Robin M. Bouse, Christopher C. Fuller, Samuel N. Luoma, Michelle I. Hornberger, Bruce E. Jaffe, Richard E. Smith
2010, San Francisco Estuary and Watershed Science (8) 1-28
The hydraulic gold-mining process used during the California Gold Rush and in many developing countries today contributes enormous amounts of sediment to rivers and streams. Commonly, accompanying this sediment are contaminants such as elemental mercury and cyanide used in the gold extraction process. We show that some of the mercurycontaminated...

Effect of historic land cover change on runoff curve number estimation in Iowa
Loren L. Wehmeyer, Frank H. Weirich
2010, Journal of Hydrologic Engineering (15) 692-695
Within three decades of European-descended settlers arriving in Iowa, much of the land cover across the state was transformed from prairie and forest to farmland, patches of forest, and urbanized areas. Between 1832 and 1859, the General Land Office surveyed the state of Iowa to aid in the disbursement of...

M. Hernandez, W. G. Kepner, D. G. Goodrich, Darius J. Semmens
2010, Book chapter
Human pressures on the natural resources of the United States have resulted in many unintended changes in our ecosystems, e.g., loss of biodiversity, habitat degradation, increases in the number of endangered species, and increases in contamination and water pollution. Environmental managers are concerned about broad-scale changes in land use and...

James A. Falcone, Daren M. Carlisle, David M. Wolock, Michael R. Meador
2010, Ecology (91) 621-621
Stream flow is a controlling element in the ecology of rivers and streams. Knowledge of the natural flow regime facilitates the assessment of whether specific hydrologic attributes have been altered by humans in a particular stream and the establishment of specific goals for stream-flow restoration. Because most streams are ungaged...

John D. Jastram, Carl E. Zipper, Lucian W. Zelanzny, Kenneth Hyer
2010, Journal of Environmental Quality (39) 1306-1316
Turbidity is an effective tool for estimating and monitoring suspended sediments in aquatic systems. Turbidity can be measured in situ remotely and at fine temporal scales as a surrogate for suspended sediment concentration (SSC), providing opportunity for a more complete record of SSC than is possible with physical sampling approaches....

Methods based on surface-water data
Richard W. Healy
2010, Book chapter, Estimating groundwater recharge
Streamflow data are commonly used to estimate recharge rates in humid and subhumid regions, in part because of the abundance of streamflow data and the availability of computer programs for analyzing those data. Most of the methods described in this chapter are easy to use, but application of any of...
