Can rain cause volcanic eruptions?
Larry G. Mastin
1993, Open-File Report 93-445
Volcanic eruptions are renowned for their violence and destructive power. This power comes ultimately from the heat and pressure of molten rock and its contained gases. Therefore we rarely consider the possibility that meteoric phenomena, like rainfall, could promote or inhibit their occurrence. Yet from time to time observers have...
Estimation of unit hydrographs for large floods at ungaged sites in Montana
S.R. Holnbeck, Charles Parrett
1993, Open-File Report 93-168
Methods were developed for estimating unit hydro- graphs at ungaged sites in Montana using either the Clark or dimensionless unit-hydrograph method. Flood hydrograph data for 26 U.S. Geological Survey streamflow-gaging stations and rainfall data were used together with a rainfall-runoff simulation model (HEC-1) to derive unit hydrographs and important unit-hydrograph...
Water-resources investigations in Wisconsin, 1993
D. E. Maertz
1993, Open-File Report 93-129
PROBLEM: Surface-water information is needed for surveillance, planning, design, hazard warning, operation, and management in water-related fields such as water supply, hydroelectric power, flood control, irrigation, bridge and culvert design, wildlife management, pollution abatement, flood-plain management, and water-resources development. An appropriate data base is necessary to provide this information. OBJECTIVE: The...
U.S. Geological Survey; North Carolina's water resources; a partnership with State, Federal and local agencies
M. D. Winner Jr.
1993, Open-File Report 93-113
For more than 80 years, the Federal-State Cooperative Program in North Carolina has been an effective partnership that provides timely water information for all levels of government. The cooperative program has raised awareness of State and local water problems and issues and has enhanced transfer and exchange of scientific information....
Report of the U.S. Geological Survey's evaluation program for standard reference samples distributed in April 1993; T-123 (trace constituents), T-125 (trace constituents), M-126 (major constituents, N-38 (nutrients), N-39 (nutrients), P-20 (low ionic strength, and Hg-16 (mercury)
H.K. Long, J.W. Farrar
1993, Open-File Report 93-436
This report presents the results of the U.S. Geological Survey's analytical evaluation program for seven standard reference samples--T-123 (trace constituents), T-125 (trace constituents), M-126 (major constituents), N-38 (nutrients), N-39 (Nutrients), P-20 (precipitation-low ionic strength), and Hg-16 (mercury)--that were distributed in April 1993 to 175 laboratories registered in the U.S. Geological...
Ground-water data for Michigan 1990
G.C. Huffman, C.R. Whited
1993, Open-File Report 92-114
Water levels, locations, depths, and aquifers tapped are given for 107 observation wells. Tabulated data include a listing of ground-water reports in Michigan, extremes of water levels for calendar year 1990 and for the period of record, pumpage of most major ground-water users in the State, and a map showing...
