Determination of reaeration coefficients for Ohio streams
Janet Hren
1984, Water-Resources Investigations Report 84-4139
The hydrocarbon-gas tracer technique was used to determine reaeration coefficients on 30 reaches of Ohio streams. The studies were done from September 1979 through August 1982 to determine the reaeration coefficients for the individual reaches and to develop general equation that could be used to estimate the coefficients. Multiple linear...

Leo B. House
1984, Water-Resources Investigations Report 84-4051
A digital hydrologic model was used to simulate the effects of future residential development on pond inflow volumes and resulting water levels of three ponds in Middleton, Wisconsin. The model computed the daily water budget and the resulting water level for each pond. The results of the model calibration are...
Channel changes of Powder River between Moorhead and Broadus, Montana, 1939-1978
H. A. Martinson
1984, Water-Resources Investigations Report 83-4128

Contemporaneous daily mean and peak discharge records from Moorhead provide the...
Statistical models for estimating flow characteristics of Michigan streams
D. J. Holtschlag, H.M. Croskey
1984, Water-Resources Investigations Report 84-4207
Multiple-regression equations were developed to estimate flow characteristics at ungaged sites. Several readily measureable basin characteristics and an areal adjustment factor are required in the equations. Equations have been prepared to estimate mean and mean monthly flow, flow duration, low flow, peak flow, and flood volume. The precision of the...

1984, Water-Resources Investigations Report 84-4136
According to U.S. Geological Survey records, a report prepared by R. Gonfiantini summarizing the findings and recommendations of the 1983 Advisory Group Meeting on Stable Isotope Reference Samples for Geochemical and Hydrologic Investigations held in Vienna does not accurately represent the consultants ' consensus on three important points. The consultants...
Cost effectiveness of the U.S. Geological Survey's stream-gaging program in Illinois
D. M. Mades, K. A. Oberg
1984, Water-Resources Investigations Report 84-4123
Data uses and funding sources were identified for 138 continuous-record discharge-gaging stations currently (1983) operated as part of the stream-gaging program in Illinois. Streamflow data from five of those stations are used only for regional hydrology studies. Most streamflow data are used for defining regional hydrology, defining rainfall-runoff relations, flood...

1984, Water-Resources Investigations Report 84-4248
Test well UE-25pNo1 was drilled in cooperation with the U.S. Department of Energy in the southwestern part of the Nevada Test Site, for investigations related to the isolation of high-level nuclear wastes. Rocks penetrated in the well are predominantly ash-flow tuffs of Tertiary age to a depth of 1,244 meters...

S. N. Luoma, P. V. Cascos, R. M. Dagovitz
1984, Water-Resources Investigations Report 84-4170
A 5-month partial study (February to July 1983) was completed in Suisun Bay, a shallow embayment of San Francisco Bay, Calif., to determine characteristic heavy metal concentrations present in sediments and organisms (Corbicula clams) prior to possible discharge of San Luis Drain irrigation tile return water. Preliminary results show sediments...
A reconnaissance of the water resources of the Shoalwater Bay Indian Reservation and adjacent areas, Pacific County, Washington, 1978-1979
W. E. Lum
1984, Water-Resources Investigations Report 83-4165
A 1978-79 reconnaissance of the quantity and quality of water in the Shoalwater Bay Indian Reservation yielded information needed by the Shoalwater Bay Indian Tribe to plan future use of these resources. Ground water from the local artesian aquifer is suitable for most uses and it is estimated that yield...
Effects of surface coal-mine reclamation on stream quality in a small watershed near Nelsonville, southeastern Ohio
S. M. Hindall
1984, Water-Resources Investigations Report 84-4179
Abandoned surface coal mines in southeastern Ohio have caused degradation of the area's water resources. A study began in 1981 to determine the effects of abandoned-mine reclamation on water quality in the 'Yost tract' near Nelsonville, Ohio. Data on streamflow, water quality, and sedimentation were collected in Yost Run before,...
Low-flow transport models for conservative and sorbed solutes — Uvas Creek, near Morgan Hill, California
A. P. Jackman, R. A. Walters, V. C. Kennedy
1984, Water-Resources Investigations Report 84-4041
Models describing low-flow transport of conservative (nonreactive) and reactive solutes, which adsorb on the streambed, are developed and tested. Temporary storage within the bed plays an important role in solute movement. Three different models of bed-storage processes are developed for conservative solutes. One model assumes the bed is a well-mixed,...
Availability of ground water from the alluvial aquifer on the Nisqually Indian Reservation, Washington
W. E. Lum II
1984, Water-Resources Investigations Report 83-4185
A digital model using finite-difference techniques was constructed to simulate ground-water flow in an alluvial aquifer on the Nisqually Indian Reservation. The maximum long-term rate of pumping from individual wells, based on available data, is about 0.75 cubic feet per second (340 gallons per minute). Data on the extent, hydraulic...
Floods of August 7-8, 1979, in Chautauqua County, New York, with hydraulic analysis of Canadaway Creek in the village of Fredonia
Richard Lumia, W. H. Johnston
1984, Water-Resources Investigations Report 83-4211
Extensive flooding of streams in Chautauqua County, N.Y., on August 7-8, 1979, after severe thunderstorms, resulted in one death and millions of dollars worth of property damage. Severe flooding was reported on Canadaway Creek in Fredonia, where the peak discharge was computed to be 12,000 cubic feet per second. The...
Estimates of dissolved and suspended substance yield of stream basins in Michigan
T. R. Cummings
1984, Water-Resources Investigations Report 83-4288
Water-quality data collected at 20 stations in Michigan were used to develop regression equations relating loads of dissolved and suspended substances to discharge. These equations and mean daily discharge were used to estimate long-term loads, which then were converted to estimates of drainage basin yields. These yields were compared to...
