Proceedings of workshop XXVIII on the Borah Peak, Idaho earthquake

A large earthquake leaves clues of its nature that can be interpreted only by a diverse group of scientists. We cannot hope to form a coherent picture of the Borah Peak shock, a rare Great Basin event, without listening to each other and reflecting on the historical and geological record of its antecedents. At a workshop held less than a year after the Borah Peak mainshock we shared our observations, exchanged ideas, and revisited the spectacular landforms at the earthquake site. In the forty reports of this volume we present our findings, a wealth of preliminary, but interdisciplinary research.

Supplemental arsenic data for selected streams in the Missouri River basin, Montana, 1987

Geothermal waters within Yellowstone National Park contribute arsenic to the Madison River. Concentrations ranging from 200 to 300 micrograms per liter in the Madison River near the park boundary are diluted downstream by tributary inflows to the Madison and Missouri Rivers. However, significant amount of arsenic are present in the water of the Missouri River as it enter Fort Peck Lake. A monitoring network of 24 stations was operated during 1985 and 1986 in the upper Missouri River basin to measure arsenic concentrations and arsenic discharges. Additional monitoring at nine stations was conducted during March to July 1987 to supplement the data base. This report presents data acquired from the 1987 monitoring period. (USGS)

Surface-water and water-quality data from selected streams and treated waters in the Greensboro Area, North Carolina, 1986-87

Water and bottom-sediment samples were collected from April 1986 to September 1987 at 19 sites in Guilford County and the City of Greensboro, North Carolina. Sampling locations included 13 stream sites, two lakes that supply City of Greensboro drinking water, two City of Greensboro finished drinking-water filtration plants, and two municipal wastewater plants where effluents were sampled prior to outfall into the receiving streams. Water sampling consisted of six routine samplings during various stages of steady flow at all sites, and rainfall-event sampling during two storms at six sites. Bottom-sediment samples were collected at three sites during two routine samplings. Samples were analyzed for trace-element, major ion, and nutrient concentrations, as well as general water-quality indicators, such as pH, dissolved oxygen, and specific conductivity. Concentrations of acid and base/neutral extractable, volatile organic compounds, and organochlorine and organophosphorus constituents were also determined. Chromatographs from organic analyses were submitted to computerized library searches, the results of which are included in this report. Results from all analyses are presented in tabular form in the appendices.

Radionuclides, stable isotopes, inorganic constituents, and organic compounds in water from selected wells and springs from the southern boundary of the Idaho National Engineering Laboratory to the Hagerman area, Idaho, 1993

The U.S. Geological Survey and the Idaho Department of Water Resources, in response to a request from the U.S. Department of Energy, sampled 19 sites as part of a long-term project to monitor water quality of the Snake River Plain aquifer from the southern boundary of the Idaho National Engineering Laboratory to the Hagerman area. Water samples were collected and analyzed for selected radionuclides, stable isotopes, inorganic constituents, and organic compounds. The samples were collected from seven irrigation wells, four domestic wells, two springs, one stock well, three dairy wells, one observation well, and one commercial well. Two quality assurance samples also were collected and analyzed. None of the radionuclides, inorganic constituents, or organic compounds exceeded the established maximum contaminant levels for drinking water. Most of the radionuclide and inorganic constituent concen- trations exceeded their respective laboratory reporting levels. All samples analyzed for surfactants and dissolved organic carbon had concentrations that exceeded their reporting level. Ethylbenzene concentrations exceeded the reporting level in one water sample.

Estimated water use, by county, in North Carolina, 1990

Data on water use in North Carolina were compiled for 1990 as part of a cooperative agreement between the U.S. Geological Survey and the Division of Water Resources of the North Carolina Department of Environment, Health, and Natural Resources. Data were compiled from a number of Federal, State, and private sources for the offstream water-use categories of public supply, domestic, commercial, industrial, mining, livestock, irrigation, and thermoelectric-power generation. Data also were collected for instream use from hydroelectric facilities. Total estimated offstream water use in the State for 1990 was about 8,940 million gallons per day. About 95 percent of the water withdrawn was from surface-water sources. Thermoelectric-power generation accounted for about 81 percent of all withdrawals. Data for instream water use for hydroelectric-power generation also were compiled. This instream water use totaled about 66,900 million gallons per day. eAch water-use category is summarized in this report by county and source of water supply.

Streamflow and sediment data collected to determine the effects of a controlled flood in March and April 1996 on the Colorado River between Lees Ferry and Diamond Creek, Arizona

An 8-day period of planned release of water at 1,275 cubic meters per second from Glen Canyon Dam in March and April 1996 provided an opportunity to collect data on river stage, streamflow, water chemistry, and sediment transport at discharges above powerplant releases. The U.S. Geological Survey collected data at five streamflow-gaging stations on the mainstem of the Colorado River and four on tributaries during the controlled flood. River-stage data were collected at an additional 29 locations, and suspended-sediment data were collected at 4 of the 5 mainstem streamflow-gaging stations. In addition, measurements of reach-average flow velocity were made using a dye tracer, and water-surface slope was measured in reaches adjacent to three of the streamflow-gaging stations. Sand-storage changes caused by the controlled flood were documented by measuring bed elevation of the channel at cross sections before and after the controlled releases at the network of 120 monumented locations. This report presents selected data in tabular and graphical form. The data presented in the report are available in electronic form.

User's guide to Model Viewer, a program for three-dimensional visualization of ground-water model results

Model Viewer is a computer program that displays the results of three-dimensional groundwater models. Scalar data (such as hydraulic head or solute concentration) may be displayed as a solid or a set of isosurfaces, using a red-to-blue color spectrum to represent a range of scalar values. Vector data (such as velocity or specific discharge) are represented by lines oriented to the vector direction and scaled to the vector magnitude. Model Viewer can also display pathlines, cells or nodes that represent model features such as streams and wells, and auxiliary graphic objects such as grid lines and coordinate axes. Users may crop the model grid in different orientations to examine the interior structure of the data. For transient simulations, Model Viewer can animate the time evolution of the simulated quantities. The current version (1.0) of Model Viewer runs on Microsoft Windows 95, 98, NT and 2000 operating systems, and supports the following models: MODFLOW-2000, MODFLOW-2000 with the Ground-Water Transport Process, MODFLOW-96, MOC3D (Version 3.5), MODPATH, MT3DMS, and SUTRA (Version 2D3D.1). Model Viewer is designed to directly read input and output files from these models, thus minimizing the need for additional postprocessing. This report provides an overview of Model Viewer. Complete instructions on how to use the software are provided in the on-line help pages.
