Abstract
The purpose of this report is to provide reconnaissance information on the hydrology and hydraulics of rivers that are crossed by the proposed oil pipe line route from Prudhoe Bay, Alaska, to Edmonton, Alberta, in the sector south of Arctic Red River (i.e., mile 565 to mile 1750, approximately) (Fig. 1). Information for this report was derived from two sources: (1) analysis of maps and air photo mosaics; (2) analysis of streamflow data provided by government agencies. No field reconnaissance was undertaken. Two types of information were given major consideration; the estimation of peak stage in the rivers, and the estimation of maximum bed scour that may result. These are major criteria for design of river crossings. Historical records of streamflow and river behaviour are totally lacking for most of the rivers to be considered in this report. As a result, flow estimates have had to be based on estimates of watershed runoff potential, and onconsiderations derived from river channel appearance. ... the presence of permafrost may modify runoff formation in the watershed, and may affect the behaviour of the river channel during floods. Second, the nival regimen of the rivers produces major spring snowmelt floods - sometimes compounded by river ice jams. Finally, the extensive occurrence of muskeg in watersheds in the southern portion of the Northwest Territories, and in northern Alberta, has a major influence on runoff formation and flood potential in these areas. The report is divided into two systematic sections which discuss, respectively, the hydrology of the study region and the hydraulics of rivers in the study region. Summary tables of hydrological data and hydraulic estimates relevant to the river crossings are given in Appendices 3 and 4. Commentary on individual crossings in Section 4 is restricted to discussion of the sixteen largest rivers.
