Estimation of background loadings and concentrations of phosphorus for lakes in the Puget Sound region, Washington
Robert J. Gilliom
1980, Open-File Report 80-328
For lakes in watersheds that include developed land, evaluation of eutrophication is facilitated by knowledge of changes in the lakes ' phosphorus concentration since development. A method is described for estimating background phosphorus concentration in lakes of the Puget Sound lowland, Washington. Using a mass-balance ' Vollenweider-type ' model, phosphorus...
U.S. Geological Survey role in earthquake prediction
David P. Hill
1980, Open-File Report 80-144
Work in the Seismology Branch on the problem of earthquake prediction is based primarily on the recording and analysis of seismic (elastic) waves in the Earth generated either by earthquakes themselves or by artificial sources such as quarry blasts or explosions detonated in drill holes. At the present time this...
The influences of land use and land cover on climate; an analysis of the Washington-Baltimore area that couples remote sensing with numerical simulation
R.W. Pease, C.B. Jenner, J.E. Lewis Jr.
1980, Professional Paper 1099-A
The Sun drives the atmospheric heat engine by warming the terrestrial surface which in turn warms the atmosphere above. Climate, therefore, is significantly controlled by complex interaction of energy flows near and at the terrestrial surface. When man alters this delicate energy balance by his use of the land, he...
Digital-model projection of saturated thickness and recoverable water in the Ogallala Aquifer, Texas County, Oklahoma
Robert B. Morton
1980, Open-File Report 79-565
A digital model was used to provide a quantitative description of the Ogallala aquifer in Texas County, Oklahoma, and to predict saturated thickness and water in storage from the aquifer at specified future times. The Ogallala aquifer, which consists of unconsolidated sand, gravel, and clay, is the principal source of...
Relationships between basic soils-engineering equations and basic ground-water flow equations
Donald G. Jorgensen
1980, Water Supply Paper 2064
The many varied though related terms developed by ground-water hydrologists and by soils engineers are useful to each discipline, but their differences in terminology hinder the use of related information in interdisciplinary studies. Equations for the Terzaghi theory of consolidation and equations for ground-water flow are identical under specific conditions....

Daniel C. Gillies, Wayne W. Lapham
1980, Open-File Report 80-1105
A revised dewatering plan for the construction of a nuclear power plant at the Northern Indiana Public Service Company 's (NIPSCO) Bailly Generating Station and evidence that suggests that a change in the characteristics of the confining unit 2 in and near Cowles Bog National Landmark may exist have resulted...
Computer-model analysis of the use of Delaware River water to supplement water from the Potomac-Raritan-Magothy aquifer system in southern New Jersey
Arlen W. Harbaugh, J. E. Luzier, Flavian Stellerine
1980, Water-Resources Investigations Report 80-31
A computer model of the Potomac-Raritan-Magothy aquifer system was used to simulate the effects of supplementing ground water with water from the Delaware River. Replacement of ground water pumpage with surface water in a 150-square-mile area near Camden, N.J., was simulated. Artificial recharge of surface water was also simulated in...
Field survey of intensity for the earthquake of July 27, 1980, Sharpsburg, Kentucky

The magnitude 5.2 (mb) northern Kentucky earthquake of July 27, 1980, at 18:52:21.8 UTC, located at 38.17N, 83.91W with a depth of 8 km (as determined by the National Earthquake Information Service), was particularly notable for the widespread damage it did, especially to older chimneys. Investigators from several different organizations...
Effects of urbanization on the water quality of lakes in Eagan, Minnesota
M. A. Ayers, G. A. Payne, Mark A. Have
1980, Water-Resources Investigations Report 80-71
Water-quality characteristics of 17 lakes and ponds in the city of Eagan were described from data collected from 1972 through 1978. The data showed that differences in water quality between lakes were related to differences in the percentage of urbanization. However, water-quality variations within each lake were affected more by...
