The Centre for Hydrology is co-sponsoring a suite of presentations hosted by the Interpretive Guides’ Association on Thursday, March 1 at the Policeman’s Creek Drop-In Centre in Canmore, AB, entitled Why Cold Matters: The State and Fate of Canada’s Ice and Snow.
The evening will feature presentations by Prof John Pomeroy (Director of the Centre for Hydrology), Bob Sandford (CH associate and chair of the Canadian arm of the UN’s Water for Life Decade), and glaciologist Dr Shawn Marshall (University of Calgary): all three presenters are key members of the Western Watersheds Research Collaborative.
“Canadians love their snow and its beauty, but often see it as something to be only shovelled or skied upon,” says Dr Pomeroy. “But, not only is it one of the most beautiful and physically complex natural phenomena, it is the home of many plants and animals, the food source for many more and the provider of water for the alpine summer and for the rivers that drain the mountains to provide water to the parched prairies.”
The role of snow as a part of the mountain ecosystem, how it interacts with forests and alpine vegetation and how it is sensitive to climate warming comprise just part of the focus of the presentation.
Summarizing the recent findings of two networks of cold regions research funded by the Canadian Foundation for Climate & Atmospheric Science that form the basis of his forthcoming book, Cold Matters: The State and Fate of Canada’s Fresh Water, Mr Sandford will focus on how seemingly small changes in temperature are influencing not just Canada’s climate, but also Canadians’ very identity.
“We are likely the first generation of human beings to accurately measure and fully understand how what we may have once thought were very small relative changes in mean temperature – changes as small as a single degree Celcius – can result in changes in the behaviour of the atmosphere noticeable enough to be reflected in the patterns of the seasons,” Sandford said.
“Because the most pronounced warming is occurring in winter, the most visibly obvious changes are related to the extent and duration of snow pack and snow cover. Snow cover, atmospheric circulation and temperature are inter-dependent and relate to one another as feedbacks. Water and temperature define climate. Climate defines ecosystems; and ecosystems define us.”
“In the absence of snow we would be different people living in a different world. It appears that, in the context of where and how we live in Canada, cold really does matter.”
Dr Marshall will discuss the latest research findings related to the effects of contemporary climatic trends on the extent and influence of glaciers in Canada’s western mountains and abroad, while Pomeroy will share the findings of his own research.
“The water security of Western Canada is predicated on the preservation of the natural flows and storage of mountain snow, ice and water,” Pomeroy said. “This controls our natural ecosystems and our ability to provide communities, food and energy throughout Western Canada. We risk everything by losing it, and so must conserve our mountain cold environments.”
Why Cold Matters: The State and Fate of Canada’s Ice and Snow takes place on Thursday, March 1 at the Policeman’s Creek Drop-In Centre. Doors open at 7 with the presentation beginning at 7:30. Admission is free.

The 11th annual Western Canada CGU Hydrology Section student conference will be held at the University of Saskatchewan on February 11th, 2012.
Abstracts (max 250 words) are invited for oral presentations by CGU members, by January 25th, 2012.

The Centre for Hydrology and Canadian Society for Hydrological Sciences will again be holding their popular short course in Physical Principles of Hydrology in the Kananaskis Valley, Alberta, from March 1-12, 2012.
The course is intended for hydrology and water resources graduate students and early to midlevel career water resource engineers, hydrologists, aquatic ecologists and technologists from Canada who are either working directly in hydrology and water resources or are looking to broaden their understanding of hydrological systems and processes.
Factors governing hydrological processes within the context of distinctly Canadian landscape features will be discussed. Students will be exposed to an overview of each subject, with recent scientific findings and new cutting edge theories, tools and techniques, through a combination of classroom sessions at the University of Calgary’s Biogeoscience Institute’s Barrier Lake Station, and fieldwork at the Marmot Creek Research Basin.
Students will emerge from the course with a deeper understanding of physical hydrological processes and how they interact to produce catchment water budgets and streamflow response, together with state-of-the-art field instrumentation and measurement techniques.
More information is available here, or from Dr Chris Spence or Dr John Pomeroy

Andrew Ireson, Assistant Professor in Subsurface Hydrology with the School of Environment and Sustainability and the Global Institute for Water Security, is keen to hear from grad. students who may be interested in participating in an Invitational Drought Tournament.
This is a game in which students from U of Alberta, U of Regina and U of Saskatchewan will form multi-disciplinary teams, consisting of approximately five players. Having chosen their initial conditions or ‘preparedness strategies’, teams will be guided through a simulated multi-year drought scenario of unknown length and severity, throughout which they will work collaboratively to discuss and select adaptation options that should help them better prepare for, adapt to, respond to, and recover from the drought’s impacts. The chosen strategies should maximize economic benefits and reduce social and ecological stress. More details are given here, in a description of a similar tournament held last year.
The game will take place in late February / early March of 2012. At this stage, Andrew is looking to find out who is interested in participating. This is all about decision-making under pressure, with finite resources, focusing on minimizing environmental impacts of droughts, which are one of the most expensive, devastating natural disasters in the Canadian prairies (billion dollar impacts). It should also be great fun – it’s a game after all. If you think you would like to take part, or if you have any questions or comments please get in touch with Andrew.

The Global Institute for Water Security is pleased to present a lecture by Bob Sandford, EPCOR Chair of the Canadian Partnership Initiative in support of the UN Water for Life Decade, on October 7, 2011.
The lecture, entitled Northern Voices, Southern Choices: Water policy lessons for Saskatchewan drawn from leading Canadian and international examples will begin at 1:45 pm in Room 144 Kirk Hall.
The presentation will be followed by a panel discussion featuring Howard Wheater (Global Institute for Water Security and SENS), Patricia Gober (Johnson-Shoyama Graduate School of Public Policy), and John Pomeroy (Centre for Hydrology and Department of Geography and Planning). More details here.
