The 10 June 2011 edition of Canmore’s Rocky Mountain Outlook newspaper included an overview of the extreme variability in snowpack and melt behaviour observed in Marmot Creek and other sites through the Alberta Rockies this spring: the article is available here.
The same edition also profiled the PUB2011-P3 workshop held in May (here).
Chris Marsh wins prize at CGU
Congratulations to CH MSc student Chris Marsh, who has been awarded the D.M.Gray Award for Best Student Paper in Hydrology at the Canadian Geophysical Union this year, for his paper and talk Implication of mountain shading and topographic scaling on energy for snowmelt.
There was a large number of applicants and the papers and presentations were very strong, so this is a particularly significant feedback to Chris. CH Director Prof John Pomeroy comments “I am sure that Don Gray would be very happy with this”.
The paper is available for download here.

Canmore’s Rocky Mountain Outlook profiles CH ‘Principles of Hydrology’ course
CH / Canadian Rockies Snow & Ice Presentations: 14th April 2011
The Centre for Hydrology’s ‘Canadian Rockies Snow & Ice‘ initiative is partnering with the Western Watersheds Climate Research Collaborative and Interpretive Guides Association to present ‘Storm Warning: Emerging Issues in Water & Climate Science‘.
Presentations will provide a synopsis of recent advancements in glacial research and hydro-climatic science related to the interface between ice, water and the atmosphere, here in the Rockies and around the world.
The Forum will be moderated by Dr Ed Johnson, Director of the University of Calgary’s Biogeoscience Institute, and speakers will include Dr Mike Demuth (head of the Glaciology Division of the Geological Survey of Canada), Jocelyn Hirose (University of Calgary, glaciology), and Bob Sandford (EPCOR Chair in support of the United Nations Water for Life Decade in Canada). More information is available here.
The event will take place in the Canmore Collegiate High School Theatre at 7pm on Thursday, April 14th, 2011.
Global Institute for Water Security Launches
In the course of his presentation entitled Water Security and the Perfect Storm on United Nations World Water Day, March 22nd, Canada Excellence Research Chair Professor Howard Wheater announced the establishment of a new Global Institute for Water Security, to be based at the University of Saskatchewan.
Full details are available here
Water Week presentations now available online
Two hydrology-related presentations from the University of Saskatchewan’s Water Week are now available for online viewing:
Water Security and the Perfect Storm by Professor Howard Wheater, Canada Excellence Research Chair in Water Security
Climate Uncertainty: What it Means for Water Planning and Policy – recent results from Saskatchewan and Arizona by Professor John Pomeroy, Canada Research Chair in Water Resources and Climate Change, and Professor Patricia Gober, Johnson Shoyama Graduate School of Public Policy
Star Phoenix Profiles CH Plans for Flood Research
March 25th – The Saskatoon Star Phoenix published an article highlighting planning by Professors John Pomeroy and Howard Wheater for a major Prairie research project this spring.
With near-record snowpacks persisting later than usual this year throughout much of the West, it’s envisaged that the imminent melt season may well provide a “once-in-a-lifetime” opportunity to observe and document a runoff – and potentially flood – event of the scale currently thought to be likely.
The article is available here.
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.).
