Aerial profiling of terrain to define stream-valley geometry: study report
Mukund Desai, William A. Drohan, John W. Hursh, Glenn Mamon, Douglas G. Youmans
1976, Open-File Report 76-672
A six-month engineering analysis was performed by The Charles Stark Draper Laboratory, Inc., at the request of the U. S. Geological Survey, to investigate the suitability of an airborne instrument package based on inertial techniques to serve as the datum for a laser altimeter in a system for aerial profiling...
Water use in Mississippi, 1975
J.A. Callahan
1976, Water-Resources Investigations Report 76-125
Water use in Mississippi in 1975 amounted to 3,050 mgd (million gallons per day). The total represents pumpage of 1,130 mgd from ground-water sources and 1,920 mgd from surface-water sources. Included in the surface water pumpage are 540 mgd of brackish water from Back Bay of Biloxi. Public Supplies at...

Water-quality investigation, Salinas River, California
George A. Irwin
1976, Water-Resources Investigations Report 76-110
Concentrations of dissolved solids in the Salinas River are variable and range from 164 to 494 milligrams per liter near Bradley and from 170 to 1,090 milligrams per liter near Spreckels. Higher concentrations near Spreckels are caused mainly by sewage inflow about 150 feet (50 meters) upstream. Concentrations of nitrogen,...

Appraisal of water resources in the Hackensack River basin, New Jersey
L.D. Carswell
1976, Water-Resources Investigations Report 76-74
The Hackensack River basin, in the northern part of the New Jersey-New York metropolitan area, includes some of the most highly urbanized areas in the United States as well as a largely undeveloped 23.4 square mile area of tidal marsh referred to as the Hackensack Meadows. Bedrock in the Hackensack...
Computer applications for step-backwater and floodway analyses
James O. Shearman
1976, Open-File Report 76-499
A computer program which can be used to computer water-surface profiles for gradually varied, subcritical flow is described. Profiles are computed by the standard step-backwater method. Water-surface profiles may be obtained for both existing stream conditions and for stream conditions as modified by encroachment. The user may specify encroachment patterns...
The effects of ground-water development on the water supply in the Post Headquarters area, White Sands Missile Range, New Mexico
T. E. Kelly, Glenn A. Hearne
1976, Open-File Report 76-277
Water-level declines in the Post Headquarters area, White Sands Missile Range, N. Mex., have been accompanied by slight but progressive increases in the concentration of dissolved solids in water withdrawn from the aquifer. Projected water-level declines through 1996 are estimated from a digital simulation model to not exceed 200 feet...
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...

This report contains rainfall, runoff, and storage data collected during the 1976 water year for a 75.5 sq mi area above the stream-gaging station Little Elm Creek near Aubrey, Texas. Floodflows from 35.7 sq mi of the area are regulated by 16 floodwater-retarding structures constructed by the Soil Conservation Service....
