Long-range plans for hydrologic investigations in New Mexico
H. L. Case III, G. E. Welder
1983, Open-File Report 83-696
Objectives of the hydrologic-data-collection projects presented in this report include continuing to identify future data needs; conducting an analysis of the water-quality, ground-water, and surface-water observation networks; and entering all available current and historical hydrologic data into the U.S. Geological Survey Water Data Storage and Retrieval System (WATSTORE). Objectives of...
Hydrologic data for the Great and Denbow heaths in eastern Maine, October 1980 through September 1981
Wallace J. Nichols, J.A. Smath, J.T. Adamik
1983, Open-File Report 83-866
Hydrologic data collected on the Great and Denbow Heaths, Maine, include precipitation, pan evaporation, air temperatures, streamflow, groundwater levels, and water quality constituents. These data were collected for a peat bog hydrology study conducted in cooperation with the Maine Geological Survey. The data network consisted of climate information from three...
Instrumentation for measuring and recording streamflow data at river-control structures
Instrument Development Laboratory
1983, Open-File Report 83-872
Instrumentation was developed in the mid to late 60 's to resolve the dilemma of intolerably high percentages of missing streamflow records on certain large and highly controlled streams in industrialized parts of the United States. Analysis of the field situation at specific problem sites quickly suggested that conventional stream...
A hydrogeochemical survey in east-central Nevada
John B. McHugh, W. Roger Miller, Walter H. Ficklin
1983, Open-File Report 83-286
A hydrogeochemical survey utilizing waters from springs and wells was conducted in east-central Nevada. None of the trace elements commonly associated with mineralization were found to be highly anomalous in the study area. Slightly anomalous values for some elements were found in the southern valleys of the study area and...
Hydrologic data for the Great and Denbow heaths in eastern Maine, October 1981 through October 1982
Wallace J. Nichols
1983, Open-File Report 83-865
Hydrologic data collected on the Great and Denbow Heaths, Maine, include precipitation, pan evaporation, air temperatures, streamflow, and ground water levels. These data were collected for a peat bog hydrology study conducted in cooperation with the Maine Geological Survey. The data network consisted of climate information from three rain gages,...
Availability and chemical quality of water from surficial aquifers in Southwest Minnesota
D. G. Adolphson
1983, Water-Resources Investigations Report 83-4030
The principal surficial aquifers in southwest Minnesota consist of outwash and alluvium material deposited in river valleys. The largest and most productive of these aquifers occupy the valleys of the Cottonwood, Des Moines, Redwood, and Rock Rivers and of tributaries to the Big Sioux River. Minor aquifers, adequate only for...
Streamflow and suspended-sediment transport in Garvin Brook, Winona County, southeastern Minnesota: Hydrologic data for 1982
G. A. Payne
1983, Open-File Report 83-212
Streamflow and suspended-sediment-transport data were collected in Garvin Brook watershed in Winona County, southeastern Minnesota, during 1982. The data collection was part of a study to determine the effectiveness of agricultural best-management practices designed to improve rural water quality. The study is part of a Rural Clean Water Program demonstration...
$ANBA; a rapid, combined data acquisition and correction program for the SEMQ electron microprobe
James J. McGee
1983, Open-File Report 83-817
$ANBA is a program developed for rapid data acquisition and correction on an automated SEMQ electron microprobe. The program provides increased analytical speed and reduced disk read/write operations compared with the manufacturer's software, resulting in a doubling of analytical throughput. In addition, the program provides enhanced analytical features such as...
Specifications for updating USGS land use and land cover maps
Valerie A. Milazzo
1983, Open-File Report 83-116
To meet the increasing demands for up-to-date land use and land cover information, a primary goal of the U.S. Geological Survey's (USGS) national land use and land cover mapping program is to provide for periodic updating of maps and data in a timely and uniform manner. The technical specifications for...
Hydraulic considerations in sampling the unsaturated zone with inclined gravity lysimeters
E. T. Oaksford
1983, Water-Resources Investigations Report 83-4005
Inclined gravity lysimeters as deep as 5.39 meters below land surface designed for sampling soil water in coarse sand under continuous ponding conditions, were shown to be capable of collecting 10 liters per hour at an infiltration rate of 0.5 meter per hour. This represents a capture efficiency of approximately...
