Harold E. McGovern, L. J. Combs
1981, Open-File Report 81-348
Activities of the U.S. Geological Survey in Kansas include the systematic collection and analysis of data to describe the framework of hydrologic systems, assess the water resources, define existing or potential problems in the quantity or quality of water, and provide information for optimum development and management of resources. Streamflow...
Water-resources investigations of the U.S. Geological Survey in Colorado: fiscal year 1981
W.E. Price
1981, Open-File Report 81-150
The report provides an overview of water-resources data collection and hydrologic investigations in Colorado from October 1, 1980, to September 30, 1981. Most of the work is carried out in cooperation with 51 Federal, State, and local agencies. Data are being collected at 503 surface-water gaging stations, 161 surface-water quality...
Use of flow-duration curves to evaluate effects of urbanization on streamflow patterns on Long Island, New York
Keith R. Prince
1981, Water-Resources Investigations Report 80-114
Streamflow patterns on Long Island, N.Y., have been changing over the last three decades in response to eastward population growth and urbanization. Flow-duration curves for nine streams in Nassau and Suffolk Counties indicate that, during this time, streams in urbanized areas have had increased peak flows and decreased base flows,...

1981, Open-File Report 81-1003
During fiscal year 1981 there were 20 water-resources investigations in progress by the Arkansas District of the U. S. Geological Survey 's Water Resources Division. Investigations that mainly involved data collection included surface-water gaging, water-level measuring, water-quality sampling, sediment sampling, and water-use inventorying. Interpretive studies included three that were principally...
Leachability of uranium and other elements from freshly erupted volcanic ash
David B. Smith, Robert A. Zielinski, William I. Rose Jr.
1981, Open-File Report 81-118
A study of leaching of freshly erupted basaltic and dacitic air-fall ash and bomb fragment samples, unaffected by rain, shows that glass dissolution is the dominant orocess by which uranium is initially mobilized from air-fall volcanic ash. Si, Li, and V are also Preferentially mobilized by glass dissolution. Gaseous transfer...
