Fluvial-sediment discharge to the oceans from the conterminous United States
Westley Farnsworth Curtis, James J. Culbertson, Edith B. Chase
1973, Circular 670
This report is a contribution to the UNESCO-sponsored project of the International Hydrological Decade called the World Water Balance. Annual fluvial-sediment discharge from the conterminous United States averages 491,449,600 short tons, of which 14,204,000 is discharged to the Atlantic Ocean, 378,179,000 to the Gulf of Mexico, and 99,066,600 to the...
Occurrence and distribution of selected metals in streams near Huntsville, Alabama
E. R. German, Alfred L. Knight
1973, Circular 679
Arsenic, cadmium, chromium, cobalt, lead, mercury, and zinc are widely distributed around Huntsville, Ala. However, concentrations of these metals in streamflow in the vicinity of the Huntsville municipal water intake during June, August, and September 1971 did not exceed the limits recommended for a public drinking water supply. The occurrence...
Electric-analog simulation network of unconsolidated aquifers in the upper Wabash River basin, Indiana
James E. Heisel
1973, Water-Resources Investigations Report 73-29
The ground-water budget of the unconsolidated deposits in the upper Wabash River basin was modeled. An electrical-simulation network was used to determine an integrated storage coefficient of 0.003 for the basin. Two practical problems were investigated: a municipal pumping problem and the change in flow regime due to the addition...
Hydrology of the dunes area north of Coos Bay, Oregon
J. H. Robison
1973, Open-File Report 73-241
Hydrology of a 20-square-mile area of dunes along the central Oregon coast was studied. The area is underlain by 80 to 150 feet of Quaternary dune and marine sand which overlies Tertiary marine clay and shale. Ground water for industrial and municipal use is being withdrawn at a rate of...
Bottom features and processes related to drifting ice on the Arctic shelf, Alaska
Erk Reimnitz, Peter W. Barnes, Tau Rho Alpha
1973, Miscellaneous Field Studies Map 532
Early investigations of artic shelf regions led to the hypothesis that certain micro-relief forms are related to the action of grounded ice (for example, Rex, 1955). Since the introduction of side-scan sonar as a tool for ocean-floor surveys, a number of workers have described the occurrence of linear bottom features...
