Diffusion of selected radionuclides through Hanford Trench 8 soil material

Creator:: Schwab, Kristen E.
Abstract:: Shallow land burial in vadose zone sediment at the Hanford Site in Washington is being considered for the disposal of Category 3 low-level waste. A series of column experiments were conducted to evaluate and model the performance of the soil surrounding the trench encasement material for iodine-129 and technetium-99 by...

Interactive Genetic Algorithms for watershed planning : an investigation of usability and human-centered design

Creator:: Piemonti, Adriana Debora
Abstract:: Degradation of watersheds is a major concern in areas where adverse climate effects and unsustainable use of the natural resources have caused extensive stresses to watershed systems (e.g., increased floods, increased droughts, worsened in-stream water quality) through the years. While considerable efforts are being made to generate technical solutions that...

Assessing the Impact of Three Intersection Treatments on Bicyclist Safety

Creator:: Scott-Deeter, Logan K..
Abstract:: Bicyclist safety at urban intersections is a critical element for encouraging an increase in bicycle commuting. With bicycle injury and fatality rates rising due to collisions with vehicles at signalized intersections, increasing the safety of riders continues to be an important consideration when promoting this mode of transportation. Previous research...

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...

The Application of Machine Learning Techniques on Marine Science Models

Creator:: Ellenson, Ashley
Abstract:: A variety of stakeholders require information about marine systems. In the open ocean, pilots of marine vessels require knowledge about environmental conditions for safe passage and route planning. On the coastline, communities rely on information about nearshore dynamics to increase safety from coastal hazards such as nearshore pollutants, coastal erosion,...

Transportation Infrastructure to Support Bicycling in Dense Urban Environments : Design and Operational Considerations for Bicycle Lanes in Proximity to Commercial Vehicle Loading Zones

Creator:: Ghodrat Abadi, Masoud
Abstract:: While sophisticated plans have been adopted nationally and globally to increase bicycling’s share of daily commutes, safety concerns have negatively impacted targeted bicycling growth. Specifically, truck traffic plays a pivotal role in bicyclists’ perceptions of safety and comfort, because of the severe consequences of bicycle-truck collisions. Several types of engineering...

Modeling shallow-water hydrodynamics : rotations, rips, and rivers

Creator:: Long, Joseph W.
Abstract:: Hydrodynamic models are used as a diagnostic tool to understand the temporal variability of shallow-water processes that are difficult to completely resolve with traditional field measurements. For all simulations, modeled quantities are qualitatively or quantitatively compared with available measurements to gain confidence in conclusions derived from the modeled results. In...

Assessing Seismic Rockfall Impacts on Mobility in Transportation Corridors

Creator:: Holtan, Katherine
Abstract:: The climate and geologic conditions of the Pacific Northwest leaves its roads highly susceptible to rockfall hazards. Rockfalls often occur on steep slopes that experience heavy rainfall, groundwater seepage, or strong shaking from earthquakes. The unpredictable nature of these events often creates substantial problems for communities, transportation infrastructure, and the...

Streambed scour and redeposition behavior in streambed simulated culverts over an annual period

Creator:: Stewart, Anna
Abstract:: The objective of this study was to provide first order observations of bed level changes occurring in streambed simulated culverts throughout an annual period. To accomplish this, 30 culvert sites were selected in Oregon and Washington, and monitored over, at least, a 2 year period. Streambed scour and redeposition data...

Observations and prediction of intermittent sediment suspension in the surf zone

Creator:: Yoon, Hyun Doug
Abstract:: In this dissertation the interactions between hydrodynamics, sediment suspension and transport, and morphological evolution in the surf zone was investigated with a large-scale laboratory experiment data, CROss-Shore Sediment Transport Experiment (CROSSTEX). The data set included comprehensive measurements of water surface elevation, fluid velocity, sediment concentration, and morphology for irregular waves...
