Throughout American history water resources have played integral roles in shaping patterns of human settlement and networks of biological and economic exchange. In turn, humans have altered hydrologic systems to meet their needs. A paucity of climate and water discharge data for the seventeenth and eighteenth centuries, however, has left...
Vegetation index methods for estimating evapotranspiration by remote sensing
Edward P. Glenn, Pamela L. Nagler, Alfredo R. Huete
2010, Surveys in Geophysics (31) 531-555
Evapotranspiration (ET) is the largest term after precipitation in terrestrial water budgets. Accurate estimates of ET are needed for numerous agricultural and natural resource management tasks and to project changes in hydrological cycles due to potential climate change. We explore recent methods that combine vegetation indices (VI) from satellites with...

John L. Sabo, Jacques C. Finlay, Theodore A. Kennedy, David M. Post
2010, Science (330) 965-967
Food chain length (FCL) is a fundamental component of food web structure. Studies in a variety of ecosystems suggest that FCL is determined by energy supply, environmental stability, and/or ecosystem size, but the nature of the relationship between environmental stability and FCL, and the mechanism linking ecosystem size to FCL,...

Kathleen R. Murphy, Kenna D. Butler, Robert G. M. Spencer, Colin A. Stedmon, Jennifer R. Boehme, George R. Aiken
2010, Environmental Science & Technology (44) 9405-9412
The fluorescent properties of dissolved organic matter (DOM) are often studied in order to infer DOM characteristics in aquatic environments, including source, quantity, composition, and behavior. While a potentially powerful technique, a single widely implemented standard method for correcting and presenting fluorescence measurements is lacking, leading to difficulties when comparing...

Andrew S. Gendaszek, Christopher S. Magirl, Christiana R. Czuba, Christopher P. Konrad, Rand Little
2010, Report
Flow regulation, bank armoring, and floodplain alteration since the early 20th century have contributed to significant changes in the hydrologic regime and geomorphic processes of the Cedar River in Washington State. The Cedar River originates in the Cascade Range, provides drinking water to the Seattle metropolitan area, and supports several...
Use of regression‐based models to map sensitivity of aquatic resources to atmospheric deposition in Yosemite National Park, USA
David W. Clow, Leora Nanus, Brian Huggett
2010, Water Resources Research (46)
An abundance of exposed bedrock, sparse soil and vegetation, and fast hydrologic flushing rates make aquatic ecosystems in Yosemite National Park susceptible to nutrient enrichment and episodic acidification due to atmospheric deposition of nitrogen (N) and sulfur (S). In this study, multiple linear regression (MLR) models were created to estimate...

Joseph S. Walder
2010, Journal of Glaciology (56) 1079-1086
The theory of channelized water flow through glaciers, most commonly associated with the names of Hans Röthlisberger and Ron Shreve and their 1972 papers in the Journal of Glaciology, was developed at a time when interest in glacier-bed processes was expanding, and the possible relationship between glacier sliding and water...

Christopher M.U Neale, Michael H. Cosh, editor(s)
2010, Conference Paper, Remote sensing and hydrology
Riparian evapotranspiration (ET) was measured on a salt cedar (Tamarix spp.) dominated river terrace on the Lower Colorado River from 2007 to 2009 using tissue-heat-balance sap flux sensors at six sites representing very dense, medium dense, and sparse stands of plants. Salt cedar ET varied markedly across sites, and sap...

2010, Estuaries and Coasts (34) 106-119
Florida manatees (Trichechus manatus latirostris) overwintering in the Ten Thousand Islands and western Everglades have no access to power plants or major artesian springs that provide warm-water refugia in other parts of Florida. Instead, hundreds of manatees aggregate at artificial canals, basins, and natural deep water sites that act as...
Stimulation of methane generation from nonproductive coal by addition of nutrients or a microbial consortium
Elizabeth Jones, Mary A. Voytek, M.D. Corum, William H. Orem
2010, Applied and Environmental Microbiology (76) 7013-7022
Biogenic formation of methane from coal is of great interest as an underexploited source of clean energy. The goal of some coal bed producers is to extend coal bed methane productivity and to utilize hydrocarbon wastes such as coal slurry to generate new methane. However, the process and factors controlling...
