Centre for Hydrology / CSHS Principles of Hydrology short course, March 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.

Take on the Drought Game!

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.

Sandford - Saskatchewan needs a water strategy

In his GIWS-sponsored presentation of October 7 2011, Northern Voices, Southern Choices: Water policy lessons for Saskatchewan drawn from leading Canadian and international examples, Bob Sandford, EPCOR Chair of the Canadian Partnership Initiative in support of the UN Water for Life Decade, made a strong case for the need for new thinking on water strategies for Saskatchewan. Major pressures are already being felt as a result of a combination of effects, including climate change, increased water use, and other environmental pressures, and these are likely only to intensify.

The StarPhoenix included a synopsis of the lecture on 8 October 2011, available here, and Bob was interviewed by CBC TV.

Lunchtime Seminar on IP3 Modelling - Friday 7 October

The Centre for Hydrology is pleased to present a hydrology seminar by Muluneh Mekonnen, IP3 Post-Doc, from 12:30 to 1:15pm on Friday 7 October 2011, in AGRI 1E69, entitled IP3's combined top-down and bottom-up modelling approach using MESH and CRHM as complementary modelling platforms

The IP3 (Improving Processes and Parameterization for Prediction in Cold Regions Hydrology) network came to a successful end in September 2011, leaving a legacy of extensive cold regions processes, parameterization and prediction research work.

IP3’s strategic goal was to attain a more comprehensive physical description of cold regions processes and parameterizations, at regional and smaller scales, for improved prediction within hydrological and hydro-meteorological models such as the Cold Regions Hydrological Model (CRHM) and the Community Environmental Hydrology Land-Surface modelling system, known as MESH.

This seminar presents an application of the combined top-down and bottom-up hydrological modelling approach, using MESH and CRHM as complementary modelling platforms, for the South Saskatchewan River Basin (SSRB) and the Upper Assiniboine River Basin (UARB). In addition to cold regions processes, the SSRB and UARB are characterized by the prairie pothole topography that brings in the additional complexity of shrinking and expanding horizontal flow contributing areas.

The seminar will highlight two key points:
1) How to build a model with relatively minimal complexity whose prediction is commensurate with observations, and
2) How to use the Grouped Response Units approach for physically based parameter regionalization.

Feel free to bring your lunch!

CH students' Trans-Canada epic

Centre for Hydrology alumni Nathalie Brunet and Ross Phillips have been taking part in an epic 7000km trans-national adventure, taking them from Vancouver BC to Saint John NB.

Travelling since April, largely by canoe, sometimes by bike (with boats trailered), and even portaging through high mountains on snowshoes, they hope to arrive on the right-hand side of the country sometime over the next few weeks.

The trek was awarded a $25,000 Expedition of the Year grant from the Royal Canadian Geographical Society, and is also receving funding from the RBC Blue Water Project.

They are hoping to use the trip to raise awareness of the importance of Canada’s freshwater resources, and to draw attention to the work done by both the Canadian Heritage River System and the Nature Conservancy of Canada.

Details of the trip are updated regularly on the team's blog / website: they were also interviewed in Ottawa by the CBC.

Seminar - Dr Dennis Lettenmaier: Wednesday 23rd March at 10:30am

Dr Dennis Lettenmaier of the University of Washington will speak on the topic of 'Unanswered questions in predicting the hydrologic impacts of climate change', on Wednesday, March 23, 2011, from 10:30 to 11:30 am, in the Convocation Hall.

Here is an abstract of Dr Lettenmaier's presentation:

From a societal perspective, changes in the land surface water cycle, perhaps aside from sea level rise, represent the most pervasive impacts of climate change. It is well established that increases in concentrations of greenhouse gases, most notably CO2 and CH4, will lead to increases in surface temperatures globally, and these effects are now evidenced in global observations. Furthermore, from first principles, increases in air temperature lead to higher atmospheric moisture, and in turn precipitation. Unfortunately, the implications of these global changes are much more difficult to unravel on a regional level, a problem that is compounded, from the standpoint of land surface hydrology, by the low skill of current generation climate models in representing precipitation. However, even absent these uncertainties, there remain key issues in our ability to represent land surface hydrologic sensitivities to a changing climate. Dr Lettenmaier will discuss three of these areas of uncertainty:
- In hydrologic model predictions of the precipitation and temperature sensitivities of annual runoff
- In the sensitivity of floods to changes in precipitation
- In the coupled interaction of atmospheric circulation and river runoff

PhD Student Presentation by Robert Armstrong: Monday 28th March at 2:30pm

Centre for Hydrology PhD Student Robert Armstrong will present details of his work on 'Spatial Variability of Actual Evaporation in a Prairie Landscape' on Monday 28 March, 2011 at 2:30pm, 144 Kirk Hall.

