Ecohydrologic Connections in Semiarid Watershed Systems of Central Oregon USA

Creator:: Ochoa, Carlos G., Caruso, Phil, Ray, Grace, Deboodt, Tim, Jarvis, W. Todd, and Guldan, Steven J.
Abstract:: An improved understanding of ecohydrologic connections is critical for improving land management decisions in water-scarce regions of the western United States. For this study, conducted in a semiarid (358 mm) rangeland location in central Oregon, we evaluated precipitation-interception-soil moisture dynamics at the plot scale and characterized surface water and groundwater...

Discharge and suspended sediment a paired watershed study examining the effects of contemporary forest harvesting in the Oregon Coast Range

Creator:: Hatten, Jeff, Segura, Catalina, Bladon, Kevin, Hale, Cody, Ice, George, and Stednick, John
Abstract:: Forest harvesting practices can expose mineral soils, decrease infiltration capacities of soils, disturb the stream bank and channel, and increase erosion and fine sediment supply to stream channels. To reduce nonpoint source sediment pollution associated with forest management activities and to maintain the high water quality typically provided from forests,...

Long-term effects of forest harvesting on summer low flow deficiets in the Coast Range of Oregon

Creator:: Segura, Catalina, Bladon, Kevin, Hatten, Jeff, Jones, Julia A., Hale, Cody, Ice, George, and Souder, Jon
Abstract:: We examined long-term changes in daily streamflow associated with forestry practices with two datasets (this one and the original Alsea Streamflow dataset (1972) over a 60-year period (1959–2017) in the Alsea Watershed Study, Oregon Coast Range, Pacific Northwest, USA. In this contemporary period, 2006 to 2017 (12 water years), data...

Annual Costs of Wild Salmon Restoration Efforts in the Columbia River Basin

Creator:: Rice, Robert J.
Abstract:: The goal of this project was to estimate the total annual cost of salmon recovery efforts throughout the Columbia River Basin from all stakeholders, including direct and indirect costs. How much is spent on salmon recovery efforts each year in the Columbia River Basin? Depending on who you ask, you...

Exploring biophysical linkages between coastal forestry management practices and aquatic bivalve contaminant exposure

Creator:: Scully-Engelmeyer, Kaegan, Granek, Elise F., Nielsen-Pincus, Max, Lanier, Andy, Rumrill, Steven S., Moran, Patrick, Nilsen, Elena, Hladik, Michelle L., and Pillsbury, Lori
Abstract:: Terrestrial land use activities present cross-ecosystem threats to riverine and marine species and processes. Specifically, pesticide runoff can disrupt hormonal, reproductive, and developmental processes in aquatic organisms, yet non-point source pollution is difficult to trace and quantify. In Oregon, U.S.A., state and federal forestry pesticide regulations, designed to meet regulatory...

Geomorphic Evidence for Differential Rock Uplift Across the Southern Cascadia Forearc

Creator:: von Dassow, Wesley
Abstract:: The nature of upper plate deformation along the Cascadia subduction zone (CSZ) is poorly understood. Systematic covariation among topographic relief, geodetically determined uplift rates, decadal to millennial erosion rates, and the frequency of episodic tremor and slip (ETS) along the Cascadia forearc suggest a genetic association between forearc topography and...

River Restoration to Achieve a Stage 0 Condition: Summary of a Workshop Held November 5-6, 2020

Creator:: Behan, Jeff, Fetcho, K., Davis, R., and Gaines, L.
Abstract:: Restoration to achieve Stage 0 is a valley-scale, process-based (hydrologic, geologic and biological) approach that aims to reestablish stream depositional environments to maximize longitudinal, lateral, and vertical connectivity at base flows and facilitate development of dynamic, self-formed and self-sustaining wetland-stream complexes. The term Stage 0 originally described complex multi-channel conditions...

Vulnerability and adaptation of Pacific Northwest shellfisheries to ocean acidification

Creator:: Katz, Brian G.
Abstract:: The purpose of this study was to understand the vulnerability and adaptive capacity of shellfish stakeholders in the Pacific Northwest who are adapting to ocean acidification (OA). This study developed a geovisualization tool of existing environmental data for assessing species-specific risk profiles to OA (based on their exposure and sensitivity),...

Post-Conflict Forest Restoration in Western Syria, استعادة الغابات ما بعد الصراع في غرب سوريا

Creator:: Najim, Tara
Abstract:: This study examines the extent and causes of deforestation in western Syria over the past 11 years of war, and well as its social, environmental, and economic impacts. The coastal mountains of western Syria, which are home to nearly 80% of Syria's forests, have witnessed a 24% loss of forest...

An Investigation of Stage 0 Restoration in California and Oregon

Creator:: Schneider, Charles W.
Abstract:: Stream restoration efforts have increasingly started to focus on management actions that restore ecological function rather than focusing on species-specific habitat needs. Restoration practitioners in the Pacific Northwest have implemented numerous large-scale floodplain restoration projects to restore stream function at the valley scale. Some of these projects attempt to restore...
