Urban growth in American cities : glimpses of U.S. urbanization
Roger Auch, Janis Taylor, William Acevedo
2004, Circular 1252
The Earth's surface is changing rapidly. Changes are local, regional, national, and even global in scope. Some changes have natural causes, such as earthquakes or drought. Other changes, such as urban expansion, agricultural intensification, resource extraction, and water resources development, are examples of human-induced change that have significant impact upon...

2004, Scientific Investigations Report 2004-5020
In 1988, the Pawcatuck Basin (302.4 square miles) in southern Rhode Island (245.3 square miles) and southeastern Connecticut (57.12 square miles) was defined as a sole-source aquifer for 14 towns in southern Rhode Island and 4 towns in southeastern Connecticut. To determine water use and availability, the six subbasins in...

Jesús Rodríguez-Martínez, Luis Santiago-Rivera, Senen Guzman-Rios, Fernando Gómez-Gómez, Mario L. Oliveras-Feliciano
2004, Water-Resources Investigations Report 2003-4317
The surface-water assessment portion of this study focused on analysis of low-flow characteristics in local streams and rivers, because the supply of safe drinking water was a critical issue during recent dry periods. Low-flow characteristics were evaluated at one continuous-record gaging station based on graphical curve-fitting techniques and log-Pearson Type...
Estimates of flow duration, mean flow, and peak-discharge frequency values for Kansas stream locations
Charles A. Perry, David M. Wolock, Joshua C. Artman
2004, Scientific Investigations Report 2004-5033
Streamflow statistics of flow duration and peak-discharge frequency were estimated for 4,771 individual locations on streams listed on the 1999 Kansas Surface Water Register. These statistics included the flow-duration values of 90, 75, 50, 25, and 10 percent, as well as the mean flow value. Peak-discharge frequency values were estimated...

Geologic insights and suggestions on mineral potential based on analyses of geophysical data for the southern Toquima Range, Nye County, Nevada
D. R. Shawe, R.P. Kucks, T.G. Hildenbrand
2004, Miscellaneous Field Studies Map 2327-D
Aeromagnetic and gravity data provide confirmation of major structural and lithologic units in the southern Toquima Range, Nevada. These units include Cretaceous granite plutons and Tertiary calderas. In addition, the geophysical maps pinpoint numerous faults and lesser intrusions, and they suggest locations of several inferred subsurface intrusions. They also corroborate...

2004, Photogrammetric Engineering and Remote Sensing (70) 829-840
Multi-Resolution Land Characterization 2001 (MRLC 2001) is a second-generation Federal consortium designed to create an updated pool of nation-wide Landsat 5 and 7 imagery and derive a second-generation National Land Cover Database (NLCD 2001). The objectives of this multi-layer, multi-source database are two fold: first, to provide consistent land cover...

Methods of analysis by the U.S. Geological Survey National Water Quality Laboratory-Determination of polycyclic aromatic hydrocarbon compounds in sediment by gas chromatography/mass spectrometry
Mary C. Olson, Jana L. Iverson, Edward T. Furlong, Michael P. Schroeder
2004, Water-Resources Investigations Report 2003-4318
A method for the determination of 28 polycyclic aromatic hydrocarbons (PAHs) and 25 alkylated PAH homolog groups in sediment samples is described. The compounds are extracted from sediment by solvent extraction, followed by partial isolation using high-performance gel permeation chromatography. The compounds are identified and uantitated using capillary-column...

Conjunctive-use optimization model and sustainable-yield estimation for the Sparta aquifer of southeastern Arkansas and north-central Louisiana
Paul W. McKee, Brian R. Clark, John B. Czarnecki
2004, Water-Resources Investigations Report 2003-4231
Conjunctive-use optimization modeling was done to assist water managers and planners by estimating the maximum amount of ground water that hypothetically could be withdrawn from wells within the Sparta aquifer indefinitely without violating hydraulic-head or stream-discharge constraints. The Sparta aquifer is largely a confined aquifer of regional importance that comprises...

Urbanization impacts on the structure and function of forested wetlands
Stephen Faulkner
2004, Urban Ecosystems (7) 89-106
The exponential increase in population has fueled a significant demographic shift: 60% of the Earth's population will live in urban areas by 2030. While this population growth is significant in its magnitude, the ecological footprint of natural resource consumption and use required to sustain urban populations is even greater. The...