The following abstract provides an overview of his work;

Actual evaporation has considerable spatial variability that is not captured by point scale estimates from meteorological station data. Physically-based point scale evaporation models were found to provide reasonable estimates of evaporation for temporal scales from several days to seasonal periods but provided poorer estimates for daily and sub-daily periods. Remote sensing was valuable for deriving key variables needed for distributing point scale models for direct estimates over a larger area. A method was developed for distributing net radiation at the field scale which can be used to obtain the spatial variability of evaporation estimates. There was no evidence that spatial covariance between surface variables driving the Granger feedback evaporation model influenced upscaled evaporation estimates which can be attributed to offsetting interactions between model parameters. The variability of point scales estimates obtained from long term hydrological simulations during drought and non-drought periods was further considered across the Canadian Prairie region. The structure of drought was dynamic and there was no consistent spatial pattern of actual evaporation. The variability of evaporation increased as the drought progressed and declined sharply with ensuing wetter conditions.

The results contribute to a better understanding of the effects of spatial associations of key factors on evaporation estimates in a Prairie landscape. The methodology developed for distributing net radiation from assimilated visible and thermal images could potentially be used in regional scale modelling applications for improving evaporation estimates using point scale estimation techniques. The modelling algorithms applied to derive point estimates of evaporation from surface reference data may be useful for operational purposes that require estimates of evaporation (e.g. agriculture, hydrology, ecology, etc.).

Ross Phillips' MSc Thesis Accepted

MSc student Ross Phillips of the Centre for Hydrology, supervised by Prof John Pomeroy and Dr Chris Spence, has received approval for his Master's thesis on 'Connectivity and runoff dynamics in heterogeneous drainage basins'.

Ross's thesis was based largely on fieldwork in the Baker Creek research basin, in the Northwest Territories, and contributed to the findings of the IP3 network.

U of S / CSHS Kananaskis short course, February 2011

The University of Saskatchewan and the Canadian Society for Hydrological Sciences is offering an intensive course on the physical principles of hydrology with particular relevance to Canadian conditions.

Factors governing hydrological processes in Canadian landscapes will be discussed including precipitation, interception, snow accumulation, snowmelt, evaporation, infiltration, groundwater movement and streamflow. These processes will be framed within the context of distinctly Canadian landscape features such as glaciers, peatlands and seasonally frozen ground. State of the art statistical analyses will be presented. Students will be exposed to an overview of each subject, with recent scientific findings and new cutting edge theories, tools and techniques. They will complete numerical and essay assignments to develop skills in problem solving and in synthesizing complex hydrological concepts. Field examinations in nearby environments and research basins will enhance the learning experience. 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.

The course will take place at the University of Calgary Biogeoscience Institute’s Barrier Lake Station in the Kananaskis Valley from February 28 – March 11, 2011. The course will focus on classroom instruction, but will take advantage of the proximity to the Marmot Creek Research Basin to expose students to current field instrumentation and measurement techniques. Each day will start with lectures on the primary subject, and include time to work on assigned exercises. Certain days will include a field work component to examine the processes and measurement techniques relevant to the lectures.

The course is intended for hydrology and water resources graduate students and early to mid-level 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. In 2010, participants were from several universities and employers such as Northwest Hydraulic Consultants, Syncrude, Ducks Unlimited, Brookfield Power, Knight Piesold, AMEC, and Alberta Environment. Participants came from across Canada and the United States.

Course capacity is 30 students. Registration ends February 7, 2011. This physical science course is quantitative in nature and so a firm foundation in calculus and physics at the first year university level and some undergraduate hydrology or hydraulics training is required. Registration and course information can be found here:

If you have further questions, please contact Dr Christopher Spence or Dr John Pomeroy. If interested in receiving academic credit for your participation, please contact Dr Pomeroy. Arrangements have been made for people not currently enrolled in a university program to receive academic credit.

