Creator:: Steele, Madeline, Bonak, Zoe, and Chang, Heejun
Abstract:: While the negative effects of urban development on freshwater systems are well documented, impacts of human disturbance on water quality vary depending on land cover, local climate, and temporal and spatial scales of analysis. To better understand this variation, we analyzed water quality data for a total of 15 sites...

Creator:: Waibel, M. Scott, Gannett, Marshall W., Chang, Heejun, and Hulbe, Christina L.
Abstract:: Effects of climate change in the Cascade Range will likely include more rain, less snow, and earlier snowmelt in the Cascade Range as compared to present conditions. These changes, in turn, will affect the timing of runoff, groundwater recharge, and groundwater discharge to spring-fed streams. This hydrologic response needs to...

Creator:: Mayer, Tim
Abstract:: Climate change will continue to profoundly affect water supply and aquatic ecosystems in the Pacific Northwest. Changes such as warmer air temperatures, increases in the proportion of winter rain versus snow, reduced spring snowpack, and earlier snowmelt all affect streamflow. The response to these climate impacts includes earlier runoff peaks,...

Creator:: Pangle, Luke, Gregg, Jillian, and McDonnell, Jeffrey
Abstract:: There is reasonable expectation that climate warming will accelerate the hydrologic cycle, resulting in greater evapotranspiration (ET) and reduced groundwater recharge (R) (or stream flow). Though qualitatively intuitive, quantifying these potential shifts in water budget partitioning is a contemporary challenge in hydrology, because the linkage between ET and R is...

Creator:: Gonzalez-Pinzon, Ricardo, Haggerty, Roy, Argerich, Alba, Acker, Sarah, and Myrold, David
Abstract:: After three decades of active research in hydrology and stream ecology, the connection between solute transport, stream metabolism and nutrient dynamics is still unresolved. This existing gap obscures the functionality of stream ecosystems and how they interact with other landscape processes. To date, determining rates of metabolism is accomplished with...

Creator:: Risley, John, Hay, Lauren E., and Markstrom, Steven L.
Abstract:: In 2008 the U.S. Geological Survey began a Global Change study that evaluated the watershed scale response to climate change in selected basins across the United States. Fourteen basins for which the Precipitation Runoff Modeling System (PRMS) had been calibrated and evaluated were selected as study sites. PRMS is a...

Creator:: La Marche, Jonathan L., Gates, Edward B., and Lite Jr., Kenneth E.
Abstract:: Over the last decade hydrologic monitoring efforts in the Upper Klamath Basin (UKB) of Oregon have increased in response to the continued strain on surface water and groundwater to meet competing biological and agricultural demands. The Oregon Water Resources Department (OWRD) increased its stream gaging network from three to ten...

Creator:: Curtis, David C. and Prakash, Om
Abstract:: Climate changes. That’s what climate does. It is a natural and dynamic process. The National Weather Service (NWS) recognizes on-going climate change by publishing new figures for average climate every ten years. Climate averages for precipitation, temperature, and other weather parameters are computed on a 30 year basis but only...

Creator:: Shimota, Richard J. and Hadley, Hans R.
Abstract:: Peak discharge estimates are fundamental in the design of hydraulic structures, embankment protection, and stream restoration efforts, as well as flood risk analysis. Historic stream gage records are commonly used in the development of peak discharge estimates for a particular watershed. Use of an entire stream gage record assumes hydrologic...
