Sediment parameters for a fine-grained sediment deposit on the southeastern New England continental shelf
Richard R. Rendigs, Michael H. Bothner, Lawrence J. Poppe
1981, Open-File Report 81-1334
An area of fine-grained sediments south of Martha's Vineyard, Massachusetts, has been interpreted as a contemporary deposit. Textural analysis of cores from this area indicates that the deposit consists of sandy to clayey silts overlying a well sorted relict sand. The maximum thickness of the fine sediments is about 6...
Summary of U.S. Geological Survey investigations and hydrologic conditions in southwest Florida for 1979
H.C. Rollins
1981, Open-File Report 81-78
This report summarizes the hydrologic setting and the water-resources investigations in the Southwest Florida Water management District performed by the U.S. Geological Survey, Water Resources Division, for fiscal year 1979. Hydrologic conditions in southwest Florida are described and illustrated by hydrographs of selected surface-water, ground-water, and lake-stage data-collection sites. In...
Dissolved-oxygen and algal conditions in selected locations of the Willamette River basin, Oregon
F. A. Rinella, S. W. McKenzie, S.A. Wille
1981, Open-File Report 81-529
During July and August 1978, the U.S. Geological Survey, in cooperation with the Oregon Department of Enviromental Quality, made three intensive river-quality dissolved-oxygen studies in the upper Willamette River basin. Two studies were made on the upper Willamette River and one was made on the Santiam River, a Willamette River...
Geochemistry of spring water, southeastern Uinta Basin, Utah and Colorado
Briant A. Kimball
1981, Water Supply Paper 2074
The chemical quality of water in the southeastern Uinta Basin, Utah and Colorado, is important to the future development of the abundant oil-shale resources of the area. This report examines the observed changes in chemistry as water circulates in both shallow and deep ground-water systems. Mass-balance and mass- transfer calculations...
Dendroclimatic estimates of a drought index for northern Virginia
Larry J. Puckett
1981, Water Supply Paper 2080
A 230-year record of the Palmer drought-severity index (PDSI) was estimated for northern Virginia from variations in widths of tree rings. Increment cores were extracted from eastern hemlock, Tsuga canadensis (L.) Carr., at three locations in northern Virginia. Measurements of annual growth increments were made and converted to standardized indices...
Tracing ground-water movement by using the stable isotopes of oxygen and hydrogen, upper Penitencia Creek alluvial fan, Santa Clara Valley, California
K. S. Muir, Tyler B. Coplen
1981, Water Supply Paper 2075
Starting in 1965 the Santa Clara Valley Water District began importing about i00,000 acre-feet per year of northern California water. About one-half of this water was used to artificially recharge the Upper Penitencia Creek alluvial fan in Santa Clara Valley. In order to determine the relative amounts of local ground...