Hydrology course establishes Bow Valley as national centre

By Lynn Martel, Rocky Mountain Outlook, Canmore, AB
March 11, 2010

Students and professionals converged in Kananaskis Country last week to participate in an intensive course on the physical principles of hydrology – the first of its kind in four decades.

Hydrology is the scientific study of the properties, distribution and circulation of water on earth – on the surface, below ground and in the atmosphere.

Taking place at the University of Calgary’s Biogeoscience Institute Barrier Lake Station, the course was hosted by the University of Saskatchewan’s Centre for Hydrology in partnership with the Canadian Society for Hydrological Sciences.

Running March 2-11, the for-credit course drew 40 grad students from the universities of Lethbridge, Regina, Saskatchewan, Manitoba and B.C.’s Simon Fraser, as well as professionals working as environmental assessment specialists, design engineers, environmental technicians, hydrometric technicians, water resource managers, streamflow forecasters and hydrogeologists with employers including Ducks Unlimited, Alberta Environment, Environment Canada and Syncrude.

The jam-packed agenda included full-day classroom sessions covering topics such as the fundamentals and physical principles of hydrology, precipitation and snow hydrology, the hydrology of glaciers, wetlands and groundwater, interception and evapotranspiration, infiltration and soil water, river networks, river hydraulics and ice.

Canadian Water Security – How Science Can Help

Canada has vast reserves of water – yet only 7% of the world’s renewable supply. Water is of critical economic and strategic importance—a resource, a commodity and an essential element in health, agriculture, energy, urban, commercial and industrial development. What is happening to our water resources? What have we learned about changing water conditions across Canada over the last few years—and what questions remain? The Canadian Foundation for Climate and Atmospheric Sciences and Environment Canada invite you to find out.

Since 2000, the Foundation has invested $14.4 million in water related research. The workshop will look at what has emerged from this work and its relevance to safety, security, ecosystems, health and economic development. The Symposium will provide a forum on water security for policy and decision makers, in cooperation with researchers.

Experts explore future of Columbia Basin glaciers

from Revelstoke Times Review
A distinguished panel of glacier scientists was in Golden on Feb. 1 week to present information about the state of water reserves in the Columbia Basin, and to discuss the impacts of shrinking water supply.
Kindy Gosal, Director of Water and Environment for Columbia Basin Trust, said the evening was intended to be an information session for the citizens of the area about glacial recession.
“I think it’s important information to fill in the knowledge gap that people have in this basin about what’s going to happen for the future of water supply in the face of climate change and the recession of our glaciers,” said Gosal.
“The reason we need this information is because those glaciers are our banks and reserves of water. And really, we don’t have a good idea what’s happened to those bank accounts of water and what the future impacts might be as those bank accounts become depleted, or how fast we’re depleting their funds.”
Speaking at the event, Brian Menounos, from University of Northern British Columbia, commented on the potential political ramifications of this research. Part of this involves striking a balance between the electricity and water needs of the people in the Columbia Basin, southern British Columbia, and exports to the United States.
“One of the reasons we are studying these glaciers – and this is also why BC Hydro finds this interesting – people are going to consider the renegotiation of the Columbia Basin Treaty. When it was actually first set, at the turn of the last century, people assumed the glaciers were at their extent, that climate was more or less stable. We know that is not the case now. So we have to have a better understanding of how those glaciers have changed and how surface flows have changed.”

Whatcha gonna do when the well runs dry?

