DESIGN AND ANALYSIS OF ROCKFILL DAMS: PAST, PRESENT AND FUTURE Session: Keynote / Conférence Jean-Marie Konrad, Université Laval (Canada) The 2015 R.M. Hardy lecture reviews the evolution of the design practice at Hydro-Quebec for four generations of rockfill dams. Innovative research to advance the practice is presented with particular emphasis on scale effect and particle breakage, internal erosion and contact erosion. Future developments with respect to seismic design are outlined with an emphasis on permanent deformation prediction and in situ testing in rockfill to obtain representative material parameters. Finally, analysis of rockfill dams considering evolving material properties is discussed.
