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...

Reconnaissance Investigation of Emerging Contaminants in Wastewater-Treatment-Plant Effluent and Stormwater Runoff in the Columbia River Basin

Creator:: Morace, Jennifer
Abstract:: In order to efficiently reduce toxic loading to the Columbia River basin, sources and pathways need to be identified. Little is known about the toxic loadings coming from wastewater-treatment facilities and stormwater runoff in the system. This study provides preliminary data on these sources and pathways throughout the basin. The...

A Hydroecology Investigation of Two Incised Riparian Wet Meadows Relating Change in Vegetation Communities with Headcut Incision and Soil Properties, Ochoco Mountains, OR

Creator:: Sheahan, Jamie
Abstract:: The inter-relationships of vegetation, soils, and stream channel erosion characteristics were examined in two riparian meadows of the Ochoco National Forest where progressive stream headcut incision is a critical resource management issue and restoration priority. Scientific literature establishes that headcut incision leads to lower groundwater tables, with corresponding shifts in...

Development of a Numerical Model for the Walla Walla Basin using IWFM (Groundwater-surface water modeling of the Walla Walla Basin Using IWFM)

Creator:: Scherberg, Jacob, Petrides-Jimenez, Aristides, Selker, John, Baker, Troy, and Henry, Rick
Abstract:: The Walla Walla basin lies in an arid region on the border of Eastern Washington and Oregon. A large portion of the area is devoted to agricultural production, relying on irrigation water diverted from the Walla Walla River and underlying aquifers occurring within Quaternary gravel and Mio-pliocene basalt formations. Heavy...

Building a Database on Best Management Practices for Pesticide Applications to Aquatic Environments and NOAA Trust Species

Creator:: Gianou, Kelsey, Emanuel, Robert, and Chan, Samuel
Abstract:: Pesticides are widely used to control undesirable pests and may be applied directly to water or lands directly adjacent to water. Pesticides are an option for habitat restoration but there can be unintended consequences to native, threatened and endangered species. There is very little information on the impacts of pesticides...

Using Partnership and Prioritization to Achieve Whole Watershed Restoration in the Pacific Northwest

Creator:: Senkyr, Lauren and Grant, Megan Callahan
Abstract:: The goal of the Whole Watershed Restoration Initiative (WWRI) is to restore natural functions of whole watersheds in Oregon, Washington, and Idaho, while amplifying community-based partnerships focused on the strategic restoration of Pacific salmon and steelhead ecosystems. The WWRI partners (Ecotrust, NOAA Restoration Center, the U.S. Forest Service's Pacific Northwest...

Water Conflict Management and Transformation in the Pacific Northwest and the World: The transformative moment & collaborative water use agreements

Creator:: Wolf, Aaron and Marshall, Dena
Abstract:: With the advance of climate change and growth of human populations and economies, the amount of freshwater in the world remains roughly the same as it has been throughout history. The amount economically available for human use is only 0.007% of the total, or about 13,500 km3, which is about...

Processing of Sediment Pulses Following the Removal of Three Small, Gravel-Filled Barriers

Creator:: Tullos, Desiree, Cox, Matt, Walter, Cara, Kibler, Kelly, and Woloveke, Greg
Abstract:: The decommissioning of dams, as an approach to restoring longitudinal connectivity and to managing aging infrastructure, presents valuable opportunities for organized study of channel responses to sediment pulses. Experiments with physical and numerical models suggest that rivers process coarse sediment pulses primarily through dispersion. In contrast, translation appears to be...

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...

Incorporating Climate Signals for Improved Ensemble Streamflow Prediction

Creator:: Najafi, Mohammad Reza and Moradkhani, Hamid
Abstract:: Ensemble Streamflow Prediction (ESP) provides the means for statistical post-processing of the forecasts and estimating the inherent uncertainties. On the other hand large scale climate variables provide valuable information for hydrologic predictions. In this study we propose a post-processing procedure that assigns weights to streamflow ensemble members using these large...
