F.P. Haeni, Elinor H. Handman
1978, Water-Resources Investigations Report 78-77
A hydrologic analysis of the stratified drift in Newtown, Conn., based on available data, test drilling, seismic refraction profiling, and the stream-aquifer connection was performed using a digital computer model. Simulated pumping indicates that a total of 4.0 million gallons of water per day (Mgal/d) can be withdrawn from the...
Isotopic and chemical data from carbonate cements in surface rocks over and near four Oklahoma oil fields
Mitchell E. Henry, Terrence J. Donovan
1978, Open-File Report 78-927
Carbonate cements in outcropping sandstones overlying the Doyle, Fox-Graham, Velma, and part of Wheeler oil fields, Oklahoma, were analyzed for their C13/ 12, 018/016, iron, and manganese compositions. The peculiar areal distribution of the values obtained is interpreted to be the direct result of hydrocarbon microseepage....

Unsteady solute-transport simulation in streamflow using a finite-difference model
Larry F. Land
1978, Water-Resources Investigations Report 78-18
This report documents a rather simple, general purpose, one-dimensional, one-parameter, mass-transport model for field use. The model assumes a well-mixed conservative solute that may be coming from an unsteady source and is moving in unsteady streamflow. The quantity of solute being transported is in the units of concentration. Results are...
Quantitative hydrogeology of the Upper Republican Natural Resources District, southwest Nebraska
Eric G. Lappala
1978, Water-Resources Investigations Report 78-38
Ground-water use for irrigation from the Ogallala Formation }'as in-creased rapidly in the Upper Republican Natural Resources District in southwest Nebraska. Water levels declined as much as 16 feet between 1952 and 1975. Discharge of the aquifer to streams was reduced by as much as 19 percent between 1967 and...
An analysis of stream temperatures, Green River Basin, Wyoming
H. W. Lowham
1978, Water-Resources Investigations Report 78-13
A method for estimating temperatures of streams in the Green River basin, Wyoming, utilizes a regional model for estimating mean daily temperatures of streams at unmeasured sites. The regional model was developed by describing annual temperature patterns at 43 measured sites and by applying the harmonic function T = M...
Flood profiles for Cypress Creek, west-central Florida
W. R. Murphy Jr.
1978, Water-Resources Investigations Report 78-8
Flood profiles are included for selected recurrence-interval floods in west-central Florida for a 27-mile reach of Cypress Creek, for a 4-mile tributary reach, and for a 1.2-mile distributary reach. The procedure for constructing flood profiles is based on flood heights computed in a step-backwater analysis using the following data: 2-,...
Ages of flow units in the far eastern lunar maria based on crater density
Joseph M. Boyce
1978, Open-File Report 78-879
The distribution of major geologic units of uniform relative age exposed in the far eastern maria (i.e., Mare Marginis, Mare Smythii, and Mare Crisium) and Mare Humorum was compiled in map form on the basis of a crater density mapping technique. Correlation of crater densities and radiometric ages of Apollo...

Lithologic and borehole geophysical data, Green Swamp area, Florida
Hayes F. Grubb, John W. Chappelear, James A. Miller
1978, Open-File Report 78-574
Continuous unconsolidated cores were obtained at 74 sites in the Green Swamp are to evaluate the potential for downward leakage to the Floridian aquifer. Depth of the core holes ranged from 21 to 227 feet and averaged about 87 feet., Lithology was determined by microscopic examination of the core from...
Sediment transport by the White River into Mud Mountain Reservoir: Washington, June 1974-June 1976
Leonard M. Nelson
1978, Water-Resources Investigations Report 78-133
This reconnaissance evaluation of the sediment transport by the White River into the Mud Mountain Reservoir, in Washington, during the period June 1974-June 1976 showed that the river transported 430,000 tons of suspended sediment into the reservoir during the first year of the study and 1,400,000 tons in the second...
Technique for estimating magnitude and frequency of floods in Virginia
Earley M. Miller
1978, Water-Resources Investigations Report 78-5
A technique is presented for estimating the magnitude and frequency of floods in Virginia. For 299 gaged sites, the magnitudes of floods having recurrence intervals of 2 to 100 years are provided in tables. For ungaged sites, regression relations are presented that allow the estimation of flood magnitudes based on...

Guidelines for the use of structural versus regression analysis in geomorphic studies
W. R. Osterkamp, Jesse M. McNellis, Paul Robert Jordan
1978, Water-Resources Investigations Report 78-135
Simple-regression and structural analysis are similar methods of developing a linear relation from a bivariant group of data. Regression analysis is a useful curve-fitting technique, but often is misapplied to geomorphic data sets. When error components can be identified for both variables, the statistical technique of structural analysis is preferred....
Nitrogen, phosphorus, organic carbon, and biochemical oxygen demand: in Florida surface waters, 1972
Matthew I. Kaufman, J.E. Dysart
1978, Water-Resources Investigations Report 78-43
Water samples were collected during spring and autumn 1972 from about 100 surface-water sites in Florida. The samples were analyzed for the plant nutrients, nitrogen and phosphorus. In most waters, nitrogen concentrations are less than 2.0 milligrams per liter as nitrogen, and organic nitrogen is dominant. Median total nitrogen concentration...
