Professor David Male 1939-2020

The University of Saskatchewan hydrological community has lost one of the developers of hydrology at USask. Dr. David Male, a professor of Mechanical Engineering at USask, was one of the pioneers of the study of snow with seminal studies of snowmelt energetics, blowing snow transport, snow sublimation, infiltration into frozen soils and the development of hydrological models. Together with Professor Don Gray he edited and wrote parts of the 776 page Handbook of Snow: Principles, Processes, Management and Use in 1980 – still the most comprehensive book on snow and a key foundational book https://blackburnpress.stores.yahoo.net/haofsnprprma.html.

Professor Male contributed a strong physics-based approach to the study of cold regions hydrology and emphasized the need for results to be based on firm physical principles and advanced experimentation and observations in outdoor environments. He was amongst the first to identify the major problems with solving the “energy equation” for snowmelt and then to offer solutions using coupled energy and mass budgets, dimensional analysis, turbulent transfer and radiative transfer theory. Working with Raoul Granger, Don Gray and Tom Brown, he deployed advanced instrumentation controlled by computers for snowmelt studies at remote sites in the early 1970s when this presented considerable technical challenges. He was active in all aspects of snow science from leading advanced field studies at the USask Division of Hydrology’s Bad Lake research site, to developing analytical solutions for mathematical problems, writing computer models, training students, and writing scientific papers and books.

Professor Male was a lead faculty member in the Division of Hydrology and his work at the University of Saskatchewan laid the foundation for USask’s development of cold regions hydrology and water security into current areas of institutional strength. He also made important contributions to the work of Environment Canada, National Research Council of Canada, American Geophysical Union, US Office of Hydrology (National Weather Service), Atomic Energy of Canada Limited, Saskatchewan Environment, Alberta Environment and other groups. Dr. Male was an excellent teacher who could explain difficult engineering concepts exceptionally clearly to his students. He will be remembered by his former students and colleagues not only as an exceptionally brilliant scholar who made formidable advances in science, but also as a very nice, warm, supportive and friendly person who welcomed and encouraged many into engineering, science and academia. Professor Male passed away in Saskatoon earlier this month, his full obituary can be found here.

New Article- The Future We Want, The UN We Need

By Robert W. Sandford,
Senior Fellow of the Centre for Hydrology and Global Water Futures Chair at United Nations University

As we reflect on this week and celebrate the United Nations’ rise in the war-ravaged world some 75 years ago, humanity is again being asked to lay the foundation for a new world.

As in 1945, we are asked to envision the world that emerges from a global catastrophe. Similarly, as well, in our post-pandemic world we will need to make not a partial but a full transformation, one in which human self-interest again aligns with planetary realities.

Such a global reset can produce universal benefits in the form of a healthier, more just, safer, kinder and more spirituality connected society.

Postponed- John Pomeroy to discuss the results of the Bow River project in Natural Resources Canada (NRCan) webinar June 3rd

Canada’s Climate Change Adaptation Platform is please to offer:

A Blueprint for Climate Change and Future Flooding: A Case Study of Calgary’s Bow and Elbow River Basins

Presenter: Dr. John Pomeroy

Wednesday, June 3, 2020, 2-3 PM (ET) 

Abstract: While increases in precipitation and temperature have been observed across Canada in the last half-century and are predicted for the future as climate change proceeds, there is still little understanding of how climate change will affect future streamflow and flooding in Canada due to the complexity of meteorological, hydrological, and water management aspects of flooding. This project modelled the historical and future changes in the flow frequencies of the Bow and Elbow river basins above Calgary to better understand how natural . processes and reservoir management contribute to river flow and flood frequency estimates and how they can be expected to change with a changing climate through the 21st C. In this webinar geared toward technical experts, Dr. John Pomeroy will present the case study and methodology for incorporating climate change into flood frequency and water supply estimates, including a blueprint for applying these lessons in river basins across Canada.

Climate change, pollution and urbanization threaten water in Canada

In recent years, the daily news has been flooded with stories of water woes from coast to coast to coast.

There are melting glaciers and ice sheets in northern and western Canada and lead in drinking water in the older neighbourhoods of many cities in Canada. We see toxic blue green algae threatening pets, livestock and drinking water as well as catastrophic floodsdroughts and fires.

In 2018, parts of British Columbia experienced devastating floods, followed by wildfires a couple of months later.

Our water resources are under threat from contamination, land use, urbanization and climate change. If we’re not careful, it may not be clean enough or available when we need it.

The world is ‘losing its cool’ with the loss of snowpacks and glaciers, posing threats to water security

The following was released by the University of Saskatchewan:

MADRID, SPAIN – At the United Nations Climate Change Conference in Madrid, Spain (COP25), University of Saskatchewan (USask) scientists are focusing attention on the world’s changing mountain snowpacks, glaciers, vegetation, and long-term effects that the thaw of snow and ice are having on the world’s freshwater and ocean water.
