From abstract: Suspended-sediment and bedload-transport rates for the Tanana River near Fairbanks, Alaska, can be related to water discharge, and annual sediment loads can be computed using these relations.

From introduction: This report contains data on physiographic and climatic characteristics of the Kobuk River basin, as well as stream channel hydraulic properties, seasonal quantity and quality of surface waters, floods, channel erosion, and benthic invertebrates. The data show the magnitude and ranges of stream discharge, width, depth, and velocity, of flow that can be expected in late winter and summer periods, and indicate flood and erosion hazards in the basin.

From introduction: Data adequate to describe general flow conditions have been collected on most major streams in the Anchorage area, but comparable water-quality data needed to determine the effect of urbanization on the streams are scarce. Thus, in 1980 the U.S. Geological Survey, in cooperation with the Municipality of Anchorage, began a study of the effects of urban runoff on stream-water quality. A premise of the study was that urbanization does have an effect on the quality of surface runoff. The primary purpose of the study was to determine differences in water-quality characteristics between streams that drain natural and urban areas in Anchorage.

From abstract: Suspended-sediment and bedload-transport rates for the Tanana River near Fairbanks can be related to water discharge and annual sediment loads can be computed using these relations. For a site at Fairbanks the annual loads in 1982 were 26.1 million tons of suspended sediment and 227,000 metric tons of bedload. Data collected at five other sites within a 40-kilometer reach of the river indicate very similar suspended-sediment-transport relations but bedload-transport relations varied from site to site. For all sites bedload is on the order of 1 percent of suspended-sediment load.

From introduction: Coal can absorb trace metals during coalification, then release them into the environment when the coals are weathered and exposed to erosion. Trace metals in materials associated with the coals also can be released as these materials are disturbed during mining. The purpose of this study was to determine the concentration, distribution, and possible sources of selected trace metals in surface water and stream sediments of the Healy Creek and Lignite Creek basins in the Nenana coal field, Alaska.

From introduction: This report is a product of a Geological Survey program, under way since the early 1970's, to study environmental conditions in selected frontier areas of Alaska...The purpose of this report is to present reconnaissance-level data on the surface-water resources of the Togiak River basin. These data include measurements and observations of streamflow conditions during late summer and late winter periods, stream-channel characteristics, evidence of past flooding and erosion, water quality, and benthic invertebrate populations.
