Chemical properties of ground water and their corrosion and encrustation effects on wells
Ivan Barnes, Frank Eldridge Clarke
1969, Professional Paper 498-D
Well waters in Egypt, Nigeria, and West Pakistan were studied for their chemical properties and corrosive or encrusting behavior. From the chemical composition of the waters, reaction states with reference to equilibrium were tested for 29 possible coexisting oxides, carbonates, sulfides, and elements. Of the 29 solids considered, only calcite,...

George Plafker, Reuben Kachadoorian, Edwin B. Eckel, Lawrence R. Mayo
1969, Professional Paper 542-G
The 1964 earthquake caused wide-spread damage to inhabited places throughout more than 60,000 square miles of south-central Alaska. This report describes damage to all communities in the area except Anchorage, Whittier, Homer, Valdez, Seward, the communities of the Kodiak group of islands, and communities in the Copper River Basin; these...
Erosion and deposition on a beach raised by the 1964 earthquake Montague Island, Alaska
M. J. Kirkby, Anne V. Kirkby
1969, Professional Paper 543-H
During the 1964 Alaska earthquake, tectonic deformation uplifted the southern end of Montague Island as much as 33 feet or more. The uplifted shoreline is rapidly being modified by subaerial and marine processes. The new raised beach is formed in bedrock, sand, gravel, and deltaic bay-head deposits, and the effect...

Edward F. McCarren, Walter B. Keighton
1969, Water Supply Paper 1879-H
The Lehigh River, 100 miles long, is the second largest tributary to the Delaware River. It drains 1,364 square miles in four physiographic provinces. The Lehigh River basin includes mountainous and forested areas, broad agricultural valleys and areas of urban and industrial development. In the headwaters the water is of...
Tectonics of the March 27, 1964, Alaska earthquake
George Plafker
1969, Professional Paper 543-I
The March 27, 1964, earthquake was accomp anied by crustal deformation-including warping, horizontal distortion, and faulting-over probably more than 110,000 square miles of land and sea bottom in south-central Alaska. Regional uplift and subsidence occurred mainly in two nearly parallel elongate zones, together about 600 miles long and as much...
A ground-water reconnaissance of the Republic of Ghana, with a description of geohydrologic provinces
H.E. Gill
1969, Water Supply Paper 1757-K
This report gives a general summary of the availability and use of ground water and describes the occurrence of ground water in five major geohydrologic provinces lying in the eight administrative regions of Ghana.

Water resources of the Salmon Falls Creek basin, Idaho-Nevada
E. G. Crosthwaite
1969, Water Supply Paper 1879-D
The northern part of the Salmon Falls Creek basin, referred to as the Salmon Falls tract, contains a large acreage of good agricultural land, but the surface-water supply is inadequate to develop the area fully. Attempts to develop ground water for irrigation have been successful only locally. Specific capacities of...
Evaluation and control of corrosion and encrustation in tube wells of the Indus Plains, West Pakistan
Frank Eldridge Clarke, Ivan Barnes
1969, Water Supply Paper 1608-L
Seepage from rivers and irrigation canals has contributed to waterlogging and soil salinization problems in much of the Indus Plains of West Pakistan. These problems are being overcome in part by tube-well dewatering and deep leaching of salinized soils. The ground waters described here are anaerobic and some are supersaturated...
Perspective center determination
J.D. McLaurin
1969, Open-File Report 70-209
This program determines coordinates of the perspective center of a stereoplotter projector by bringing two bundles of rays into a best fit coincidence in a space-resection solution. One of the bundles of rays is defined by the perspective center and the grid intersections on a grid plate. The other bundle...
Scientific or rule-of-thumb techniques of ground-water management--Which will prevail?
Charles Lee McGuinness
1969, Circular 608
Emphasis in ground-water development, once directed largely to quantitatively minor (but sociologically vital) service of human and stock needs, is shifting: aquifers are treated as possible regulating reservoirs managed conjunctively with surface water. Too, emphasis on reducing stream pollution is stimulating interest in aquifers as possible waste-storage media. Such management...

Atlantic continental shelf and slope of the United States - Color of marine sediments
D.J. Stanley
1969, Professional Paper 529-D
A systematic examination of the regional color distribution of the upper sediment layer on the Atlantic continental margin between Nova Scotia and southern Florida reveals that brown, dark green, and yellow predominate on the shelf north of Cape Hatteras, whereas olive, gray, and yellow predominate to the south. Color is...
Geohydrology and water utilization in the Willcox Basin, Graham and Cochise Counties, Arizona

The Willcox basin is an area of interior drainage in the northern part of Sulphur Springs Valley, Cochise and Graham Counties, Ariz. The basin comprises about 1,500 square miles, of which the valley floor occupies about 950 square miles. The basin probably formed during middle and late Tertiary time, when...

1969, Open-File Report 69-9
An aeromagnetic map covering 480 square miles was compiled for the Nixon Fork district, which is located approximately 35 miles northeast of McGrath, Alaska. The survey was flown in search of concealed intrusive rocks which may have produced contact metamorphic deposits in limestone similar to the known lode deposits which...

Stage-discharge characteristics of a Weir in a sand-channel stream
Don D. Gonzalez, C.H. Scott, James K. Culbertson
1969, Water Supply Paper 1898-A
A unique relation between water-surface elevation and water discharge usually does not exist for sand-channel streams. The relation is affected by changes in bed roughness and changes in bed elevation because of scour and fill. An artificial control on a sand-channel stream must control both the resistance to flow and...

1969, Initial reports of the Deep Sea Drilling Project (1) 403-410
The most dramatic variations in pore water composition occurred in Holes 2 and 3 in the Gulf of Mexico. Both holes showed a strong increase in salinity with depth, evidently owing to diffusion from underlying salt bodies. However, on Challenger Knoll (Hole 2) a sharp drop in salinity was observed...
