ABSTRACT

The main points about slope safety preparedness with regards to climate change are: understanding the current situation, downscaling the climate model projections, integrating relative impacts of human activity and mitigating and adapting to potential or existing consequences. Overall changes in hydrology and streamflow are informative for understanding impacts, changes in hydrologic extremes are most relevant for understanding potential changes in debris flow and debris flood activity. In a sense, as mentioned by M. J. Crozier and N. J. Preston, one must understand how landslide conditions develop and evolve with time, in addition to potential impacts from climate change. Developing adaptation practices or technologies to reduce the potential impact of climate change on landslide activity will be a very challenging issue. In Canada, apart from the study of the impacts of warming of permafrost, there has been no real attempt to produce zoning maps which will take climate change into account.
