1981, Open-File Report 81-822
This report presents fluvial sediment data collected primarily in response to the eruption of Mount St. Helens. To monitor the sediment transported by streams in the Mount St. Helens area and the particle-size distributions of the sediment, the Water Resources Division of the U.S. Geological Survey initially established 18 fluvial...
Progress report on the effects of surface mining on the surface-water hydrology of selected basins in the Fort Union coal region, North Dakota and Montana
Douglas G. Emerson
1981, Open-File Report 81-678
The purpose of the investigation is to provide a means to assess the impacts on surface-water hydrology due to changes in land use resulting from surface mining of coal in the Fort Union Coal Region, North Dakota and Montana. The objectives of the study are to: (1) Determine premining hydrologic...
Geohydrology and numerical simulation of the alluvium and terrace aquifer along the Beaver-North Canadian River from the Panhandle to Canton Lake, northwestern Oklahoma
Robert E. Davis, Scott C. Christenson
1981, Open-File Report 81-483
A quantitative description of the hydrologic system in alluvium and terrace deposits along the Beaver-North Canadian River in northwestern Oklahoma is needed as an aid for planning and management of the aquifer. A two-dimensional finite-difference model was used to describe the aquifer and to predict the effects of future ground-water...

G. L. Barr, Mario Fernandez
1981, Open-File Report 81-1064
Water-quality data collected between January 1979 and August 1980 at the landfill leachate treatment site in Pinellas County, Fla., are presented. Data include field and laboratory measurements of physical properties, major chemical constituents , nitrogen and phosphorus species, chemical oxygen demand, trace metals, coliform bacteria, taxonomy of macroinvertebrates and phytoplankton,...
Water type and suitability of Oklahoma surface waters for public supply and irrigation; Part 2: Salt Fork Arkansas and Cimarron River basins through 1978
Jerry D. Stoner
1981, Water-Resources Investigations Report 81-39
Water-quality data in the Salt Fork Arkansas and Cimarron River basins within Oklahoma, through 1978, were examined for water type and suitability for public water supply and irrigation use. Of 76 stations with available data, 32 stations or 42 percent were considered to have sufficient data for analysis. The classification...
