The Sea Data 651-4 data logger
David S. Hosom, Bradford Butman
1981, Open-File Report 81-111
This paper describes a digital data logger used as the primary controller and data collection device for the U.S. Geological Survey Sediment Monitoring Tripod Program. The tripods are deployed at sea in water depths up to 100 m for periods of 3 to 6 months. The system measures bottom current...
Clay mineralogy of Devonian shales in the Appalachian Basin
John W. Hosterman, Sallie I. Whitlow
1981, Open-File Report 81-585
A study of the clay mineralogy of the Devonian black shales of the Appalachian basin was undertaken to help predict areas for potential gas resources. More than 2,100 samples from 84 drill holes representing 11 shale units were analyzed for clay mineralogy or whole—rock mineralogy or both. Approximately 1,300 samples...
An assessment of streamflow, water quality, and the effects of constructing an impoundment on Bridge Creek at Augusta, Wisconsin
Leo B. House
1981, Open-File Report 81-1192
This study documents Streamflow, temperature, and water-quality conditions of Bridge Creek at Augusta, Wisconsin, and evaluates the potential effects of a proposed small impoundment on the creek. The effects are of concern to the Wisconsin Department of Natural Resources because the stream is a Class II trout stream. Average daily Streamflow,...
U.S. Geological Survey reports on the water resources of Florida, 1886-1980
Nevin Douglas Hoy, James D. Simmons, Maude Claiborne
1981, Open-File Report 81-816
The U.S. Geological Survey has been making investigations of the water resources of Florida since the latter part of the 19th century. The earlier work consisted mainly of data collection at a few spring and river sites at intermittent intervals with the exception of a statewide ground-water study made during...
Ground-water data for Michigan, 1980
G.C. Huffman
1981, Open-File Report 81-811
The purpose of this report is to make available the 1980 records of water levels and related data for the principal aquifers of the State. This report is written for municipalities, industries, institutions, consultants, drillers, hydrologists and other people interested in the ground-water resources....
Low-flow frequency data for selected stream gaging stations in Florida
G.H. Hughes
1981, Open-File Report 81-69
This report contains tables of low-flow frequency data for 161 stream-gaging stations in Florida. The selected stations represent those having suitable flow records spanning 7 or more years. Flow values representing the annual minimum average flow for selected periods ranging from 1 to 183 days are presented for recurrence intervals...
Hydrogeology of well-field areas near Tampa, Florida; Phase I, development and documentation of a two-dimensional finite-difference model for simulation of steady-state ground-water flow
C. B. Hutchinson, Dale M. Johnson, James M. Gerhart
1981, Open-File Report 81-630
A two-dimensional finite-difference model was developed for simulation of steady-state ground-water flow in the Floridan aquifer throughout a 932-square-mile area, which contains nine municipal well fields. The overlying surficial aquifer contains a constant-head water table and is coupled to the Floridan aquifer by a leakage term that represents flow through...
A 10-year plan to study the aquifer system of Indian Wells Valley, California
Paul Lipinski, Darwin D. Knochenmus
1981, Open-File Report 81-404
Water needs of the population of Indian Wells Valley, Calif., must be met through further development of ground-water resources. Studies show that annual ground-water pumpage there has increased since 1945 and has exceeded mean annual recharge since 1966. Continued and increased stress on the aquifer system of the valley is...
Hydrologic monitoring in the coal fields of central Utah, August 1978-September 1979
Gregory C. Lines, Gerald G. Plantz
1981, Open-File Report 81-138
Surface-water quantity and quality were observed at 12 gaging stations downstream from mined and lease areas in the Wasatch Plateau, Book Cliff's, and Emery coal fields in central Utah. Measurements of base flow were made at 52 additional sites in the region. The report describes the hydrologic setting of this...
