Online Research Seminars – Hydrology

The second Hydrology session will take place this Friday, June 26, 2020 at 2 pm Eastern Time. The series will continue most Fridays this summer, with the next series of talks scheduled for Friday, July 3rd. A full schedule of the summer series will be shared soon. We invite you to follow the series on our Facebook, Twitter and/or LinkedIn pages for the latest information.

This week’s research talks include:

“Field Investigation of Snowmelt Partitioning in Frozen Prairie Soils”
Speaker: Sama Khawaja
Affiliation: University of Calgary (student talk)
Time: 2 pm – 2:15 pm EDT
Session: Hydrological processes in frozen soils
Highlights: A tracer study was conducted on a prairie grassland to study the partitioning of snowmelt between infiltration and runoff on partially frozen ground. Results highlight the role of preferential flow in understanding infiltration-runoff dynamics and how water moves to topographic depressions.

“Efficient Modelling of Seasonal Soil Freeze/Thaw”
Speaker: Élise Devoie
Affiliation: University of Waterloo (student talk)
Time: 2:20 pm – 2:35 pm EDT
Session: Hydrological processes in frozen soils
Highlights: An efficient interface model of soil freeze-thaw is extended to accurately represent seasonal freeze-thaw with promising applications in sensitivity analyses, and hydrologic modelling.

“An Evaluation of Ground-Freezing Methods in the Zone of Discontinuous Permafrost, Northwest Territories”
Speaker: Ela Mastej
Affiliation: Wilfrid Laurier University
Time: 2:40 pm – 2:55 pm EDT
Session: Permafrost Hydrology and Hydrogeology: Interactions, Innovations, and Challenges
Highlights: Ela has evaluated the performance of various ground cooling systems in the the subarctic wetland that are projected to stabilize ground temperatures and support permafrost. She also evaluated the role of snow on the ground thermal regime and on the performance of one of the thermosyphon design.

“Measurements and Preliminary Results from the Storms and Precipitation Across the continental Divide Experiment (SPADE)”
Speaker: Hilary Smith
Affiliation: University of Northern British Columbia/ Université du Québec à Montréal
Time: 3 pm – 3:15 pm EDT
Session: Recent advances in quantifying hydrometeorological conditions in cold regions
Highlights: The Storms and Precipitation Across the continental Divide Experiment (SPADE) took place from 24 April – 26 June 2019, where researchers studied precipitation events on either side of the continental divide in the southern Canadian Rockies using a combination of meteorological instruments and manual observations. This presentation will provide a brief description of the field campaign and discuss the initial results.

“Regional Variability in Stream Dissolved Organic Matter Characteristics across Forested Regions of Canada, and its Implications for Drinking Water Treatability”
Speaker: David Olefeldt
Affiliation: University of Alberta
Time: 3:20 pm – 3:35 pm EDT
Session: Hydrologic response to forest change
Highlights: David will be presenting a study of variability in dissolved organic matter from streams across Canada. Large variability between regions in stream DOM chemical composition is linked to characteristics of ecoregions. Quantity, not quality of DOM is the best predictor of disinfectant byproduct production potential.
