Flow and salt transport in the Suwannee River estuary, Florida, 1999–2000: Analysis of data and three-dimensional simulations
Jerad D. Bales, S. A. Tomlinson, Gina Tillis
2006, Professional Paper 1656-B
A three-dimensional numerical model was developed to assist in the evaluation of the effects of changes in freshwater flow on the salinity regime of the lower Suwannee River, its estuary, and Suwannee Sound. Hydrodynamic and salt-transport modeling were supported by data from a comprehensive data-collection network operated in the lower Suwannee...
MODOPTIM: A general optimization program for ground-water flow model calibration and ground-water management with MODFLOW
Keith J. Halford
2006, Scientific Investigations Report 2006-5009
MODOPTIM is a non-linear ground-water model calibration and management tool that simulates flow with MODFLOW-96 as a subroutine. A weighted sum-of-squares objective function defines optimal solutions for calibration and management problems. Water levels, discharges, water quality, subsidence, and pumping-lift costs are the five direct observation types that can be compared...

Use of the Multi-Node Well (MNW) package when simulating solute transport with the MODFLOW ground-water transport process
Leonard F. Konikow, G.Z. Hornberger
2006, Techniques and Methods 6-A15
This report describes modifications to a U.S. Geological Survey (USGS) three-dimensional solute-transport model (MODFLOW-GWT), which is incorporated into the USGS MODFLOW ground-water model as the Ground-Water Transport (GWT) Process. The modifications were made to create compatibility between the Multi-Node Well (MNW) Package for MODFLOW and the MODFLOW-GWT model. This compatibility...

2006, Water Data Report VA-05-2
Water-resources data for the 2005 water year for Virginia consist of records of water levels and water quality of ground-water wells. This report (Volume 2. Ground-Water-Level and Ground-Water-Quality Records) contains water levels at 349 observation wells and water quality at 29 wells. Locations of these wells are shown on figures...
Use of sediment rating curves and optical backscatter data to characterize sediment transport in the Upper Yuba River watershed, California, 2001-03
Jennifer A. Curtis, Lorraine E. Flint, Charles N. Alpers, Scott Wright, Noah P. Snyder
2006, Scientific Investigations Report 2005-5246
Sediment transport in the upper Yuba River watershed, California, was evaluated from October 2001 through September 2003. This report presents results of a three-year study by the U.S. Geological Survey, in cooperation with the California Ecosystem Restoration Program of the California Bay-Delta Authority and the California Resources Agency. Streamflow and...

Facing the great disaster : How the men and women of the U.S. Geological Survey responded to the 1906 "San Francisco Earthquake"
Elizabeth M. Colvard, James Rogers
2006, General Information Product 31
It was the most devastating earthquake in California’s history. At 5:12 a.m. on April 18, 1906, the ground under the San Francisco Bay Area shook violently for more than 40 seconds. The magnitude 7.8 earthquake created a rupture along nearly 300 miles of the San Andreas Fault and was felt...

2006, Scientific Investigations Map 2918
The rocks and fossils of the San Francisco Bay region reveal that the geology there is the product of millions of years at the active western margin of North America. The result of this history is a complex mosaic of geologic materials and structures that form the landscape. A geologic...
Ground-water, surface-water, and water-chemistry data, Black Mesa area, northeastern Arizona — 2004–05
Margot Truini, J. P. Macy
2006, Open-File Report 2006-1058
The N aquifer is the major source of water in the 5,400-square-mile area of Black Mesa in northeastern Arizona. Availability of water is an important issue in this area because of continued industrial and municipal use, a growing population, and precipitation of about 6 to 14 inches per year. The monitoring...
