Slaughter, C.W.; Collins, C.M. Sediment load and channel characteristics in subarctic upland catchments
Sediment load in low-order streams of the unglaciated Yukon-Tanana Uplands of central Alaska may be related to drainage basin characteristics and to stream channel morphology. This has been investigated by analysis of selected physical, hydrological and water quality data for the 104 km2 Caribou-Poker Creeks Research Watershed, located at 65°09'N, 147°30'W in a region of roiling to steep uplands and discontinuous permafrost. Channel morphology data are available for first-, second- and third-order streams. Sediment load for selected points was determined over 45 weeks during summers of 1978 and 1979. Consistent differences in sediment yield, hydrologic regime and channel morphology have been determined between permafrost and non-permafrost drainages.
