Archive of water gun subbottom data collected during USGS cruise SEAX 96004, New York Bight, 1 May - 9 June 1996
Jenna C. Hill, William C. Schwab, David S. Foster
2000, Open-File Report 2000-396
Beginning in 1995, the USGS, in cooperation with the U.S Army Corps of Engineers (USACE), New York District, began a program to generate reconnaissance maps of the sea floor offshore of the New York-New Jersey metropolitan area, one of the most populated coastal regions of the United States. The goal...
Autobiography of Philip B. King
Philip Burke King
2000, Open-File Report 2000-443
Philip Burke King's interests and methods of scientific inquiry were those of a field geologist who obtains his data from the rocks exposed at the Earth's surface and from them derives inferences as to the history and behavior of the Earth. He was especially interested in the sedimentary rocks, and...
Droughts in Georgia
Nancy L. Barber, Timothy C. Stamey
2000, Open-File Report 2000-380
Droughts do not have the immediate effects of floods, but sustained droughts can cause economic stress throughout the State. The word 'drought' has various meanings, depending on a person's perspective. To a farmer, a drought is a period of moisture deficiency that affects the crops under cultivation - even two...
Flood tracking chart for the Upper San Jacinto River Basin near Houston, Texas
Dana L. Barbie
2000, Open-File Report 2000-387
The “Flood Tracking Chart for the Upper San Jacinto River Basin near Houston, Texas” can be used to track river stage and to assess flood-crest information during substantial storms. Water-surface elevation during a flood will provide emergency-response personnel, residents, and the traveling general public essential information to make informed decisions...
Regional evaluation of evapotranspiration in the Everglades
E. R. German
2000, Water-Resources Investigations Report 2000-4217
Nine sites in the Florida Everglades were selected and instrumented for collection of data necessary for evapotranspiration-determination using the Bowen-ratio energy-budget method. The sites were selected to represent the sawgrass or cattail marshes, wet prairie, and open-water areas that constitute most of the natural Everglades system. At each site, measurements...
Digital Map of Water-Level Changes in the High Plains Aquifer in Parts of Colorado, Kansas, Nebraska, New Mexico, Oklahoma, South Dakota, Texas, and Wyoming, 1980 to 1997
Brian C. Fischer, Keith M. Kollasch, Virginia L. McGuire
2000, Open-File Report 2000-96
This data set consists of digital water-level-change contours for the High Plains aquifer in the central United States, 1980 to 1997. The High Plains aquifer extends from south of 32 degrees to almost 44 degrees north latitude and from 96 degrees 30 minutes to 104 degrees west longitude....
Documentation of a computer program to simulate lake-aquifer interaction using the MODFLOW ground water flow model and the MOC3D solute-transport model
Michael L. Merritt, Leonard F. Konikow
2000, Water-Resources Investigations Report 2000-4167
Heads and flow patterns in surficial aquifers can be strongly influenced by the presence of stationary surface-water bodies (lakes) that are in direct contact, vertically and laterally, with the aquifer. Conversely, lake stages can be significantly affected by the volume of water that seeps through the lakebed that separates the...
Towards policy relevant environmental modeling: contextual validity and pragmatic models
Scott B. Miles
2000, Open-File Report 2000-401
"What makes for a good model?" In various forms, this question is a question that, undoubtedly, many people, businesses, and institutions ponder with regards to their particular domain of modeling. One particular domain that is wrestling with this question is the multidisciplinary field of environmental modeling. Examples of environmental models...
Delineation and Analysis of Uncertainty of Contributing Areas to Wells at the Southbury Training School, Southbury, Connecticut
J. Jeffrey Starn, Janet Radway Stone, John R. Mullaney
2000, Water-Resources Investigations Report 2000-4158
Contributing areas to public-supply wells at the Southbury Training School in Southbury, Connecticut, were mapped by simulating ground-water flow in stratified glacial deposits in the lower Transylvania Brook watershed. The simulation used nonlinear regression methods and informational statistics to estimate parameters of a ground-water flow model using drawdown data from...
Water-quality characteristics for selected streams in Lawrence County, South Dakota, 1988-92
Joyce E. Williamson, Timothy Scott Hayes
2000, Water-Resources Investigations Report 2000-4220
During the 1980?s, significant economic development and population growth began to occur in Lawrence County in the northern part of the Black Hills of western South Dakota. Rising gold prices and heap-leach extraction methods allowed the economic recovery of marginal gold ore deposits, resulting in development of several large-scale, open-pit...
Water quality of selected springs and public-supply wells, Pine Ridge Indian Reservation, South Dakota, 1992-97
Allen J. Heakin
2000, Water-Resources Investigations Report 99-4063
This report presents results of a water-quality study for the Pine Ridge Indian Reservation, South Dakota. The study was a cooperative effort between the U.S. Geological Survey and the Water Resources Department of the Oglala Sioux Tribe. Discharge and water-quality data were collected during 1992-97 for 14 contact springs located in...
Physical characteristics of dungeness crab and halibut habitats in Whidbey Passage, Alaska
Guy R. Cochrane, Paul R. Carlson, Michael E. Boyle, Gregory L. Gabel, Philip N. Hooge
2000, Open-File Report 2000-32
In Glacier Bay National Park, Alaska there are ongoing studies of Dungeness Crab (Cancer magister) and Pacific Halibut (Hippoglosus stenolepis). Scientists of the United States Geological Survey (USGS) are attempting to ascertain life history, distribution, and abundance, and to determine the effects of commercial fishing in the park (Carlson et...
Shoals and valley plugs in the Hatchie River watershed
Timothy H. Diehl
2000, Water-Resources Investigations Report 2000-4279
Agricultural land use and gully erosion have historically contributed more sediment to the streams of the Hatchie River watershed than those streams can carry. In 1970, the main sedimentation problem in the watershed occurred in the tributary flood plains. This problem motivated channelization projects (U.S. Department of Agriculture, 1970). By...
