Creator:: Brooks, J. Renee, Wigington, Parker J. Jr, Kendall, Carol, Coulombe, Rob, Comeleo, Randy, and Rodecap, Kent
Abstract:: Climate change is expected to dramatically alter the timing and quantity of water within the nation’s river systems. These changes are driven by variation in the form, location and amount of precipitation that will affect the temporal and spatial distribution of river source water over time. To manage the impact...

Creator:: Lite Jr., Kenneth E.
Abstract:: Columbia River Basalt Group (CRBG) aquifers are commonly thought to be relatively flat lying, laterally extensive, and mostly confined, and therefore not likely to be directly connected to surface water. However, many of the CRBG units in south-central Washington and north-central Oregon were deposited within evolving synclinal structures of the...

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:: Madadgar, Shahrbanou
Abstract:: Drought events are usually characterized by their duration, severity, and intensity which are calculated based on different indices for drought recognition. Streamflow Drought Index (SDI) used in hydrological droughts is applied in this study to calculate drought variables of historical events in Upper Klamath River basin in Oregon. Historical extreme...

Creator:: Reeve, Todd
Abstract:: Across Oregon and other PNW states thousands of miles of rivers, streams and adjacent wetlands are chronically de-watered as a result of over-appropriated water rights. In Montana alone, chronic or periodic de-watering occurs in over 4,000 miles of streams across 381 different river or stream systems. The ecological harm resulting...

Creator:: Grant, Gordon E., Tague, Christina, Safeeq, Mohammad, and Lewis, Sarah
Abstract:: Spatial patterns of summer streamflow in the Cascade Mountains of Oregon vary dramatically between the geologically distinct High and Western Cascade regions. A key control is the partitioning of water input between a fast-draining shallow subsurface flow network (Western Cascades) versus a slow-draining deeper groundwater system (High Cascades). These differences...

Creator:: Campana, Michael E.
Abstract:: The specter of climate change looms large over Oregon. Although hydroclimatologic models predict a warmer Oregon, the total volume of precipitation may not change significantly. However, the character (rain vs. snow) and spatial and temporal distributions of precipitation will likely change. The state is already witnessing earlier snowmelt in the...

Creator:: Chang, Heejun, Anthony, Terrance, Ennaanay, Driss, and Sharma, Manu
Abstract:: Water related ecosystem services (WES), such as flow regulation, drinking water supply, temperature regulation, and water recreational activities, are affected by anthropogenic climate change. Forecasting potential shifts in such WES is critical to identifying the form and magnitude of likely impacts. We quantified the levels and values of WES under...
