Water resources data, Louisiana, water year 1981, volume 1. Central and northern Louisiana
Water Resources Division, U.S. Geological Survey
1981, Water Data Report LA-81-1
Water resources data for the 1981 water year for Louisiana consist of records of stage, discharge, and water quality of streams; stage, contents, and water quality of lakes and reservoirs; and water levels and water quality of ground water. This report, in three volumes, contains records for water discharge at...
Water-quality reconnaissance of Patton Lake, Jefferson County, Arkansas
James C. Petersen
1981, Open-File Report 81-806
Results of a study (summer of 1980) of pesticides, nutrients, and other water-quality characteristics of the water and bottom material of Patton Lake indicate that the lake is nutrient enriched and that several pesticides are present in the bottom material. The high pH (9.0 to 9.3) and large dissolved-oxygen concentrations...
Ground-water data for the Beryl-Enterprise area, Escalante Desert, Utah
R. W. Mower
1981, Open-File Report 81-340
This report contains a compilation of selected ground-water data for the Beryl-Enterprise area, Iron and Washington Counties, Utah. The records of the wells include such information as driller's logs, yield, drawdown, use, and temperature of the well water. There are also records of water levels in selected wells for the...
Ice-gouge data, Beaufort Sea, Alaska, 1972-1980
Douglas M. Rearic, Peter W. Barnes, Erk Reimnitz
1981, Open-File Report 81-950
The interaction of sea ice with the sea floor is an important factor affecting geologic processes on high latitude shelves. One of the most obvious forms of this interaction is the formation of furrow-like gouges or the sea floor. These gouges are caused by wind- and current-driven ice masses that...
Hydrologic effects of stress-relief fracturing in an Appalachian Valley
Granville G. Wyrick, James W. Borchers
1981, Water Supply Paper 2177
A hydrologic study at Twin Falls State Park, Wyoming County, West Virginia, was made to determine how fracture systems affect the occurrence and movement of ground water in a typical valley of the Appalachian Plateaus Physiographic Province. Twin Falls was selected because it is generally unaffected by factors that would...
Water resources of the Clarion River and Redbank Creek basins, northwestern Pennsylvania
Theodore F. Buckwalter, C.H. Dodge, G. R. Schiner, H.F. Koester
1981, Open-File Report 81-70
The Clarion River and Redbank Creek basin occupy 1,280 and 545 square miles, respectively, in northwatern Pennsylvania. The area is mostly in Clerion, Elk, and Jefferson Counties and is approximately 70 miles long and 30 miles wide. All drainage is to the Allegheny River. Sedimentary...
Potentiometric map of the Cockfield Aquifer in Mississippi, fall, 1980
B. E. Wasson
1981, Open-File Report 81-1053
This potentiometric map of the Cockfield aquifer is the eleventh in a series of maps, prepared by the U.S. Geological Survey in cooperation with the Mississippi Department of Natural Resources , Bureau of Land and Water Resources, delineating the potentiometric surfaces of the major aquifers in Mississippi. In the outcrop...
Manual for leveling at gaging stations in North Carolina
N.O. Thomas, N.M. Jackson
1981, Open-File Report 81-1104
This manual was prepared to serve several purposes in the U.S. Geological Survey North Carolina District. This manual sets forth District policy as to frequency of levels, accuracy criteria, procedures for checking the datum and setting of the various types of gages, general rules to follow in establishing the original...
Erodibility of selected soils and estimates of sediment yields in the San Juan Basin, New Mexico
Rebecca M. Summer
1981, Water-Resources Investigations Report 81-44
Onsite rainfall-simulation experiments were conducted to derive field-erodibility indexes for rangeland soils and soils disturbed by mining in coal fields of northwestern New Mexico. Mean indexes on rangeland soils range from 0 grams (of detached soil) on dune soil to 121 grams on wash-transport zones. Mean field-erodibility-index values of soils...
Dissolution of sphalerite in ferric chloride solution
Huai Su
1981, Open-File Report 81-609
The dissolution of sphalerite in acidic ferric chloride solution of polished flat surfaces and of spherical particle surface was investigated. Tests were conducted on sphalerite to study rate of dissolution by the effects of stirring speed, temperature, ferric and ferrous concentrations, purity, and particle size.Kinetic investigations were conducted in a...
Annotated bibliography of remote sensing methods for monitoring desertification
A. S. Walker, Charles J. Robinove
1981, Circular 851
Remote sensing techniques are valuable for locating, assessing, and monitoring desertification. Remotely sensed data provide a permanent record of the condition of the land in a format that allows changes in land features and condition to be measured. The annotated bibliography of 118 items discusses remote sensing methods that may...
