A preliminary appraisal of the effects of agriculture on stream quality in southwest Georgia
Dean B. Radtke, James B. McConnell, William P. Carey
1980, Open-File Report 80-771
Water—quality and suspended—sediment samples were collected in two basins in southwest Georgia to determine whether water—quality problems have resulted from agricultural practices. Samples were collected monthly and during periods of storm runoff from December 1976 through July 1978. Concentrations of chemical constituents relevant to agricultural practices were found to be...
Field data describing the movement and storage of sediment in the East Fork River, Wyoming: Part II, Bed elevations, 1979
Robert H. Meade, Robert M. Myrick, William W. Emmett
1980, Open-File Report 80-1190
At 39 cross sections in a 3.3-kilometer reach of East Fork River Wyo., bed elevations were measured daily during a month-long period that included the peak snowmelt runoff. Elevations were measured at less frequent intervals for a week before and several weeks after peak runoff. Considerable scour and fill was...
Evaluation of planning alternatives for maintaining desirable dissolved-oxygen concentrations in the Willamette River, Oregon
David A. Rickert, F. A. Rinella, W. G. Hines, S. W. McKenzie
1980, Circular 715-K
For nearly half a century the Willamette River in Oregon experienced severe dissolved-oxygen problems related to large loads of organically rich waste waters from industries and municipalities. Since the mid-1950 's dissolved oxygen quality has gradually improved owing to low-flow augmentation, the achievement of basinwide secondary treatment, and the use...
U.S. Geological Survey role in earthquake prediction
David P. Hill
1980, Open-File Report 80-144
Work in the Seismology Branch on the problem of earthquake prediction is based primarily on the recording and analysis of seismic (elastic) waves in the Earth generated either by earthquakes themselves or by artificial sources such as quarry blasts or explosions detonated in drill holes. At the present time this...
