The environment of South Florida; a summary report
B. F. McPherson, G.Y. Hendrix, Howard Klein, H.M. Tyus
1976, Professional Paper 1011
Man has altered the original south Florida ecosystem to a new three-part ecosystem which incorporates an agricultural component, an urban component, and a component of the original ecosystem that is largely unchanged but still has been affected by man. These components are interrelated through the flow of energy and material....
Regional appraisal of the Wilcox Group in Texas for subsurface storage of fluid wastes: Part 1: Geology
Paul Hastings Jones, P. R. Stevens, J. B. Wasselman, R. H. Wallace Jr.
1976, Open-File Report 76-394
Sandy beds of the Wilcox Group in Texas are underlain and overlain by clays of the Midway and Claiborne Groups. The Wilcox is divided by a persistent shale wedge. Contrasting delta systems described as high-constructive and high-destructive exist in the divisions. Merged high constructive deltas characterize the lower, while the...
Summary appraisals of the nation's ground-water resources – Great Basin region
Thomas E. Eakin, Don Price, J. R. Harrill
1976, Professional Paper 813-G
Ground-water withdrawals by wells in the Great Basin Region were about 1.1 million acre-feet (1,360 cubic hectometres) in 1970. Most of these withdrawals were from 87 of the 234 hydrographic areas in the region. Withdrawals ranged from about 1,000 acre-feet (1.2 cubic hectometres) to more than 100,000 acre-feet (123 cubic...
Summary appraisals of the nation's ground-water resources – California region
H. E. Thomas, D. A. Phoenix
1976, Professional Paper 813-E
Most people in the California Region live in a semiarid or arid climate, with precipitation less than the potential evapotranspiration- environments of perennial water deficiency. The deficiency becomes most onerous during the characteristically rainless summers and during recurrent droughts that may continue for 10--20 years. However, water from winter rain...
Boundaries of the United States and the several States
F. K. Van Zandt
1976, Professional Paper 909

This U.S. Geological Survey activities report includes a summary of recent (1976 fiscal year) scientific and economic results accompanied by a list of geologic and hydrologic investigations in progress and a report on the status of topographic mapping. The summary of results includes: (1) Mineral resources, Water resources, (2) Engineering...
Summary appraisals of the nation's ground-water resources–Texas-Gulf region
E. T. Baker Jr., J. R. Wall
1976, Professional Paper 813-F
Ground water in the Texas-Gulf Region is a large and important resource that can provide a more significant percentage of the total water supply of the region. Total water requirements within the region are projected to rise sharply from 14 million acre-feet (17 cubic kilometres) in 1970 to nearly 26...
Summary appraisals of the nation's ground-water resources – Arkansas-White-Red region
M. S. Bedinger, R. T. Sniegocki
1976, Professional Paper 813-H
The Arkansas-White-Red Region, an area of265,000 square miles (6.86x1011 square metres), is characterized by diversity in geography, climate, and geology and, in turn, by diversity in water resources and water problems. The western semiarid part of the region is water deficient, that is, potential evapotranspiration exceeds precipitation. The eastern, humid part...
