Techniques and Measurements for Flows and Water Levels in a Large Northern Delta

Publication: Critical Transitions in Water and Environmental Resources Management

Abstract

Field work on the Athabasca part of the Peace Athabasca Delta, in Northern Canada, has shown the usefulness of employing new equipment to understand channel hydraulics in remote areas. A differential GPS system was used for accurate surveying work, and an Acoustic Doppler Profiler (ADP) was used to determine flow rates. Channel bank heights for an 81km distance upstream from Lake Athabasca were determined, as were river surface levels at medium discharge in the Athabasca River and its distributary channels. As many as 15 channel sections were surveyed per day with a boat-mounted ADP. For the same daily discharge value, cross-sectional average velocities in the main channel were found to be preserved at about the same value for a remarkably long distance in the final part of the delta, all the way to the lake. Comparison with old data shows a remarkably rapid rate of channel building. Flood magnitudes that cause bankfull flow conditions were found to change by a large factor from the head of the delta to the lake.
