Use of Stabilized Stream-Monitoring Sections to Monitor Annual Streamflow on the Alberta Boreal Plain
Streamflow in small forested watersheds on the Boreal Plain of western Canada can be a challenge to monitor due to high variation in flow, shifting channel morphology, aufeis obstructions, shallow channel depth, and debris in the channel. Intensive monitoring in natural channels can overcome some of these problems, but frequent assessment and recalibration of streamflow-stage relationships are necessary. Experience over 8 years indicates that in-channel structures designed to provide a stabilized stream-monitoring section (SSMS) proved beneficial to monitoring efforts during the ice-free season. The SSMS facilitated accurate gauging of the highest and lowest flows encountered during this period, provided a relatively stable foundation against streambank and channel erosion, and allowed passage of fish and the majority of debris and sediments. Functionality of the structures was markedly limited during ice-in conditions, but was improved with the addition of fitted canopies and propane heating systems.
