, 1:00 – 2:00 pm EST
ABSTRACT: The development of composite drainage nets (CDNs) (a.k.a. “geocomposites”) has advanced from the initial biaxial nets to tri-axial nets to the current composite drainage products of various geosynthetic materials and structures. The use of CDNs requires a fundamental knowledge of the CDN components and the specifications for those materials.
This North American Geosynthetics Society webinar will address the various design, testing and installation issues one must consider with composite drainage nets. Issues include:

“Recent insights on the performance of GCLs in bottom liners and covers”
Presented by:
R. Kerry Rowe
GeoEngineering Centre at Queen’s-RMC
Queen’s University, Kingston, Canada
DATE: Wednesday March 19, 2014, 1-2 pm EST
ABSTRACT: The available evidence suggests that both geosynthetic clay liners (GCLs) and composite liners with a geomembrane (GMB) over a clay liner have performed extremely well at controlling leakage in field applications for a couple of decades. However there have also been some problems reported and recent research has allowed us to have a much better understanding of the key design and construction factors affecting good and poor performance. This lecture examines some of these issues affecting GCL performance such as the water retention curve of GCLs, subgrade grain size and initial water content, GCL water content and normal stress on the GCL, the effect of daily thermal cycles on hydration, GCL panel shrinkage, and cation exchange. Factors affecting composite liner performance examined include the potential for desiccation of the clay liner under a sustained thermal gradient, GMB/GCL interface transmissivity, wrinkles in the GMB when the ballast layer is placed over the composite liner, and the potential interaction between wrinkles and GCL panel overlaps. Recent insights regarding leakage through composite liners are discussed. Although a number of potential issues with liner performance are discussed, it is concluded that all can be addressed by appropriate design, material selection, construction, and operation.
ABOUT THE SPEAKER: Professor Rowe holds the Canada Research Chair in Geotechnical and Geoenvironmental Engineering at Queen’s University. He is an author of 300 journal papers, 3 books, 18 book chapters, and 290 full conference papers.
