U.S. Geological Survey Quality-Assurance Project for Sediment Analysis
John D. Gordon, Carla Newland
2000, Fact Sheet 031-00
Introduction Sediment is derived primarily from natural weathering of rock and is an assemblage of individual mineral grains that are then deposited by some physical agent, such as water, wind, ice, or gravity (Fetter, 1988). The U.S. Geological Survey (USGS) samples sediments and collects data on the amount of sediment in...

Phosphorus loads entering Long Pond, a small embayment of Lake Ontario near Rochester, New York
Donald A. Sherwood
1999, Fact Sheet 128-99
IntroductionLong Pond is one of many small, shallow embayments along the southern edge of Lake Ontario (fig. 1). These embayments are an important recreational resource and wildlife habitat; thus, maintaining their natural state is essential to their continued use. In recent decades, Long Pond and the adjacent Cranberry Pond have...
A global digital elevation model - GTOP030
1999, Fact Sheet 123-99
GTOP030, the U.S. Geological Survey's (USGS) digital elevation model (DEM) of the Earth, provides the flrst global coverage of moderate resolution elevation data. The original GTOP30 data set, which was developed over a 3-year period through a collaborative effort led by the USGS, was completed in 1996 at the USGS...

Water use in Kansas, 1990 and 1995
J. F. Kenny
1999, Fact Sheet 090-99
This fact sheet illustrates comparative water use from ground and surface sources for 1990 and 1995 for the largest categories of use in Kansas: public supply, irrigation, industrial and mining, livestock, and thermoelectric power generation. Total populations, including those served by public-water suppliers and those using private wells, also are...

Channel stability of the Neosho River downstream from John Redmond Dam, Kansas
Kyle E. Juracek
1999, Fact Sheet 088-99
The stability of the Neosho River channel downstream from John Redmond Dam, in southeast Kansas, was investigated using multi-date aerial photographs and stream-gage information. Bankfull channel width was used as the primary indicator variable to assess pre- and post-dam channel change. Five 6-mile river reaches and four stream gages were...
Digital Data Set of 14-Digit Hydrologic Units in Indiana
Krysten M. DeBroka, David A. Cohen, Robert E. Dunn, Bruce J. Nielsen
1999, Fact Sheet 143-99
A hydrologic unit is an area of land that can contribute surface-water runoff to a designated outlet point. As part of an initiative to create a nationally uniform hydrologic-unit data base, the U.S. Geological Survey and the Natural Resources Conservation Service, in cooperation with the Indiana Department of Environmental Management...
Improvements to the DRASTIC ground-water vulnerability mapping method
Michael G. Rupert
1999, Fact Sheet 066-99
Ground-water vulnerability maps are designed to show areas of greatest potential for ground-water contamination on the basis of hydrogeologic and anthropogenic (human) factors. The maps are developed by using computer mapping hardware and software called a geographic information system (GIS) to combine data layers such as land use, soils, and...

Martin R. Risch
1999, Fact Sheet 105-99
As part of the U.S. Department of Defense Base Realignment and Closure process, the former Fort Benjamin Harrison in Marion County, Indiana (called 'Fort Harrison' in this fact sheet), was placed on the Base Closure List in 1991. Property disposal and reuse activities began when Fort Harrison was decommissioned in...

Water-quality assessment of south-central Texas — Comparison of water quality in surface-water samples collected manually and by automated samplers
Patricia B. Ging
1999, Fact Sheet 172-99
Surface-water sampling protocols of the U.S. Geological Survey National Water-Quality Assessment (NAWQA) Program specify samples for most properties and constituents to be collected manually in equal-width increments across a stream channel and composited for analysis. Single-point sampling with an automated sampler (autosampler) during storms was proposed in the upper part...
Geologic framework and hydrogeologic properties of the Seco Creek Watershed, Texas
D.S. Brown, John G. Mosier, G.M. Nalley
1999, Fact Sheet 104-98
In 1991, the U.S. Geological Survey (USGS), in cooperation with the U.S. Department of Agriculture (USDA) and the Texas State Soil and Water Conservation Board, began a study to evaluate the effects of agricultural best-management practices on surface- and ground-water quantity and quality in the Seco Creek watershed. The USGS...
USGS Map-on-Demand Printing
Water Resources Division, U.S. Geological Survey
1999, Fact Sheet 074-99
Currently, the U.S. Geological Survey (USGS) uses conventional lithographic printing techniques to produce paper copies of most of its mapping products. This practice is not economical for those products that are in low demand. With the advent of newer technologies, high-speed, large-format printers have been coupled with innovative computer software...
