Analyses and description of soil samples from Mountain Lake and Peters Mountain Wilderness Study areas, Virginia and West Virginia
J. M. Motooka, Craig A. Curtis, Frank Gardner Lesure
1978, Open-File Report 78-1077-A
Semiquantitative emission spectrographic analyses for 30 elements and atomic absorption analysis for zinc on 98 soil samples are reported here in detail. Location for all samples are in Universal Transverse Mercator (UTM) coordinates. A few samples of soil developed on Lower Devonian sandstone and chert contain more barium and zinc...
Unsteady streamflow simulation using a linear implicit finite-difference model
Larry F. Land
1978, Water-Resources Investigations Report 78-59
A computer program for simulating one-dimensional subcritical, gradually varied, unsteady flow in a stream has been developed and documented. Given upstream and downstream boundary conditions and channel geometry data, roughness coefficients, stage, and discharge can be calculated anywhere within the reach as a function of time.The program uses a linear...
Water levels in artesian and nonartesian aquifers of Florida, 1975-76
Henry G. Healy
1978, Open-File Report 78-458
From May 1975 through May 1976, water levels in the Floridan aquifer through most of north and central peninsular Florida declined 2 to 4 feet, on the basis of water-level measurements in 664 wells. These 664 were selected from a network of about 2,100 observation wells for which water-level measurements...
Storm-water data for Bear Creek basin, Jackson County, Oregon 1977-78
Loren A. Wittenberg
1978, Open-File Report 79-217
Storm-water-quality samples were collected from four subbasins in the Bear Creek basin in southern Oregon. These subbasins vary in drainage size, channel slope, effective impervious area, and land use. Automatic waterquality samplers and precipitation and discharge gages were set up in each of the four subbasins. During the period October...
