Geological Survey open-file reports of Alaska indexed by quadrangle
Edward Huntington Cobb
1974, Open-File Report 74-7
The Geological Survey places in open files reports and maps that are preliminary or ephemeral in nature, are of interest to a small audience only, or consist of masses of essentially raw data. These reports and maps are available to the public and may be consulted at various Geological Survey...
Hydrology of the abandoned coal mines in the Wyoming Valley, Pennsylvania
Jerrald R. Hollowell
1974, Open-File Report 74-237
Mine-water discharge, into the Susquehanna River degrades the river's quality during periods of low flow to a point critical for subsistence of aquatic life. To determine what measures are required to provide a better quality mine-water discharge in the Wyoming Valley, mine hydrology and mine-water quality are related to mine-pool...
Average composition of agriculture soils in Missouri counties
Ronald R. Tidball
1974, Open-File Report 74-66
Samples of agricultural soils were collected extensively throughout the State of Missouri for the purpose of evaluating the distribution of elements in soils of the State. Only soils used for agricultural purposes during the year 1970 or before were sampled. It is recognized that these soils may be altered chemically...
Geological Survey published reports on Alaska, 1915-1939, indexed by quadrangle
Edward Huntington Cobb
1974, Open-File Report 74-335
Geological Survey reports published as Professional Papers, Bulletins, Water Supply Papers, and Circulars are listed by the quadrangles (scale 1:250,000) into which Alaska has been divided for topographic mapping (p. 3). This index does not include reports that deal only with administrative matters or that were placed in open files...
Storage of low-level radioactive wastes in the ground; hydrogeologic and hydrochemical factors
Stavros Stefanu Papadopulos, Isaac Judah Winograd
1974, Open-File Report 74-344
The status of mathematical simulation techniques, as they apply to radioactive waste burial sites, is briefly reviewed, and hydrogeologic and hydrochemical data needs are listed in order of increasing difficulty and cost of acquisition. Predictive modeling, monitoring, and management of radionuclides dissolved and transported by ground water can best be...
Floods in Indiana: technical manual for estimating their magnitude and frequency
L.G. Davis
1974, Circular 710
This manual provides methods for estimating the magnitude and frequency of floods on unregulated and unurbanized streams in Indiana that drain at least 15 square miles (38.8 square kilometres). The methods provide the design engineer with a means of estimating flood frequencies without having to analyze the records at individual...
