A socio-technical study on the improved characterization of stakeholder behaviors and stream temperature in design of watershed conservation practices for climate change adaptation

Creator:: Noa-Yarasca, Efrain
Abstract:: Characterizing stakeholder behavior when making decisions in watershed management is a great challenge for planners, not only because plans are associated with physical uncertainties but also because stakeholders’ behaviors are influenced by numerous factors. Since stakeholders’ decision-making is linked to multiple types of uncertainty, communication of uncertainty to stakeholders by...

Numerical Modeling of Lateral Erosion during Reservoir Drawdown

Creator:: Artruc, Tessa C.
Abstract:: Reservoir drawdown is a management technique increasingly used in maintenance of aging infrastructure, decommissioning dams, and to promote the flushing of fish and sediment to downstream reaches. Erosional processes in the reservoir may result in excessive delivery of sediment to downstream habitats and infrastructure, a critical long-term consideration. Typically, numerical...

Natural Organic Matter Surface Coverage as a Predictor of Heteroaggregation between Nanoparticles and Colloids

Creator:: Oney, Dylan M.
Abstract:: Heteroaggregation of nanoparticles with naturally occurring colloids has been shown to be an important process in nanoparticle fate and transport in the aquatic environment. The advent of a functional assay to measure heteroaggregation attachment efficiencies has opened the door for further mechanistic studies. It is well known that natural organic...

Assessing the Link Between Large Wood Restoration and Groundwater Recharge and Storage: An Investigation of Indian Creek in Washington State

Creator:: Boylan, Nora C.
Abstract:: With decreasing snowpacks and changing precipitation patterns, Washington State seeks ways to conserve, protect, and enhance its water supply. Stream restoration has been viewed as a means to utilize alluvial aquifers for groundwater storage and augment late-season streamflow. However, the relationship between stream restoration and groundwater dynamics is still under...

Characterization of Stormwater Runoff from a County Maintenance Facility and Evaluation of Temporal Performance of Bioswale in Its Treatment

Creator:: Gyawali, Kshitiz
Abstract:: In the last few decades, a lot of studies have been conducted to study about the quality of stormwater runoff from various sites and conditions. Highways, residential areas, and commercial sites are the focus of most of these studies while limited studies have done examination of stormwater from Maintenance and...

Cometabolism of 1,4-Dioxane and Chlorinated Aliphatic Hydrocarbons by Pure Cultures of Rhodococcus rhodochrous 21198 and Mycobacterium ELW1 and in Groundwater Microcosms Fed Isobutane and Isobutene as Growth Substrates

Creator:: Krippaehne, Krysta J.
Abstract:: 1,4-dioxane and chlorinated aliphatic hydrocarbons (CAHs) such as trichloroethylene (TCE) and 1,1-dichloroethene (1,1-DCE) are hazardous compounds commonly found in soil and groundwater. Bioremediation through aerobic cometabolism is a potential option for the remediation of these contaminated sites. The purpose of this study was to examine the use of different primary...

An Exploration of Faculty Sensemaking in the Adoption of Course Social and Cognitive Engagement (CSCE) Surveys

Creator:: Ironside, Allyson J.
Abstract:: The work of engineering education researchers has resulted in the development of research-based instructional strategies (RBISs) aimed at providing educators with means to increase student learning. Research has shown that there is a disconnect between the development of RBISs and their use by educators. Means to make new practices more...

A GIS study of Benton County, Oregon, groundwater : Spatial distributions of selected hydrogeologic parameters

Creator:: Miles, Evan S.
Abstract:: Benton County has experienced substantial growth in the past 30 years, and is expected to continue growing (BCWP 2008). Continued development has occurred in the Willamette Valley, housing development in the nearby hills of the Coast Range is growing. New houses in the foothills of the Coast Range may not...

Physical Modeling of the Feedbacks Between a Reed Canarygrass (Phalaris arundinacea) Patch, Hydraulics, and Bedform Evolution

Creator:: Elliott, Susan H.
Abstract:: Reed Canarygrass (RCG) is an aggressive invader in aquatic ecosystems that swiftly modifies the environment and decreases biodiversity. A physical model was used to investigate the mechanisms by which RCG spreads. Experimental trials were implemented to examine feedbacks between a mid-channel patch of the flexible RCG, hydraulics, and bedform evolution...

Batch and Continuous Flow Column Studies of Methane Consumption and Methanol Production by Methylosinus Trichosporium OB3b and Methylomicrobium Buryatense 5GB1 Immobilized In Ca-Alginate and Agarose Hydrogels

Creator:: Molzahn, Paige
Abstract:: Two methanotrophs, M. trichosporium OB3b and M. buryatense 5GB1, were encapsulated using two methods to investigate the potential of methane conversion for biofuel production. Ca-alginate and low melt agarose were used to immobilize the methanotrophs for batch and continuous flow column testing. Varying protein concentrations, residence times, and immobilization methods...
