Stephen D. Sebestyen, Elizabeth W. Boyer, James B. Shanley
2009, Journal of Geophysical Research (114)
[1] In coming decades, higher annual temperatures, increased growing season length, and increased dormant season precipitation are expected across the northeastern United States in response to anthropogenic forcing of global climate. We synthesized long-term stream hydrochemical data from the Sleepers River Research Watershed in Vermont, United States, to explore the...

Thomas G. Huntington, Andrew D. Richardson, Kevin J. McGuire, Katharine Hayhoe
2009, Canadian Journal of Forest Research (39) 199-212
We review twentieth century and projected twenty-first century changes in climatic and hydrologic conditions in the northeastern United States and the implications of these changes for forest ecosystems. Climate warming and increases in precipitation and associated changes in snow and hydrologic regimes have been observed over the last century, with...
Channel water balance and exchange with subsurface flow along a mountain headwater stream in Montana, United States
R.A. Payn, M.N. Gooseff, B.L. McGlynn, K.E. Bencala, S.M. Wondzell
2009, Water Resources Research (45)
Channel water balances of contiguous reaches along streams represent a poorly understood scale of stream-subsurface interaction. We measured reach water balances along a headwater stream in Montana, United States, during summer base flow recessions. Reach water balances were estimated from series of tracer tests in 13 consecutive reaches delineated evenly...

2009, Aquatic Toxicology (95) 133-143
In arid regions of the southwestern United States, municipal wastewater treatment plants commonly discharge treated effluent directly into streams that would otherwise be dry most of the year. A better understanding is needed of how effluent-dependent waters (EDWs) differ from more natural aquatic ecosystems and the ecological effect of low...
Introduction to paleoenvironments of Bear Lake, Utah and Idaho, and its catchment
Joseph G. Rosenbaum, Darrell S. Kaufman
2009, Special Paper of the Geological Society of America (450) v-xiii
In 1996 a group led by the late Kerry Kelts (University of Minnesota) and Robert Thompson (U.S. Geological Survey) acquired three piston cores (BL96-1, -2, and -3) from Bear Lake. The coring arose from their recognition of Bear Lake as a potential repository of long records of paleoenvironmental change. They...

Katherine Walton-Day, Eileen Poeter
2009, Applied Geochemistry (24) 2266-2282
Turquoise Lake is a water-supply reservoir located north of the historic Sugarloaf Mining district near Leadville, Colorado, USA. Elevated water levels in the reservoir may increase flow of low-quality water from abandoned mine tunnels in the Sugarloaf District and degrade water quality downstream. The objective of this study was to...

Stephen P. Faulkner, Prajwol Bhattarai, Yvonne C. Allen, John A. Barras, Glenn C. Constant
2009, Wetlands (29) 809-817
Baldcypress-water tupelo (cypress-tupelo) swamps are critically important coastal forested wetlands found throughout the southeastern U.S. The long-term survival and sustainability of these swamp forests is unknown due to large-scale changes in hydrologic regimes that prevent natural regeneration following logging or mortality. We used NWI wetland maps and remotely sensed hydrologic...
Hydrology and simulation of ground-water flow in the Tooele Valley ground-water basin, Tooele County, Utah
Bernard J. Stolp, Lynette E. Brooks
2009, Scientific Investigations Report 2009-5154
Ground water is the sole source of drinking water within Tooele Valley. Transition from agriculture to residential land and water use necessitates additional understanding of water resources. The ground-water basin is conceptualized as a single interconnected hydrologic system consisting of the consolidated-rock mountains and adjoining unconsolidated basin-fill valleys. Within the...

User's Guide to the Weighted-Multiple-Linear Regression Program (WREG version 1.0)
Ken Eng, Yin-Yu Chen, Julie.E. Kiang
2009, Techniques and Methods 4-A8
Streamflow is not measured at every location in a stream network. Yet hydrologists, State and local agencies, and the general public still seek to know streamflow characteristics, such as mean annual flow or flood flows with different exceedance probabilities, at ungaged basins. The goals of this guide are to introduce...
