Water-quality study of a reach of the Merced River in Yosemite National Park and vicinity, California, April 1973 through September 1974
Ray J. Hoffman, Alex E. Dong, Gail L. Keeter
1976, Open-File Report 76-326
A 25-mile reach of the Merced River was studied to provide the U.S. National Park Service with water-quality data prior to the operation of a new sewage treatment plant. Water-quality variables investigated were discharge, temperature, major chemical constituents, selected trace metals, specific conductance, suspended sediment, turbidity, dissolved oxygen, pH ,...
Reconnaissance of ground-water resources of the Squaxin Island Indian Reservation, Washington
W. E. Lum II, Kenneth Lyle Walters
1976, Open-File Report 76-382
A supply of fresh ground water for the Squaxin Island Indian Reservation exists in saturated deposits underlying the 3.09-square-mile island, whereas surface-water supplies are practically nonexistent. Four test wells tapped a water-hearing zone of sand and gravel and had yields ranging from 27 to 170 gallons per minute, with drawdowns...
Low-Flow Characteristics and Mean Annual Discharge of North Branch Manitowoc River at Potter, Wisconsin
B. K. Holmstrom
1976, Open-File Report 76-204
The low-flow characteristics presented in this report are the annual minimum 7-day mean flows at the 2-year recurrence interval and 10-year recurrence interval. They were determined just downstream from the confluence of the three streams forming the North Branch Manitowoc River and, based on natural-flow conditions, are 0.0 cubic foot...

Floods in Pennsylvania: A manual for estimation of their magnitude and frequency
Herbert N. Flippo Jr.
1976, Open-File Report 76-391
Regression equations are provided for estimation of flood magnitude and frequency on unregulated and unurbanized streams in Pennsylvania. Frequency-discharge profiles are shown for regulated reaches on eleven major streams. These regression equations and discharge profiles enable the design engineer to estimate flood-frequency characteristics for almost all streams that drain more...

Flood-Plain Delineation for Cameron Run Basin Water-surface profiles of the 25-, 50-, and 100-year recurrence interval discharges have been computed for all streams and reaches of channels in Fairfax County, Virginia, having a drainage area greater than 1 square mile except for Dogue Creek, Little Hunting Creek, and that part...

A preliminary evaluation of selected earthquake-related geologic hazards in the Kenai Lowland, Alaska
Russell G. Tysdal
1976, Open-File Report 76-270
Several major faults exist beneath the Kenai Lowland, and others may be inferred. No surface evidence was found to indicate that any of the faults have been active in Holocene time. The sparse shallow seismicity thus far recorded does not correlate with known faults, nor does it define linear trends...

1976, Open-File Report 76-731
Seismic wave velocities (compressional and shear) are important parameters for determining the seismic response characteristics of various geologic units when subjected to strong earthquake ground shaking.Seismic velocities of various units often show a strong correlation with the amounts of damage following large earthquakes and have been used as a basis...

Ground-water resources in the Lompoc area, Santa Barbara County, California
G.A. Miller
1976, Open-File Report 76-183
Water supplies in the Lompoc plain are pumped from highly permeable gravel and sand, which make up the main water-bearing zone. The history of ground-water quality in the Lompoc area shows little change in the Lompoc upland and the Lompoc terrace, but an increase in the concentration of dissolved solids...

Urban development on or adjacent to the recharge zone of the Edwards aquifer is causing concern about the possible pollution of ground water in the aquifer, which is the principal source of water supply for the San Antonio area. Water-quality data for many wells and springs and for selected sites...

1976, Open-File Report 76-484
The material in this report can be grouped into two categories: 1) programs that compute tilts produced by a vertically oriented expanding rectangular dislocation loop in an elastic or viscoelastic material and 2) programs that compute the shear stresses, strains, and shear displacements in a three-phase half-space (i.e. a half-space...
