Abstract

This report is an update of a previous report on channel stability in the Mackenzie Delta, prepared in 1991 as part of the first year of the three-year NOGAP-funded program of IWD Yellowknife dealing with sediment-related aspects of northern hydrocarbon development. The present report supplies the following information: an overview of proprietary literature from industry in the 1970's dealing with channel stability in the outer delta; and a review of the work of the Geological Survey of Canada in 1990-1991 dealing with channel stability at proposed pipeline crossing in the Niglintgak, Taglu and Swimming Point areas; a search of Russian literature dealing with hydrothermal erosion as it might assist channel stability studies in the delta. An overview of the proprietary literature is provided in the first chapter. The next three chapters deal separately, in some detail, with channel stability issues in the three separate areas of Niglintgak Island (Kumak Channel), Taglu Island (Harry and Kuluarpak channels) and Swimming Point (East Channel). A short concluding chapter considers possible further involvement of Inland Water Directorate in this work. All appendices are provided in a second report (Carson, 1993) which is not intended for general circulation, due to the inclusion of proprietary information relaeased to the author for use in this contract. This contains listings of Russian references (App. I), current meter data for the Taglu area (App. II) and borehole data and cross-sectional data found for the Swimming Point area (App. III-VIII). The emphasis given to Swimming Point in the appendices reflects the limited information provided by the GSC open-file for this area compared to the open-file on Niglintgak and Taglu. (Author)
