The environment of south-central Tunisia as observed on Landsat scene 206/036
M. J. Grolier, P.A. Schultejann
1982, Open-File Report 82-130
One Landsat image in south-central Tunisia was analyzed to demonstrate the application of remote-sensing technology to regional development. A preliminary analysis included I) major landscape features; 2) gypsum-encrusted soils; and 3) phosphate-bearing beds exposed in the Gafsa mining district. The products specifically used for this report include: 1) A false-color...

1982, IMAP 1311
The rocks and deposits within the Wenatchee quadrangle can be grouped into six generalized units: (1) Precambrian(?) Swakane Biotite Gneiss in the northeastern part of the quadrangle and the probable Jurassic low-grade metamorphic suite, mostly composed of the Easton Schist, in the southwestern part; (2) the Mesozoic Ingalls Tectonic Complex;...
Small-stream flood investigations in Minnesota, October 1958 to September 1980
Kurt T. Gunard, C.J. Smith
1982, Open-File Report 82-433
An investigation of flood flows from small drainage basins in Minnesota is being made to aid in the design of bridges, culverts and other highway drainage structures. Results of the investigation provide peak-flow data on streams generally with drainage areas less than 200 square miles, placing particular emphasis on those...

The determination of total volatiles in rocks by loss-on-fusion
V.G. Mossotti, B. King
1982, Open-File Report 82-587
A fast and accurate technique has been developed for the determination of the total volatile content of rocks. The loss on fusion (LOF) results are comparable to the conventional time-consuming wet-chemical procedure but require no additional effort or cost when conducted as part of the usual sample preparation procedure for...
Water resources of Borrego Valley and vicinity, California: Phase 1— Definition of geologic and hydrologic characteristics of the basin
W. R. Moyle
1982, Open-File Report 82-855
This report is phase 1 of a 3-phase study and includes information needed to build a digital hydrologic model of Borrego Valley. It includes sources and amounts of recharge water to the basin, areas of water withdrawal, total ground water in storage at steady-state conditions (1945), net ground-water depletion, grid...

An index of geophysical well logging in Virginia by the U.S. Geological Survey
M. Patrick Mulheren, J. D. Larson, Herbert T. Hopkins
1982, Open-File Report 82-432
Geophysical logs have been obtained in more than 170 wells in Virginia by the U.S. Geological Survey since 1968. These logs include natural gamma, electric, caliper, temperature, fluid conductivity, and fluid velocity. Most of the logs are for wells in the Coastal Plain Province of eastern Virginia. Geophysical logs aid...

1982, Open-File Report 82-151
The National Water Data Exchange (NAWDEX), formally established in January 1976, is a national confederation of water-oriented organizations working together to improve access to water data. Its primary objective is to assist users of water data in the identification, location, and acquisition of needed water data or water-related data. NAWDEX...
Baseline water-quality data for sand-plain aquifers in Hubbard, Morrison, Otter Tail, and Wadena counties, Minnesota
C. F. Myette
1982, Open-File Report 82-909
Tapping the surficial sand-plain aquifers in west-central Minnesota has raised the possibility for degradation of water quality. The sand-plain areas are generally overlain by sandy soils that permit rapid infiltration of precipitation and, possibly, of surface contaminants. One hundred twenty-five wells were sampled in Hubbard, Morrison, Otter Tail, and Wadena...

Dissolved solids and sodium in water from the High Plains aquifer in parts of Colorado, Kansas, Nebraska, New Mexico, Oklahoma, South Dakota, Texas, and Wyoming
Noel C. Krothe, Joseph W. Oliver, John B. Weeks
1982, Hydrologic Atlas 658
In 1978, the U.S. Geological Survey initiated a 5-year study of the High Plains regional aquifer to provide: (1) Hydrologic information needed to evaluate the effects of continued ground-water development; and (2) computer models to predict aquifer response to changes in ground-water development. The plan of study for the High...
Perennial-streamflow characteristics related to channel geometry and sediment in Missouri River basin
W. R. Osterkamp, E. R. Hedman
1982, Professional Paper 1242
Geometry, channel-sediment, and discharge data were collected and compiled from 252 streamflow-gaging stations in the Missouri River basin. The sites represent the complete ranges of hydrologic and geologic conditions found in the basin. The data were analyzed by computer to yield equations relating various discharge characteristics to variables of channel...
Effects of flooding upon woody vegetation along parts of the Potomac River flood plain
T.M. Yanosky
1982, Professional Paper 1206
A two-part study along the Potomac River flood plain near Washington, D.C., was undertaken to investigate the effects of flooding upon woody vegetation. Floods abrade bark, damage branches and canopies, and often uproot trees. The first study was of vegetation in five monumented flood-plain plots which differed in the frequency...
