Summary appraisals of the nation's ground-water resources – Lower Colorado region
E. S. Davidson
1979, Professional Paper 813-R
This report summarizes ground-water availability in the lower Colorado region and discusses the potential for greater ground-water development and increased efficiency of water use. The climate in the most highly developed southwestern part of the region is warm and dry and that in the northeastern part is cool and moist to...
Summary appraisals of the nation's ground-water resources– South Atlantic-Gulf region
D.J. Cedarstrom, E. H. Boswell, G. R. Tarver
1979, Professional Paper 813-O
Precipitation in the 270,000-square-mile South Atlantic-Gulf Region ranges from 44 to 80 inches, and the average runoff is about 15 inches. The ground-water discharge that forms the base flow of streams is conservatively estimated to be about 78,000 million gallons per day the equivalent of about 6 inches of precipitation....

1979, Open-File Report 79-329
One-hundred-eight samples of bed material were collected from the Amazon River and its major tributaries between Belem, Brazil , and Iquitos, Peru. Samples were taken with a standard BM-54 sampler or with pipe dredges from May 18 to June 5, 1977. Most of the samples have median diameters in the...
