Continuous Hydrologic Simulation of Johnson Creek Basin

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...

Climate Change: Natural Variability is a Big Deal Too!

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...

Quantitative Relationship between Resazurin and Respiration in Stream Ecosystems

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...

Emerging and Legacy Contaminants in POCIS, SPMDs, and the Largescale Sucker (Catostomus macrocheilus) in the Lower Columbia River – USGS ConHab Project

Creator:: Nilsen, Elena B., Alvarez, David, Madsen, James, Zaugg, Steven D., Perkins, Stephanie, Cranor, Walter, and Morace, Jennifer
Abstract:: An interdisciplinary study, USGS Columbia River Contaminants and Habitat Characterization (ConHab) project, is underway to investigate transport pathways, chemical fate and effects of polybrominated diphenyl ethers (PBDEs) and endocrine disrupting chemicals (EDCs) in aquatic media and the foodweb in the lower Columbia River. Polar organic chemical integrative samplers (POCIS) and...

Groundwater Storage and Flow in an Unconfined Pumice Aquifer, Antelope Unit, Chemult Ranger District, Winema-Fremont National Forest, Oregon

Creator:: Cummings, Michael
Abstract:: The study area lies north-northeast of Crater Lake National Park and is covered by 2 to 3 m of pumice deposited during the climactic eruption of Mount Mazama approximately 7700 years before present. The pumice deposit hosts unconfined, seasonally connected, perched aquifers that support groundwater dependent ecosystems at points of...

Spatial and Temporal Patterns in the Influence of Land Use on Water Quality in Five Portland Area Creeks Representing Differing Levels of Urbanization

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...

Assessment of Climate Change Impacts over the Willamette River Basin Using NARCCAP Dynamically Downscaled Datasets

Creator:: Halmstad, Andrew, Najafi, Mohammad Reza, and Moradkhani, Hamid
Abstract:: One important aspect related to the management of water resources under future climate variation is the occurrence of extreme precipitation events. In order to prepare for extreme events, namely floods and droughts, it is important to understand how future climate variability will influence the occurrence of such events. Recent advancements...

Hydrologic Response to Climate Change in the Sprague River Basin, Oregon

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...
