Municipal ground-water development and withdrawals in the central Lower Peninsula of Michigan, 1870-1987
M.A. Baltusis, M.F. Quigley, Richard J. Mandle
1992, Open-File Report 91-215
Municipal water-supply systems in the central Lower Peninsula of Michigan were categorized into four regions on the basis of source of water for 1987. These categories included water systems that obtained water from aquifers in glacial drift, bedrock, or both, as well as those that obtained water from surface-water sources....
A computer program (MODFLOWP) for estimating parameters of a transient, three-dimensional ground-water flow model using nonlinear regression
Mary Catherine Hill
1992, Open-File Report 91-484
This report documents a new version of the U.S. Geological Survey modular, three-dimensional, finite-difference, ground-water flow model (MODFLOW) which, with the new Parameter-Estimation Package that also is documented in this report, can be used to estimate parameters by nonlinear regression. The new version of MODFLOW is called MODFLOWP (pronounced MOD-FLOW*P),...
Water-resources activities of the U.S. Geological Survey in Kansas; fiscal years 1989,1990, and 1991
1992, Open-File Report 92-90
The principal mission of the U. S. Geological Survey, Water Resources Division, in Kansas is to investigate the occurrence, quantity, quality, distribution, and movement of surface and ground water throughout the State. Primary activities include the systematic collection, analysis, and interpretation of hydrologic data, evaluation of water demands, and water-resources...
Water-resources activities of the U.S. Geological Survey in Illinois, 1991
G. O. Balding (compiler)
1992, Open-File Report 92-452
This report gives an overview of U.S. Geological Survey, Illinois District, Water Resources Division activities related to the water resources of the State of Illinois. The report includes sections describing District organization, programs, water conditions, data collection activities, and project summaries. Also included is a complete listing of District and...
Water-resources activities of the U.S. Geological Survey in Illinois, 1990
G. O. Balding (compiler)
1992, Open-File Report 92-451
This report gives an overview of U.S. Geological Survey, Illinois District, Water Resources Division activities related to the water resources of the State of Illinois. The report includes sections describing District organization, programs, water conditions, data collection activities, and project summaries. Also included is a complete listing of District and...
Hydrologic data for the Big Spring basin, Clayton County, Iowa, water year 1990
Stephen J. Kalkhoff, R.L. Kuzniar, D. Kolpin, C.A. Harvey
1992, Open-File Report 92-67
Hydrologic data were collected in the Big Spring basin located in Clayton County, Iowa, during the 1990 water year. The data were collected by the U.S. Geological Survey in cooperation with the Iowa Department of Natural Resources, Geological Survey Bureau, to provide information on variation and movement of agricultural chemicals...
A method of estimating the amount of in-situ gas hydrates in deep marine sediments
Myung W. Lee, D. R. Hutchinson, William P. Dillon, J. J. Miller, Warren F. Agena, B.A. Swift
1992, Open-File Report 92-276
The bulk volume of gas hydrate in marine sediment can be estimated by measuring interval velocities and amplitude blanking of hydrated zones from true-amplitude processed multichannel seismic reflection data. In general, neither velocity nor amplitude information is adequate to independently estimate hydrate concentration. We propose a method that uses amplitude...
Micrometeorological measurements at Ash Meadows and Corn Creek Springs, Nye and Clark counties, Nevada, 1986-87
M. J. Johnson, Alex Pupacko
1992, Open-File Report 92-650
Micrometeorological data were collected at Ash Meadows and Corn Creek Springs, Nye and Clark Counties, Nevada, from October 1, 1986 through September 30, 1987. The data include accumulated measurements recorded hourly or every 30 minutes, at each site, for the following climatic variables: air temperature, wind speed, relative humidity, precipitation,...
