Preliminary results of preimpoundment water-quality studies in the Tioga River Basin, Pennsylvania and New York
Janice R. Ward
1976, Water-Resources Investigations Report 76-66
The Tioga River and its major tributaries were sampled monthly from September 1973 to May 1975. Water quality in the Tioga River is degraded by acid-mine drainage entering the stream near Blossburg from both strip- and deep-mined areas. The stream supports few species of aquatic life from Blossburg to its...

Summary appraisals of the nation's ground-water resources – California region
H. E. Thomas, D. A. Phoenix
1976, Professional Paper 813-E
Most people in the California Region live in a semiarid or arid climate, with precipitation less than the potential evapotranspiration- environments of perennial water deficiency. The deficiency becomes most onerous during the characteristically rainless summers and during recurrent droughts that may continue for 10--20 years. However, water from winter rain...

1976, Professional Paper 813-H
The Arkansas-White-Red Region, an area of265,000 square miles (6.86x1011 square metres), is characterized by diversity in geography, climate, and geology and, in turn, by diversity in water resources and water problems. The western semiarid part of the region is water deficient, that is, potential evapotranspiration exceeds precipitation. The eastern, humid part...

1976, Water-Resources Investigations Report 76-46
A study of the hydraulic characteristics of the unconsolidated glacial deposits near the city of Carmel in central Indiana shows that 21.3 million gallons per day (933 litres per second) of additional water could be withdrawn from the aquifer for an indefinite period of time . This pumpage is approximately...
Hydrologic effects of hypothetical earthquake-caused floods below Jackson Lake, northwestern Wyoming
W. R. Glass, T.N. Keefer, J.G. Rankl
1976, Water-Resources Investigations Report 76-77
Jackson Lake, located in Grand Teton National Park, Wyoming, is in an area of seismic instability. There is a possibility of flooding in the Snake River downstream from Jackson Lake Dam in the event of a severe earthquake. Hypothetical floods were routed 38 miles (61 kilometers) downstream from the dam...
Reaeration-coefficient measurements of 10 small streams in Wisconsin using radioactive tracers : with a section on the energy-dissipation model
R. Stephen Grant
1976, Water-Resources Investigations Report 76-96
Reaeration-rate coefficients were measured for 10 small streams in Wisconsin using the radioactive-tracer method. The coefficients ranged from 2.06 to 55.2 per day (base e at 25 degrees Celsius). Stream discharges ranged from 0.3 to 37.0 cubic feet per second, most discharges being less than 10 cubic feet per second....

A model for calculating effects of liquid waste disposal in deep saline aquifer
Inc. Intercomp Resource Development and Engineering
1976, Water-Resources Investigations Report 76-61
Injection of liquid industrial wastes into confined underground saline aquifers can offer a good disposal alternative from both environmental and economic considerations. One of the needs in choosing from among several disposal alternatives is a means of evaluating the influence such an injection will have on the aquifer system. This...
WATEQF; a FORTRAN IV version of WATEQ : a computer program for calculating chemical equilibrium of natural waters
Niel Plummer, Blair F. Jones, Alfred Hemingway Truesdell
1976, Water-Resources Investigations Report 76-13
WATEQF is a FORTRAN IV computer program that models the thermodynamic speciation of inorganic ions and complex species in solution for a given water analysis. The original version (WATEQ) was written in 1973 by A. H. Truesdell and B. F. Jones in Programming Language/one (PL/1.) With but a few exceptions,...
