Uranium values from ion-filter water sampling compared with values from bulk-water sampling
Robert Allen Cadigan, J. Karen Felmlee
1978, Open-File Report 78-472
Analytical values of uranium from well water sampled by means of ion-filters were compared with analytical values of the same water sampled by the standard bulk (1-liter) water-sampling technique (Brown, Skougstad and Fishman, 1970). A fluorometric extraction method of analysis was used on both sets of samples. Duplicate samples from...
The case of the shrinking channels; the North Platte and Platte rivers in Nebraska
Garnett P. Williams
1978, Circular 781
Since the latter part of the 19th century, channels of North Platte and Platte Rivers in western and central Nebraska have changed considerably. In the 365-km reach from Minatare to Overton, the channel by 2969 ws only about 0.1-0.2 as wide in 1865. The 1969 channel for this reach was...
Program for evaluating stream quality in North Carolina
Hugh B. Wilder, Clyde E. Simmons
1978, Circular 764
The design and objectives of the program for evaluating stream quality in North Carolina are described. Using water-quality and streamflow data collected since the 1940's, a study is underway to define certain variations in water quality, to quantify the effects of man 's activities on water quality, and to determine...
A theoretical basis for exploration for native copper in northern Wisconsin
Walter S. White
1978, Circular 769
Exploration for native copper in the Keweenawan lavas of northern Wisconsin has been concentrated in areas of relatively shallow overburden that have sparse to numerous outcrops. Lack of success of this exploration suggests that if large deposits, comparable to those of northern Michigan, are present, they are more likely to...
Water-quality indices for specific water uses
J.D. Stoner
1978, Circular 770
Water-quality indices were developed to assess waters for two specific uses--public water supply and irrigation. The assessment for a spcific water use is based on the availability f (of (1) a set of limits for each water quality property selected, (2) a rationale for selection, and (3) information that permits...

The papers were presented by members of the U.S. Geological Survey at the International Seminar on Organization and Operation of Hydrologic Services, Ottawa, Canada, July 15-16, 1976, sponsored by the...
A guide to obtaining information from the USGS 1978
Paul F. Clarke (compiler), Helen E. Hodgson, Gary W. North
1978, Circular 777
For almost 100 years, the USGS (U.S. Geological Survey) has served Federal, State, and local governments and the public by collecting, analyzing, and publishing detailed information about the Nation 's mineral, land, and water resources. This information is released in a variety of map, book, and other formats and is...
Reconnaissance investigation of high-calcium marble in the Beaver Creek area, St. Lawrence County, New York
C. Ervin Brown
1978, Circular 774
Three belts of marble of the Grenville Series were mapped in the Beaver Creek drainage basin, St. Lawrence County, N.Y. One of these, on the west side of Beaver Creek, consists of coarsely crystalline pure calcitic marble that occurs in a zone at least 10 by 0.8 km in extent....

Stratigraphic test well, Nantucket Island, Massachusetts
David W. Folger, J.C. Hathaway, R. A. Christopher, P. C. Valentine, C. W. Poag
1978, Circular 773
The U.S. Geological Survey, in cooperation with the Massachusetts Water Resources Commission and the Nantucket Conservation Foundation, continuously cored 514 m of sediment and volcanic rock in a stratigraphic and water-quality test near the geographic center of Nantucket Island. Stratified sediments were divided texturally into three zones: the upper zone...
The United States Geological Survey in Alaska: Accomplishments during 1977
Kathleen M. Johnson, editor(s)
1978, Circular 772-B
United States Geological Survey projects in Alaska study a wide range of topics of economic and scientific interest. Work done in 1977 includes contributions to economic geology, regional geology, stratigraphy, engineering geology, hydrology, and marine geology. Many maps and reports covering various aspects of the geology and mineral and water...

Computer model of two-dimensional solute transport and dispersion in ground water
Leonard F. Konikow, J.D. Bredehoeft
1978, Techniques of Water-Resources Investigations 07-C2
This report presents a model that simulates solute transport in flowing ground water. The model is both general and flexible in that it can be applied to a wide range of problem types. It is applicable to one- or two-dimensional problems involving steady-state or transient flow. The model computes changes...
Rock pushing and sampling under rocks on Mars
H. J. Moore, S. Liebes Jr., D.S. Crouch, L.V. Clark
1978, Professional Paper 1081
Viking Lander 2 acquired samples on Mars from beneath two rocks, where living organisms and organic molecules would be protected from ultraviolet radiation. Selection of rocks to be moved was based on scientific and engineering considerations, including rock size, rock shape, burial depth, and location in a sample field. Rock...

1978, Professional Paper 1068
Sites with drainage areas ranging from 88 to 12,200 sq km were monitored on five streams in northern Alaska during the breakup in 1976 to determine (1) the effects of frozen bed and bank material on channel behavior, and (2) the importance of the annual breakup flood in forming the...
Erosion and sediment yields in the Transverse Ranges, Southern California
Kevin M. Scott, Rhea P. Williams
1978, Professional Paper 1030
Major-storm and long-term erosion rates in mountain watersheds of the western Transverse Ranges of Ventura County, Calif., are estimated to range from low values that would not require the construction of catchments or channel-stabilization structures to values as high as those recorded anywhere for comparable bedrock erodibilities. A major reason...
Field determination of vertical permeability to air in the unsaturated zone
Edwin P. Weeks
1978, Professional Paper 1051
The vertical permeability to air of layered materials in the unsaturated zone may be determined from air pressure data obtained at depth during a period when air pressure is changing at land surface. Such data may be obtained by monitoring barometric pressure with a microbarograph or surveying altimeter and simultaneously...
Hydraulic geometry of river cross sections; theory of minimum variance
Garnett P. Williams
1978, Professional Paper 1029
This study deals with the rates at which mean velocity, mean depth, and water-surface width increase with water discharge at a cross section on an alluvial stream. Such relations often follow power laws, the exponents in which are called hydraulic exponents. The Langbein (1964) minimum-variance theory is examined in regard...
