Climatic data for Mirror Lake, West Thornton, New Hampshire, 1984
A.M. Sturrock, D.C. Buso, J.L. Scarborough, T. C. Winter
1986, Open-File Report 86-134
Research on the hydrology of Mirror lake, (north-central) New Hampshire includes study of evaporation. Presented here are those climatic data needed for energy-budget and mass-transfer studies, including: temperature of lake water surface; dry-bulb and wet-bulb air temperatures; wind speed at 3 levels above the water surface; and solar and atmospheric...
Summary geochemical maps for samples of rock, stream sediment, and nonmagnetic heavy-mineral concentrate, east part of the Raymond Peak Roadless Area, Alpine County, California
M.A. Chaffee
1986, Miscellaneous Field Studies Map 1365-D
The Raymond peak Roadless Area consists of two separate units.  The west part (5985), about 12 miles southwest of Markleeville in Stanislaus National Forest, has been studied separately as part of the Mokelumne Wilderness and vicinity (McKee and others, 1982).  The east part (4985) is discussed here....
Water resources of Hughes County, South Dakota
L.J. Hamilton
1986, Water-Resources Investigations Report 84-4195
Three major glacial-drift aquifers consisting of outwash sand and gravel underlie Hughes County, 784 sq mi of plains incised by the outwash-filled valley of the Missouri River in central South Dakota. Glacial-drift aquifers are recharged by more than 9,000 acre-feet of water annually and store about 1 million acre-feet of...
Hydrologic reconnaissance and summary of existing data on surface and ground-water resources in the Missouri River valley in Woodbury and Monona counties, Iowa, 1985
R.C. Buchmiller
1986, Open-File Report 86-144
A hydrologic reconnaissance of the Missouri River valley in western Iowa was begun in 1985. The study area is about 400 sq mi of Missouri River flood plain used mainly for agricultural purposes and is located mostly in parts of Woodbury and Monona Counties, Iowa. The reconnaissance was conducted to...
Ground-water levels in Alaska, water year 1983
J.O. Brunett
1986, Open-File Report 86-56
Groundwater level data in Alaska are summarized for the 1983 water year for observation wells at which levels are either recorded continuously or measured intermittently. For wells at which water levels are measured semi-annually, 10-year summaries are presented. Water levels for 153 observation wells are shown on graphs and locations...
Measurement of scour-depth near bridge piers
J. V. Skinner
1986, Water-Resources Investigations Report 85-4106
River-bed scour is a major source of damage to bridge piers and bridge abutments. When scour depth exceeds design limits, the supporting material around the footings is washed away and the structure becomes unstable. Equations for predicting scour-depth show a significant lack of agreement so portable equipment for measuring scour...
The Conterminous United States Mineral Assessment Program; background information to accompany folio of geologic, geochemical, geophysical, remote sensing, and mineral resource maps of the Wallace 1 degree x 2 degrees Quadrangle, Montana and Idaho
Jack Edward Harrison, David L. Leach, M. Dean Kleinkopf, Carl L. Long, Larry C. Rowan, Richard F. Marvin
1986, Circular 920
The Wallace 1? x 2 quadrangle in Montana and Idaho was studied by an interdisciplinary research team that included geologists, geochemists, and geophysicists, as well as specialists in isotopic dating and remote sensing. The basic data resulting from these studies, as well as the final metallic mineral resource assessments,...
Simulation of flood hydrographs for Georgia streams
Ernest J. Inman
1986, Water-Resources Investigations Report 86-4004
Flood hydrographs are needed for the design of many highway drainage structures and embankments. A method for simulating these flood hydrographs at ungaged sites in Georgia is presented in this report.The O'Donnell method was used to compute unit hydrographs and lagtimes for 355 floods at 80 gaging stations. An average...
