Network publication summary: Influences of wetlands & forest harvesting and linkages to stream water quality
Leach JA, Buttle JM, Webster KL, Hazlett PW, Jeffries DS. 2020. Travel times for snowmelt-dominated headwater catchments: Influences of wetlands and forest harvesting, and linkages to stream water quality. Hydrological Processes.
Jason Leach and Kara Webster are from Natural Resources Canada, Canadian Forest Service and Jim Buttle is from Trent University. They work together in the Boreal Shield platform of the forWater Network.
Land disturbances, like clear-cut harvesting, can influence the concentrations of dissolved organic carbon (DOC) in stream water, which can have implications for downstream drinking water quality and treatment. Derek Mueller, a Masters student from the University of Alberta, investigated how these disturbances influence DOC dynamics during their journey from the land to the receiving stream in the Montane Cordillera ecozone. The Montane Cordillera is located in western Canada and has a landscape comprised of steeply rolling hillslopes as well as rugged mountains.
The impacts of climate change on our environment can be seen across the globe. From wildfires to floods, natural disturbances have been exacerbated by climate change. High-quality water supplies are at significant risk from these disturbances which could result in deteriorating drinking water quality in many parts of Canada. To manage such risk, the City of Calgary partnered with the forWater Network three years-ago to better understand how to protect their water supply to ensure safe drinking water, even following major landscape disturbances.
"We gain access to research concerning the mobility of nutrients, fire risk and impacts, and linear disturbances around forestry,” said John Jagorinec, Manager, Water Treatment at Calgary.
As one of the young professionals working in the forWater Network, Master’s student Emily Mistick from the University of British Columbia investigated an important question: how does forest management affect drinking water?
Focussing on the Pacific Maritime ecozone, close to her home in Vancouver, Mistick looked specifically at dissolved organic carbon (DOC) in water – which can be challenging and expensive to remove during water treatment. She focused on how DOC fluctuates during storm events in areas with contrasting forest harvest history.
“I’m focusing my research on in-stream DOC measurement in a comparative study between forested and clear cut areas,” said Mistick. “In regions with high rainfall, such as Vancouver, it is known that DOC increases as stream levels rise during storms. The majority of drinking water treatment problems occur during storms, so understanding DOC storm dynamics is very important.”
The Network provides insights into new scientific research for safe, secure drinking water---globally---which starts with resilient forests
