Summer Temperature Patterns in Headwater Streams of the Oregon Coast Range1
Journal of the American Water Resources Association - Tập 44 Số 4 - Trang 803-813 - 2008
Liz Dent, Danielle Vick, Kyle Abraham, Stephen H. Schoenholtz, Sherri L. Johnson
Abstract:  Cool summertime stream temperature is an important component of high quality aquatic habitat in Oregon coastal streams. Within the Oregon Coast Range, small headwater streams make up a majority of the stream network; yet, little information is available on temperature patterns and the longitudinal variability for these streams. In this paper we describe pr...... hiện toàn bộ
Nutrient Inputs to the Laurentian Great Lakes by Source and Watershed Estimated Using SPARROW Watershed Models1
Journal of the American Water Resources Association - Tập 47 Số 5 - Trang 1011-1033 - 2011
Dale M. Robertson, David A. Saad
Assessing BMP Effectiveness and Guiding BMP Planning Using Process‐Based Modeling
Journal of the American Water Resources Association - Tập 51 Số 2 - Trang 343-358 - 2015
Erin Brooks, Sheila M. Saia, Jan Boll, Lauren Wetzel, Zachary M. Easton, Tammo S. Steenhuis
AbstractThere is an increasing need for improved process‐based planning tools to assist watershed managers in the selection and placement of effective best management practices (BMPs). In this article, we present an approach, based on the Water Erosion Prediction Project model and a pesticide transport model, to identify dominant hydrologic flow paths and critical ...... hiện toàn bộ
BUILDING THE AGENDA FOR INSTITUTIONAL RESEARCH IN WATER RESOURCE MANAGEMENT1
Journal of the American Water Resources Association - Tập 40 Số 4 - Trang 925-936 - 2004
William Blomquist, Tanya Heikkila, Edella Schlager
ABSTRACT: This paper pursues more specifically the recommendations of a recent National Research Council report recommending greater attention to research on institutions in the field of water resource management. The important challenge for the future in institutional research lies in going beyond the observation that institutions are important and in explaining in...... hiện toàn bộ
The Role of Headwater Streams in Downstream Water Quality1
Journal of the American Water Resources Association - Tập 43 Số 1 - Trang 41-59 - 2007
Richard B. Alexander, Elizabeth W. Boyer, Richard A. Smith, Gregory E. Schwarz, Richard B. Moore
Abstract:  Knowledge of headwater influences on the water‐quality and flow conditions of downstream waters is essential to water‐resource management at all governmental levels; this includes recent court decisions on the jurisdiction of the Federal Clean Water Act (CWA) over upland areas that contribute to larger downstream water bodies. We review current watershed r...... hiện toàn bộ
AN EXAMINATION OF RELATIVE PERMEABILITY RELATIONS FOR TWO‐PHASE FLOW IN POROUS MEDIA1
Journal of the American Water Resources Association - Tập 23 Số 4 - Trang 617-628 - 1987
Avery H. Demond, Paul V. Roberts
ABSTRACT: A key parameter in modeling two‐phase flow phenomena is relative permeability. It is important to understand which variables influence relative permeability, especially since so few measurements of relative permeability have been made for typical contaminants at hazardous waste sites. This paper focuses on the effect of five variables on relative permeabil...... hiện toàn bộ
OXYGEN DEMAND IN ICE COVERED LAKES AS IT PERTAINS TO WINTER AERATION1
Journal of the American Water Resources Association - Tập 25 Số 6 - Trang 1169-1176 - 1989
Christopher R. Ellis, Heinz G. Stefan
ABSTRACT: Winterkill, the death of fish under ice due to oxygen deficiency, threatens hundreds of shallow lakes in the upper Midwest of the United States every winter. For decades, attempts have been made to prevent winterkill, usually through aeration, with mixed results. In large part, the failure of strategies to prevent winterkill can be linked to a lack of unde...... hiện toàn bộ
PLANNING FOR DROUGHT: MOVING FROM CRISIS TO RISK MANAGEMENT1
Journal of the American Water Resources Association - Tập 36 Số 4 - Trang 697-710 - 2000
Donald A. Wilhite, Michael J. Hayes, Cody Knutson, Kelly Helm Smith
ABSTRACT: Severe drought is a recurring problem for the United States, as illustrated by widespread economic, social, and environmental impacts. Recent drought episodes and the widespread drought conditions in 1996, 1998, and 1999 emphasized this vulnerability and the need for a more proactive, risk management approach to drought management that would place greater ...... hiện toàn bộ
Open Water Data in Space and Time
Journal of the American Water Resources Association - Tập 52 Số 4 - Trang 816-824 - 2016
David R. Maidment
AbstractAn Open Water Data Initiative has been established by the federal government to enhance water information sharing across the United States (U.S.) using standardized web services for geospatial and temporal data. In a parallel effort, the National Weather Service has established a new National Water Center on the Tuscaloosa campus of the University of Alabam...... hiện toàn bộ
EFFECTS OF MULTI‐SCALE ENVIRONMENTAL CHARACTERISTICS ON AGRICULTURAL STREAM BIOTA IN EASTERN WISCONSIN1
Journal of the American Water Resources Association - Tập 37 Số 6 - Trang 1489-1507 - 2001
Faith A. Fitzpatrick, Barbara C. Scudder, Bernard N. Lenz, Daniel J. Sullivan
ABSTRACT: The U.S. Geological Survey examined 25 agricultural streams in eastern Wisconsin the determine relations between fish, invertebrate, and algal metrics and multiple spatial scales of land cover, geologic setting, hydrologic, aquatic habitat, and water chemistry data. Spearman correlation and redundancy analyses were used to examine relations among biotic me...... hiện toàn bộ