courtesy The Western Producer

What are we going to do when our new well runs dry? Dig a deeper one. What are we going to do when that one runs dry? Drill deeper again and ask why the wells keep running dry.
The prairie moisture cycle has been disrupted. Nobody disputes that point. But how badly is it disrupted and can it be fixed? Nobody knows, says John Pomeroy, director at the Centre for Hydrology at the University of Saskatchewan. Prairie people know they have to go progressively deeper with their wells and as they do, the water is often lower quality than their previous well. “Most shallow surface aquifers once had very good quality water, but very little storage capacity,” said Pomeroy. Small storage limits the ability to recharge and available water is used quickly.
“These shallow aquifers are connected to the surface so they experience the same rain and drought cycles we experience. They get their water from the moisture cycle, which goes up and down, wet and dry.”
As the Prairies required more water for irrigation, livestock and municipal purposes, shallow wells ran dry and were abandoned in favour of deeper wells.
“There’s much more water underground than on the surface or in the shallow aquifers. Nobody knows how much,” Pomeroy said. “But the flow rate in the deep aquifers is extremely slow and it’s mostly very poor quality. There are a few areas with high quality deep water, such as the Assiniboine Delta Aquifer, but most deep water isn’t suitable for agriculture or people. A lot of that water was laid down in pre-glacial times, so it’s old. The older it is, the more dissolved solids it has. It can’t be used for anything.”
Pomeroy said it’s easy to see how shallow wells and their high quality water were pumped dry. The water was needed. But other land management factors affect the situation.
Recharging ground water on the Prairies is different from other places, Pomeroy said. Because these shallow aquifers are small, they recharge quickly from potholes and sloughs. Conversely, they also respond quick- ly to drought or having their recharge sources cut off. “Recharge absolutely depends on sloughs and potholes. You need water standing for a period of time to force it through that thick till layer. Sloughs are mainly filled by snow- melt runoff. Snow is the primary source of water for our prairie water tables. Summer rainfall that runs into the sloughs generally evaporates before it has a chance to recharge the water table.”
Pomeroy said a cool rainy summer will recharge some of the water tables but with 70 percent of prairie sloughs and potholes now drained, every remaining acre of surface water is vital. “Every time we drain another pot- hole, we lose one more source of snowmelt water for our shallow aquifers and recharge for those shal- lower wells. There’s another problem with the remaining sloughs. We’re not putting as much snowmelt runoff into those sloughs as we did 20 years ago.”
Farmers and researchers agree that water is the limiting factor on all types of agricultural production on the Prairies. With a limited amount of water most years, the industry has geared itself to maximum use of that precious resource.

Sound waves used to study snow

By Anne-Marie Hickey, The StarPhoenix, Saskatoon, SK
November 9, 2009

A University of Saskatchewan graduate student has discovered how to use sound waves to determine the water content of snow -- a finding that could help scientists better predict floods and droughts and shed light on climate change.

"Nicholas Kinar is the only person who has been able to figure out how to use sound waves to measure the amount of water in snow," said his supervisor John Pomeroy, Canada Research chair in Water Resources and Climate Change and director of the U of- Centre for Hydrology.

"This will allow people to put improved water management systems in place and offer an early warning for water irrigation supply," said Pomeroy, noting that 80 per cent of the water in Saskatchewan lakes and rivers comes from melted snow.

Going North to Help Gauge Global Water Supply

By Lisa Johnson, For The StarPhoenix, Saskatoon, SK

In the Sheep Creek Basin in Ivvavik National Park, in Canada’s far northwest corner, Stacey Dumanski took full advantage of the amazing 24-hour sunlight this summer to do fieldwork that could help improve global water prediction.

“We are entering a global water crisis, and given rapid climate change and resource development in the North, this work is urgent,” says the fourth-year University of Saskatchewan student.

Water shortages due to climate change could seriously affect Canadians and people all over the world. Dumanski’s research in the remote creek basin will help policy makers better understand water resources in cold regions and predict the global water supply.

In the News: Water Monitoring Network Flows

By Mari-Louise Rowley - Rocky Mountain Outlook

Plans for an integrated hydrometeorological observation and prediction network focused on western Canada's watersheds moved closer to reality as more than 80 delegates attended an international conference at the Radisson Hotel and Conference Centre in Canmore earlier this week.

Running Dec. 8-10, the Improving Water Security Through Integrated Observation and Prediction Networks conference drew top glaciologists, hydrologists and utility and government representatives from the U.S., France and across Canada.
"We're all drinking from the same tap - the tap being the Canadian Rockies," said John Pomeroy, University of Saskatchewan-based Canadian research chair in water resources and climate change. "Our water doesn't stop in western Canada."
Water that originates in the Rockies, from North America's hydrological apex at Mount Snow Dome on the Columbia Icefields, eventually flows to three oceans, the Atlantic, the Pacific and the Arctic, while water from Bow Lake, the headwaters of the Bow River, flows through Calgary and southern Alberta to eventually feed the South Saskatchewan River.
And the issues that are affecting the flows of fresh water all over the world - pollution threats from industry, overuse due to population growth and decreased flows due to the impacts of climate change - are equally pressing in western Canada, Pomeroy said. As such, establishing a network dedicated to collecting data, conducting research, and predicting future flows is an important undertaking, but a restricted one given the work currently underway.
