Geohydrologic aspects for siting and design of low-level radioactive-waste disposal
M. S. Bedinger
1989, Circular 1034
The objective for siting and design of low-level radioactive-waste repository sites is to isolate the waste from the biosphere until the waste no longer poses an unacceptable hazard as a result of radioactive decay. Low-level radioactive waste commonly is isolated at shallow depths with various engineered features to stabilize the...
Measurement of time of travel in streams by dye tracing
F. A. Kilpatrick, James F. Wilson
1989, Techniques of Water-Resources Investigations 03-A9
The use of fluorescent dyes and tracing techniques provides a means for measuring the time-of-travel and dispersion characteristics of steady and gradually varied flow in streams. Measurements of the dispersion and concentration of dyes give insight into the behavior of soluble contaminants that may be introduced into a stream. This manual describes methods of measuring time...
The United States Geological Survey: 1879-1989
Mary C. Rabbitt
1989, Circular 1050
The United States Geological Survey was established on March 3, 1879, just a few hours before the mandatory close of the final session of the 45th Congress, when President Rutherford B. Hayes signed the bill appropriating money for sundry civil expenses of the Federal Government for the fiscal year beginning...
Isotopic evidence for evolution of sub-continental mantle during Red Sea rifting
John S. Pallister, Ernst Hegner
1989, Open-File Report 89-335
Tertiary igneous rocks from near Al Lith, Saudi Arabia are alkaline to subalkaline and bimodal in composition, and document early and late rift volcanism (≥30 Ma to ~20 Ma, 11 Ma and 3 Ma) in the central part of the Red Sea rift. Isotopic and trace-element data from twenty-five samples...
The U.S. Geological Survey Federal-State Cooperative Water- Resources Program: Fiscal Year 1988
Bruce K. Gilbert, William B. Mann IV
1989, Open-File Report 89-389
The Federal-State Cooperative Program is a partnership between the U.S. Geological Survey and State and local agencies. It provides a balanced approach to the study and resolution of water-related problems and to acquiring hydrologic data. The principal program objectives are to: (1) collect, on a systematic basis, data needed for...
IRIS/USGS plans for upgrading the Global Seismograph Network
Jon Peterson, Charles R. Hutt
1989, Open-File Report 89-471
This report has been prepared to provide information to organizations that may be asked to participate in a program to upgrade the global seismographic network. In most cases, the organizations that will be offered new instrumentation by the U.S. Geological Survey currently operate stations in the World-Wide Standardized Seismograph Network...
