Geohydrology of the northern Louisiana salt-dome basin pertinent to the storage of radioactive wastes; a progress report
R. L. Hosman
1978, Water-Resources Investigations Report 78-104
Salt domes in northern Louisiana are being considered as possible storage sites for nuclear wastes. The domes are in an area that received regional sedimentation through early Tertiary (Eocene) time with lesser amounts of Quaternary deposits. The Cretaceous-Tertiary accumulation is a few thousand feet thick; the major sands are regional...
Potential potable-water supplies in Redwood National Park, California
J. P. Akers
1978, Open-File Report 78-970
An evaluation was made of the potential for potable-water supplies at 13 sites in or near Redwood National Park, Calif. The National Park Service is planning for the development of visitor facilities at these sites. At some sites, the report recommends using surface-water diversions. At other sites, locations are given...

Maps showing ground-water conditions in the Willcox area, Cochise and Graham Counties, Arizona - 1975
Larry J. Mann, Natalie D. White, R. P. Wilson
1978, Water-Resources Investigations Report 78-60
The Willcox area includes about 1,500 square miles in southeastern Arizona. The main use of ground water is for irrigation. For 1954-75, the estimated ground-water pumpage exceeded 100,000 acre-feet per year, and for 1967-75, ground-water pumpage averaged about 300,000 acre-feet per year. Ground-water withdrawals have resulted in general water-level declines...
Hydrological applications of Landsat imagery used in the study of the 1973 Indus River flood, Pakistan
Morris Deutsch, F.H. Ruggles Jr.
1978, Journal of the American Water Resources Association (14) 261-274
During August and September 1973, the Indus River Valley of Pakistan experienced one of the largest floods on record, resulting in damages to homes, businesses, public works, and crops amounting to millions of rupees. Tremendous areas of lowlands were inundated along the Indus River and major tributaries. Landsat data made...
Flood damage assessment using computer-assisted analysis of color infrared photography
William H. Anderson
1978, Journal of Soil and Water Conservation (33) 283-286
Use of digitized aerial photographs for flood damage assessment in agriculture is new and largely untested. However, under flooding circumstances similar to the 1975 Red River Valley flood, computer-assisted techniques can be extremely useful, especially if detailed crop damage estimates are needed within a relatively short period of time.Airphoto interpretation...

Simulation model of Cryptomonas ovata population dynamics in southern Kootenay Lake, British Columbia
James E. Cloern
1978, Ecological Modelling (4)-133
A one-dimensional transient model is developed to simulate observed population dynamics of a small flagellate (Cryptomonas ovata) in southern Kootenay Lake, B.C., during a 1-year period (1 June 1974-31 May 1975). The model considers advective displacement of C. ovata as water flows from its southern entrance into the lake and moves northward...

Oxygen isotope composition of subglacially precipitated calcite: Possible paleoclimatic implications
B.B. Hanshaw, B. Hallet
1978, Science (200) 1267-1270
Isotopic analyses of subglacially precipitated calcite from near a modern temperate glacier show that the δ18O (= 18O/ 16O relative to standard mean ocean water) of the calcite records the δ18O of the ice from that glacier. It may therefore be possible to determine the δ18O of Pleistocene ice sheets on the...
