Soil moisture in the Black River Basin, New York, during 1972-73: International Field Year for the Great Lakes (IFYGL)
William N. Embree
1976, Open-File Report 76-543
Soil-moisture data were collected and analyzed to provide an estimate of the quantity of water in temporary storage in the Black River Basin, New York, during the International Field Year for the Great Lakes (IFYGL) (April 1, 1972 to March 31, 1973). A portable neutron logger was used to record...

Documentation of programs that compute 1) quasi-static tilts produced by an expanding dislocation loop in an elastic and viscoelastic material, and 2) surface shear stresses, strains, and shear displacements produced by screw dislocations in a vertical slab with modulus contrast
Stuart McHugh
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...

Flood-frequency analysis for small natural streams in Georgia
Harold G. Golden, McGlone Price
1976, Open-File Report 76-511
Flood information from 104 project basins (0.1 to 20 square miles) and data available from 170 larger basins (20 to 1,500 square miles) are analyzed to provide planners and designers with relations for estimating the magnitude and frequency of flood-peak discharges on small natural streams in Georgia. More than 90...

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...
