Preliminary delineation and description of the regional aquifers of Tennessee -- Highland Rim aquifer system
J. V. Brahana, M. W. Bradley
1986, Water-Resources Investigations Report 82-4054
The Highland Rim aquifer system in Tennessee is primarily composed of Mississippian carbonates and occurs west of the Valley and Ridge Province. It crops out in the Highland Rim and the Sequatchie Valley. It has been removed by erosion from the Central Basin. Groundwater in the Highland Rim aquifer system...
Theoretical technique for predicting the cumulative impact of iron and manganese oxidation in streams receiving discharge from coal mines
Keith E. Bobay
1986, Water-Resources Investigations Report 86-4039
Two U.S. Geological Survey computer programs are modified and linked to predict the cumulative impact of iron and manganese oxidation in coal-mine discharge water on the dissolved chemical quality of a receiving stream. The coupled programs calculate the changes in dissolved iron, dissolved manganese, and dissolved oxygen concentrations; alkalinity; and,...
The SALT NORM : a quantitative chemical-mineralogical characterization of natural waters
Marc W. Bodine Jr., Blair F. Jones
1986, Water-Resources Investigations Report 86-4086
The new computer program SNORM calculates the salt norm from the chemical composition of a natural water. The salt norm is the quantitative ideal equilibrium assemblage that would crystallize if the water evaporated to dryness at 25 C and 1 bar pressure under atmospheric partial pressure of CO2. SNORM proportions...
Rock riprap design for protection of stream channels near highway structures; Volume 2, Evaluation of Riprap design procedures
J. C. Blodgett, C.E. McConaughy
1986, Water-Resources Investigations Report 86-4128
In volume 2, seven procedures now being used for design of rock riprap installations were evaluated using data from 26 field sites. Four basic types of riprap failures were identified: Particle erosion, translational slide, modified slump, and slump. Factors associated with riprap failure include stone size , bank side slope,...
Preliminary delineation and description of the regional aquifers of Tennessee– The Cretaceous aquifer system of west-Tennessee
J. V. Brahana, Dolores Mulderink, M. W. Bradley
1986, Water-Resources Investigations Report 83-4039
The Cretaceous aquifer in Tennessee is composed of sand and clay of Cretaceous age. The aquifer occurs in west Tennessee from the Mississippi River east to the Tennessee River. Groundwater in the Cretaceous aquifer is recharged at outcrops and through overlying permeable deposits. The overlying Porter 's Creek clay acts...
A reconnaissance water-quality appraisal of the Fountain Creek alluvial aquifer between Colorado Springs and Pueblo, Colorado, including trace elements and organic constituents
Doug Cain, Patrick Edelmann
1986, Water-Resources Investigations Report 86-4085
This report describes the hydrology and chemical quality of water in the stream-aquifer system along Fountain Creek and relates groundwater quality to land use, water use, and wastewater discharges. The alluvial aquifer, which is underlain by shale bedrock, is transmissive, extensively pumped, and primarily is recharged by Fountain Creek and...
Rock riprap design for protection of stream channels near highway structures; Volume 1, Hydraulic characteristics of open channels
J. C. Blodgett
1986, Water-Resources Investigations Report 86-4127
Volume I discusses the hydraulic and channel properties of streams, based on data from several hundred sites. Streamflow and geomorphic data have been collected and developed to indicate the range in hydraulic factors typical of open channels , to assist design, maintenance, and construction engineers in preparing rock riprap bank...
Water quality of Rhode Island streams
J. C. Briggs, J.S. Feiffer
1986, Water-Resources Investigations Report 84-4367
Water quality data collected from November 1979 through September 1983 at five stream stations within Rhode Island and one in Massachusetts show that concentrations of the common constituents were low. Mean water hardness at all sites was in the ' soft ' category. Sodium concentrations were less than 20 mg/L...
Flow testing of the Newberry 2 research drillhole, Newberry volcano, Oregon
S. E. Ingebritsen, W.W. Carothers, Robert H. Mariner, J.S. Gudmundsson, E.A. Sammel
1986, Water-Resources Investigations Report 86-4133
A 20 hour flow test of the Newberry 2 research drillhole at Newberry Volcano produced about 33,000 kilograms of fluid. The flow rate declined from about 0.8 kilograms per sec to less than 0.3 kilograms per sec during the course of the test. The mass ratio of liquid water to...
Quality of stormwater runoff in the Blue River basin, Missouri and Kansas, July-October 1981 and April-July 1982
D. W. Blevins
1986, Water-Resources Investigations Report 84-4226
Stormwater-runoff sampling was done at three mainstem stations on the Blue River, Missouri, and three stations on urban tributaries. Concentrations of lead, iron, manganese, zinc, and ammonia nitrogen consistently exceeded Missouri water-quality standards. Many constituents were significantly correlated with large concentrations of suspended sediment from the agricultural areas in the...
Sediment discharge in the Colorado River near De Beque, Colorado
D. L. Butler
1986, Water-Resources Investigations Report 85-4266
A study was conducted to determine annual-sediment discharge at the site of a proposed reservoir on the Colorado River at Una, located 3 miles upstream from De Beque, Colorado. Eleven suspended sediment samples were collected during 1984 at the De Beque bridge. These data were combined with suspended sediment data...
Regionalization of winter low-flow characteristics of Tennessee streams
R.H. Bingham
1986, Water-Resources Investigations Report 86-4007
Procedures were developed for estimating winter (December-April) low flows at ungaged stream sites in Tennessee based on surface geology and drainage area size. One set of equations applies to West Tennessee streams, and another set applies to Middle and East Tennessee streams. The equations do not apply to streams where...
Regionalization of low-flow characteristics of Tennessee streams
R.H. Bingham
1986, Water-Resources Investigations Report 85-4191
Procedures for estimating 3-day 2-year, 3-day 10-year, 3-day 20-year, and 7-day 10-year low flows at ungaged stream sites in Tennessee are based on surface geology and drainage area size. One set of equations applies to west Tennessee streams, and another set applies to central and east Tennessee streams. The equations...
