Simulations of water-level drawdowns in proposed well-field areas, Dade County, Florida
Howard Klein
1976, Open-File Report 76-651
Electrical analog model simulations of hydraulic conditions in the Biscayne aquifer were made at proposed inland well-field sites in Dade County, Florida. Simulated drawdowns of water levels after 7 months of continuous pumping at 50, 100, and 150 million gallons per day were obtained at each site. Simultaneous pumping of...
Geologic data from test drilling in Palm Beach County, Florida since 1970
James J. Schneider
1976, Open-File Report 76-713
Test hole data, in Palm Beach County, Florida, include lithologic logs from 66 test wells and geophysical logs from 54 test wells. The purpose of the study is to provide the geohydrologic information needed for water management and land use decisions, with emphasis on the urbanized eastern part of the...
Nitrogen and phosphorus uptake in the Everglades Conservation Areas, Florida, with special reference to the effects of backpumping runoff
Benjamin F. McPherson, Bradley G. Waller, H. C. Mattraw
1976, Water-Resources Investigations Report 76-29
In much of the water pumped into the northern Everglades, Florida, concentrations of inorganic nitrogen and phosphorus are relatively high. These nutrients are transported in the canals or into the peripheral marshes. Concentrations decrease sharply within 330 feet or less of the canals, whereas specific conductance remains essentially unchanged within...
Analog-model simulations for secondary canal controls and forward pumping water-management schemes in southeast Florida
E. H. Cordes, Richard Alfred Gardner
1976, Water-Resources Investigations Report 76-93
The analog model of the Biscayne aquifer of southeast Florida was used to approximate the effects of two proposed water-management schemes. One involved adding a secondary control structure in a major canal which is controlled near the coast. In the model the controls were operated in accordance with canal water...
Analysis of selected benthic communities in Florida Everglades with reference to their physical and chemical environment
Bradley G. Waller
1976, Water-Resources Investigations Report 76-28
Species diversity and numbers of benthic macroinvertebrates were determined at 12 sites, both canals and marshes, in the Everglades of south Florida. The values calculated are used to indicate long-term trends in water quality and variations between study areas.Species diversity at all sites was generally in a range indicative of...
Lakes of Oregon, Volume 4: Clackamas County
M.V. Shulters
1976, Report
An inventory of lakes and reservoirs of Oregon is essential for a complete evaluation of the total surface-water supply of the State and to provide a basis for answering questions about Oregon's lakes. Much of the information on lakes and reservoirs previously collected by Federal and State agencies has never...
Coral reef recovery in Florida and the Persian Gulf
Eugene A. Shinn
1976, Environmental Geology (1) 241-254
Long-term observations and study of coral reef destruction by hurricanes in the Florida Keys show, surprisingly, that although corals are devastated on a grand scale during storms, recovery is rapid. Recovery occurs because of the widespread scattering of live fragments, many of which become growth sites...
Steps to the moon
Water Resources Division, U.S. Geological Survey, Alvin E. Dale
1976, Report
On July 20, 1969, man walked on the surface of the Moon and began a new chapter of his studies that will eventually disclose the geologic nature of the Earth's nearest neighbor. Although he has finally reached the Moon and sampled its substance, much work and study remain before he...
National Cartographic Information Center (NCIC)
Water Resources Division, U.S. Geological Survey
1976, Report
The National Cartographic Information Center (NCIC), established by the U.S. Geological Survey, Department of the Interior, in July 1974, provides a national information service to make cartographic data of the United States more easily accessible to the public and to various Federal, State, and local agencies. At present, more than...
Access routes to the U.S. Geological Survey's EROS Data Center, Sioux Falls, South Dakota
Water Resources Division, U.S. Geological Survey
1976, Report
The EROS Data Center is a part of the Earth Resources Observation Systems (EROS) Program of the Department of the Interior, managed by the U.S. Geological Survey. It is the national center for the processing anddissemination of spacecraft and aircraft acquired photographic imagery and electronic data of the Earth's resources....
Computation of unsteady flows in rivers and estuaries by the method of characteristics
Chintu Lai, C. A. Onions
1976, Report
This report is a program documentation to the latest revision (1975) of the unsteady open-channel flow simulation model by the method of characteristics, Version 13 in the program series, which employs a multiple-reach scheme treating each subreach as a prismatic shape. A long waterway of variable cross section, properties and...
A reward band study of mallards to estimate band reporting rates
Charles J. Henny, K.P. Burnham
1976, Journal of Wildlife Management (40) 1-14
Reward bands ($10) were placed on 2,122 hatching-year mallards (Anas platyrhynchos), and an additional 11,490 received conventional bands (controls) to estimate band reporting rates. An analysis of band recoveries indicated that the reporting rate was dependent primarily upon three factors: (1) the distance banded birds were recovered from the banding...
