Potential errors associated with stage-discharge relations for selected streamflow-gaging stations, Maricopa County, Arizona
Anne C. Tillery, Jeff V. Phillips, Joseph P. Capesius
2001, Water-Resources Investigations Report 2000-4224
Potential errors were derived for individual discharge measurements and stage-discharge relations for 17 streamflow-gaging stations in Maricopa County. Information presented primarily consists of stage and discharge data that were used to develop the stage-discharge relations that were in effect for water year 1998. Accuracy of the discharge measurements directly relate...

2001, Professional Paper 1647
Ground-water quality with respect to nitrate, major inorganic constituents, pesticides, stable isotopes, and tritium was assessed in the agricultural Tangshan region in the Hai He River basin of the People's Republic of China and compared with three similar regions in the United States: the Delmarva Peninsula of the States of...
Lead recycling in the United States in 1998
Gerald R. Smith
2001, Open-File Report 2001-170
This materials flow study includes a description of lead supply and demand factors for the United States to illustrate the extent of lead recycling and to identify recycling trends. Understanding the system of materials flow from source to ultimate disposition can assist in improving the management of the use of natural resources...

Computer program for simulation of variable recharge with the U. S. Geological Survey modular finite-difference ground-water flow model (MODFLOW)

2001, Open-File Report 2000-173
The Variable-Recharge Package is a computerized method designed for use with the U.S. Geological Survey three-dimensional finitedifference ground-water flow model (MODFLOW-88) to simulate areal recharge to an aquifer. It is suitable for simulations of aquifers in which the relation between ground-water levels and land surface can affect the amount and distribution of recharge. The method is based on the...
Quality of water on the Prairie Band Potawatomi Reservation, northeastern Kansas, February 1999 through February 2001
T. J. Trombley
2001, Water-Resources Investigations Report 2001-4196
Water-quality samples were collected from 20 surface-water sites and 7 ground-water sites across the Prairie Band Potawatomi Reservation in northeastern Kansas as part of a water-quality study begun in 1996. Water quality is a very important consideration for the tribe. Three creeks draining the reservation, Soldier, Little Soldier, and South...
Geologic map and digital database of the San Rafael Mtn. 7.5-minute quadrangle, Santa Barbara County, California
John G. Vedder, Richard G. Stanley, S. E. Graham, Z. C. Valin
2001, Open-File Report 2001-290
Geologic mapping of the San Rafael Primitive Area (now the San Rafael Wilderness) by Gower and others (1966) and Vedder and others (1967) did not include all of the San Rafael Mtn. quadrangle, and the part that was mapped was done in reconnaissance fashion. To help resolve some of the...

Patterns and processes of wetland loss in coastal Louisiana are complex: A reply to Turner 2001. Estimating the indirect effects of hydrologic change on wetland loss: If the Earth is curved, then how would we know it?

2001, Estuaries (24) 647-651
The coastal wetlands of Louisiana comprise a vast expanse of marine to freshwater wetland plant communities interspersed w-ith shallow bays and bayous. These wetlands were built by processes associated with the present-day Mississippi and Atchatfalaya River deltas and older distributaries occupied by the river over the past 7,000 }rears. The high rates of wetland...
Using high-resolution aeromagnetic surveys to map subsurface hydrogeology in sediment-filled basins: A case study over the Rio Grande Rift, Central New Mexico, USA
V. J. S. Grauch
2001, Exploration Geophysics (32) 209-213
High-resolution aeromagnetic surveys were acquired for the Albuquerque basin in the central Rio Grande rift, a basin filled with poorly consolidated sediments. The surveys proved successful in efficiently and economically mapping previously unknown hydrogeologic features of the shallow subsurface. This success suggests that aeromagnetic methods may be useful in hydrogeologic...

Very different crustal response to extreme extension in the southern Basin and Range and Colorado Plateau transition
Tom Parsons, Jill McCarthy, George A. Thompson
2001, Book chapter, The geologic transition, high plateaus to Great Basin - A symposium and field guide (the Mackin volume)
Clustered about the southwest edge of the Colorado Plateau lie many highly extended terranes. Among these are metamorphic core complexes, distinguished by low-angle normal faults with sufficient offset to expose middle crustal rocks at higher elevation relative to the surrounding areas. About 150 km to the southwest, strong extension in...

Canopy disturbance patterns in a bottomland hardwood forest in northeast Arkansas, USA
Sammy L. King, T. J. Antrobus
2001, Wetlands (21) 543-553
We characterized canopy disturbance patterns in a bottomland hardwood forest and identified linkages to tree species characteristics and interannual flooding patterns. We located 116 newly formed canopy gaps created by 136 gapmakers of 13 species. Over 83% of the gapmakers were snapped or uprooted (i.e., windthrow). The probability of any...
