Prairie Hydrological Modelling Webinar, Monday November 17th

Prof. John Pomeroy will be giving a webinar on The Impact of Wetland Drainage on the Hydrology of a Northern Prairie Watershed to the Association of State Wetland Managers on Monday November 17th at 2 pm Saskatchewan time (1 pm Mountain time).

The talk will detail CH research at Smith Creek, with respect to the hydrological implications of its changing climate and the implications of wetland drainage, as investigated through hydrological model simulations.

If you would like to know more about this research, the webinar will be available at this link.  Thanks are due to co-authors Stacey Dumanski, Logan Fang, Kevin Shook, Cherie Westbrook and Xulin Guo.

Abstract: The Prairie Hydrological Model simulates blowing snow redistribution, snowmelt, infiltration to frozen soils and the fill and spill of networks of prairie wetlands.  The model was used to simulate the hydrology of Smith Creek, Saskatchewan, Canada with various wetland extent scenarios.  This model simulation exercise shows that prairie wetland drainage can increase annual and peak daily flows substantially, and that notable increases to estimates of the annual volume and peak daily flow of the flood of record have derived from wetland drainage to date and will proceed with further wetland drainage.

The Nature of Things features CH research

CBC’s documentary program The Nature of Things has produced an episode called Chasing Snowflakes, which features The Centre for Hydrology’s research in the Canadian Rockies: it will air on Thursday, Nov. 13th at 8pm on CBC TV local channels.

More information is available on the epoisode’s web-page, here.

Pomeroy to Chair and Present at UN Climate Change and Water Workshop

Professor John Pomeroy has been invited to chair sessions and present at the UNESCO International Workshop on Climate Change Impacts on Snow, Glacier and Water Resources: Multidisciplinary Network for Adaptation Strategies (www) to be held 6-7 November at the International Centre for Water Resources and Global Change in Koblenz, Germany.

Pomeroy’s talk will be on Alpine snow hydrology and the International Network for Alpine Research Catchment Hydrology – water towers for the world. The talk will outline the activities of a new collaborative research network led by Pomeroy, INARCH – the International Network for Alpine Research Catchment Hydrology.

Research contributing to INARCH is taking place in the Americas, Europe and Asia and is demonstrating the tremendous sensitivity of alpine water supplies to climate warming. By better observations and modelling of mountain snowpacks and their melt, INARCH hopes to identify the most vulnerable mountain snowpacks and the implications of their loss for downstream water supplies.

The Workshop will inform UN climate change policy and the International Hydrological Programme activities relating to sustainable water supply. The UN’s overall aim for the Workshop is to connect scientific research, policy development and action, and identify recommendations to enhance the interface between science and policy to develop sustainable adaptation strategies.

U of S Centre for Hydrology contribution to Global Chorus

The University of Saskatchewan Centre for Hydrology has contributed two chapters to Global Chorus, a collection of 365 perspectives on the environmental future of the planet.

John Pomeroy, director and Bob Sandford, fellow have written contributions on climate change and hydrology that are frank assessments of the challenges imposed by excessive greenhouse gases and the global water crisis from the perspective of research in western Canada and elsewhere.

Contributors to the book are from around the world and include Nelson Mandela, Stephen Hawking, the Dalai Lama, Archbishop Desmond Tutu, Mikhail Gorbachev, Jane Goodall, John Ralston Saul, Farley Mowat and many others. Global Chorus is being published this month by Rocky Mountain Books: more details are available at

Pomeroy to Lecture on 2013 Floods at U of C

Professor John Pomeroy has been invited to make a presentation titled The Mountain Hydrology behind the Alberta Flood of 2013 as part of the University of Calgary’s Energy and Environmental Systems Specialization Seminar Series.

The talk, which is free and open to the public, will take place at 3pm on Monday 6th October in EEEL 210 (Energy. Environment. Experiential Learning, 750 Campus Drive).

R Lunch Wednesday 15th October 11:30am

This month’s R Lunch will take place on Wednesday October 15th at 11:30am in Physics 126.

It will be presented by Phillip Harder, who is a Ph.D. candidate at the Centre for Hydrology. The title of his presentation is: How reproducible is your research?: Principles and R examples

R Lunch, Wednesday 17 September

You are invited to the next R Lunch, an occasional series showing how R is used in the university.

It will be on Wednesday September 17 at 12:00 noon in Arts 213.

This session will be presented by Dr. Nicole Nadorozny, who is currently a Postdoctoral Fellow in the Dept. of Computer Science.
Her presentation touches on R, GIS and hydrology, so will be of interest to many people.

WaterToolbox Tool – A River Health Assessment Tool

Presentation Summary:
A scientifically-based statistical protocol for conducting baseline assessments in river indicators was developed for Saskatchewan Watersheds using R open source software. The empirical assessments quantify the state of rivers and indicate if conditions have stayed the same, improved or deteriorated given time series available.

A WaterToolbox tool for ESRI ArcGIS was developed to implement the statistical framework for system application. The tool uses monitoring data from Provincial and Federal sources accessed via a file geodatabase and runs the R scripts through a Python interface within the ArcGIS platform.

Yale Magazine Features CH Research

Author Ed Struzik has written an article on the loss of snow and glaciers in the Canadian Rockies and how this threatens water resources in Western Canada. The article highlights some research results from the Centre for Hydrology and allied researchers in western Canada. It is available online here.
