Physical and chemical properties of the Potomac River and environs, August 1978
Richard E. Smith, Raynol E. Herndon
1980, Open-File Report 80-746
Basic data on the physical and chemical properties measured over the period 21 August through 31 August 1978 on the tidally influenced Potomac River and estuary are presented herein. Forty-two vertical profiles, and approximately 170 surface observations were made of the distributions of salinity, temperature, light transmission, chlorophyll-a fluorescence, dissolved...
Water-resources data collected in the Devils Hole area, Nye County, Nevada, 1977-1978
R.L. Carson
1980, Open-File Report 80-772
This report presents water data collected at Devils Hole and vicinity for July 1977 through June 1978 to observe the effects of irrigation pumping on the pool level in Devils Hole. The pool contains the endangered species of pupfish, Cyprinodon diabolis. The report presents data on fluctuations in water level...
Results and evaluation of a pilot primary monitoring network, San Francisco Bay, California, 1978
W.L. Bradford, R.T. Iwatsubo
1980, Water-Resources Investigations Report 80-73
A primary monitoring network of 12 stations, with measurements at 1-meter depth intervals every 2 weeks during periods of high inflow from the Sacramento-San Joaquin River delta, and every 4-6 weeks during seasonal low delta inflows, appears adequate to observe major changes in ambient water quality in San Francisco Bay....
Seismicity map of the State of New Jersey
C. W. Stover, L.M. Barnhard, B.G. Reagor, S. T. Algermissen
1980, Miscellaneous Field Studies Map 1260
This map is one of a series of seismicity maps produced by the U.S. Geological Survey that show earthquake data of individual states or groups of states at the scale of 1:1,000,000. This map shows only those earthquakes with epicenters located within the boundaries of New Jersey, even though earthquakes...
Preliminary data describing the distribution of fluoride and silica in the water in the Ogallala aquifer on the High Plains of Texas
R.L. Bassett, S.G. Perkins, R. K. Waddell
1980, Open-File Report 80-349
The Ogallala aquifer of Texas historically has been known for elevated fluoride concentration, with many areas in excess of 4 milligrams per liter. In addition, on a regional scale, silica concentrations are also somewhat elevated, with concentrations averaging in the 40 to 50 milligrams per liter range. This aquifer provides...
Extension of transient-flow model of the Sacramento River at Sacramento, California
Richard N. Oltmann
1980, Water-Resources Investigations Report 80-30
The multiple-reach method-of-characteristics flow-simulaltion model that was successfully applied in 1976 to a 10.8-mile tide-affected reach of the Sacramento River, in California, from Sacramento to Freeport has been extended 10.5 miles farther downstream of Hood. The model reach was extended to improve the quality of the model 's output during...
Water quality in Rhode River at Smithsonian Institution Pier near Annapolis, Maryland, January 1976 through December 1978
Robert L. Cory, P.V. Dresler
1980, Water-Resources Investigations Report 79-109
Water temperature, salinity, turbidity, dissolved oxygen, pH, and water level data were continuously monitored and recorded from the Smithsonian Institution pier near Annapolis, Md., from January 1976 through December 1978. Daily maximum and minimum values are tabulated and summarized, and monthly averages and extremes are presented. Water temperature ranged from...
Water resources data for Massachusetts and Rhode Island, water year 1979
Water Resources Division, U.S. Geological Survey
1980, Water Data Report MA-RI-79-1
Water-resources data for the 1979 water year for Massachusetts and Rhode Island consist of records of stage, discharge, and water quality of streams; contents of lakes and reservoirs; and ground-water levels. This report contains discharge records for 102 gaging stations, month end contents for 30 lakes and reservoirs, water quality...
Thermal modeling of flow in the San Diego Aqueduct, California, and its relation to evaporation
Harvey E. Jobson
1980, Professional Paper 1122
The thermal balance of the 26-kilometer long concrete-lined San Diego Aqueduct, a canal in southern California, was studied to determine the coefficients in a Dalton type evaporation formula. Meteorologic and hydraulic variables, as well as water temperature, were monitored continuously for a 1-year period. A thermal model was calibrated by...
Flood magnitude and frequency of small streams in Indiana: Preliminary estimating equations
Robert L. Gold
1980, Open-File Report 80-759
This interim report presents preliminary estimating equations developed for the ongoing study, "Flood Frequency of Small Streams in Indiana." The equations were developed by the multiple-regression technique from data collected at 57 crest-stage-gage and 15 rainfall-runoff sites in the study and from 133 streamflow stations in Indiana and 11 in...
1979 annual index of current earthquake literature
M.L. Gunn, B.S. Hayashida, William Hung Kan Lee
1980, Open-File Report 80-238
In the past several years, earthquake research has been greatly accelerated in China, Japan, USSR and the United States. Presently, about 3,000 earthquake-related publications (including meeting abstracts) are produced yearly. In order to keep up with this current literature, a computer-based bibliographic system was implemented as part of a research...
