Conceptual design for the National Water Information System
Melvin D. Edwards, Arthur L. Putnam, Norman E. Hutchison
1986, Open-File Report 86-604
The Water Resources Division of the U.S. Geological Survey began the design and development of a National Water Information System (NWIS) in 1983. The NWIS will replace and integrate the existing data systems of the National Water Data Storage and Retrieval System, National Water Data Exchange, National Water-Use Information Program,...
Data uses and funding for the stream-gaging program in Utah
R.W. Cruff
1986, Open-File Report 86-51
This report documents the results of the first phase of a study of the cost effectiveness of the streamflow-information program in Utah. Data use, funding, and data availability are described for the streamflow stations operated by the U.S. Geological Survey; and a history of the stream-gaging program is given. During...
Hydrogeology and simulation of water flow in strata above the Bearpaw Shale and equivalents of eastern Montana and northeastern Wyoming
W. R. Hotchkiss, J. F. Levings
1986, Water-Resources Investigations Report 85-4281
The Powder River, Bull Mountains, and Williston basins of Montana and Wyoming were investigated to understand the geohydrology and subsurface water flow. Rocks were separated into: Fox Hills-lower Hell Creek aquifer (layer 1), upper Hell Creek confining layer (layer 2), Tullock aquifer (layer 3), Lebo confining layer (layer 4), and...
The SALT NORM : a quantitative chemical-mineralogical characterization of natural waters
Marc W. Bodine Jr., Blair F. Jones
1986, Water-Resources Investigations Report 86-4086
The new computer program SNORM calculates the salt norm from the chemical composition of a natural water. The salt norm is the quantitative ideal equilibrium assemblage that would crystallize if the water evaporated to dryness at 25 C and 1 bar pressure under atmospheric partial pressure of CO2. SNORM proportions...
Evaluation of sampling methods used to estimate irrigation pumpage in Chase, Dundy, and Perkins counties, Nebraska
F.J. Heimes, R. R. Luckey, D.M. Stephens
1986, Water-Resources Investigations Report 86-4092
Combining estimates of applied irrigation water, determined for selected sample sites, with information on irrigated acreage provides one alternative for developing areal estimates of groundwater pumpage for irrigation. The reliability of this approach was evaluated by comparing estimated pumpage with metered pumpage for two years for a three-county area in...
Application of the aerial profiling of terrain system
E.J. Cyran
1986, Open-File Report 86-2
Test well Ch-Bf 146 was drilled to 1,650 ft below land surface to explore and evaluate the Patapsco Formation aquifers deeper than 1,000 ft in the Waldorf/La Plata area of Charles County, Maryland. The test hole penetrated two major aquifer systems above a depth of 1,000 ft and another major...
Rock riprap design for protection of stream channels near highway structures; Volume 1, Hydraulic characteristics of open channels
J. C. Blodgett
1986, Water-Resources Investigations Report 86-4127
Volume I discusses the hydraulic and channel properties of streams, based on data from several hundred sites. Streamflow and geomorphic data have been collected and developed to indicate the range in hydraulic factors typical of open channels , to assist design, maintenance, and construction engineers in preparing rock riprap bank...
Ground-water levels in Alaska, water year 1983
J.O. Brunett
1986, Open-File Report 86-56
Groundwater level data in Alaska are summarized for the 1983 water year for observation wells at which levels are either recorded continuously or measured intermittently. For wells at which water levels are measured semi-annually, 10-year summaries are presented. Water levels for 153 observation wells are shown on graphs and locations...
