Creator:: Leon, Arturo S. and Gichamo, Tseganeh Z.
Abstract:: River flooding is a recurrent threat and its control and management continues to be a challenge. It has been recognized that effective flooding control requires a real-time strategy that combines optimization with a physically-based simulation model. Current real-time frameworks that combine simulation and optimization have two main drawbacks. The first...

Abstract:: In 2008 the Oregon Department of Environmental Quality (ODEQ) initiated a program to monitor Oregon’s surface waters and aquatic biota for the presence of pollutants that pose risks to human and/or environmental health. ODEQ’s Toxics Monitoring Program was first implemented in the Willamette River Basin (WRB) between 2008 and 2010....

Abstract:: As part of a larger study to examine the effect of climate change (CC) on estuarine resources, we simulated the effect of rising sea level, alterations in river discharge, and increasing atmospheric temperatures on water quality in the Yaquina Estuary. Due to uncertainty in the effects of climate change, initial...

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...

Abstract:: The City of Florence, local stakeholders, and partner agencies recently formed the Siuslaw Estuary Partnership (SEP) to address threats to drinking water quality and fish and wildlife habitat in the lower Siuslaw watershed. The Sole Source Dunal Aquifer within the lower Siuslaw watershed, which supplies the City ’s drinking water,...

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:: 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...

Abstract:: The McKenzie River serves as the sole source of drinking water for nearly 200,000 residents in Eugene, OR. The McKenzie River is also home to a number of threatened and endangered fish species. Whereas the majority of the upper watershed is forested, areas of rural development and agriculture occur along...

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...

Abstract:: The Columbia River Treaty has been in effect for over 45 years, but its future is uncertain. Starting in 2014, Canada and the United States will have the opportunity to announce ten years’ notice for termination of the current arrangement. As this artificial deadline approaches, stakeholders are working to determine...
