Waves on unsteady currents

Creator:: Haller, Merrick C. and Özkan-Haller, H. Tuba
Abstract:: Models for surface gravity wave propagation in the presence of currents often assume the current field to be quasi-stationary, which implies that the absolute wave frequency is time invariant. However, in the presence of unsteady currents or time-varying water depth, linear wave theory predicts a time variation of the absolute...

The effects of changing climate on estuarine water levels: a United States Pacific Northwest case study

Creator:: Parker, Kai, Hill, David, García-Medina, Gabriel, and Beamer, Jordan
Abstract:: Climate change impacts on extreme water levels (WLs) at two United States Pacific Northwest estuaries are investigated using a multicomponent process-based modeling framework. The integrated impact of climate change on estuarine forcing is considered using a series of sub-models that track changes to oceanic, atmospheric, and hydrologic controls on hydrodynamics....

Remote sensing of wave roller lengths in the laboratory

Creator:: Haller, Merrick C. and Catalán, P. A.
Abstract:: The optical intensity signals from surf zone waves in a laboratory flume are analyzed using several different phase‐averaging techniques, and a methodology is developed for estimating wave roller lengths and local wave dissipation. The intensity signals (i.e., phase‐averaged intensity profiles) of individual breaking waves are compared with the wave profiles...

Understanding Instructors Curriculum Planning Process for the Refinement and Dissemination of a Digital Platform to Share Transportation Education Materials

Creator:: Peters, Allie
Abstract:: Background The National Science Foundation (NSF) has funded multiple research projects dedicated to the development of research and evidence based instructional strategies in an effort to improve the state of science, technology, engineering and math (STEM) education in the US. These efforts have led to an abundance of research based...

Estimating Drag and Roughness along a Near-Vertical Ice-Ocean Boundary on a Grounded Iceberg

Creator:: Cohen, Nadia
Abstract:: Ice–ocean interactions have profound consequences for the ocean and climate, influencing the rate of sea level rise. Submarine melt is commonly parameterized using a three-equation formulation for the heat, salt, and momentum conservation equations coupled to a buoyant plume model, together called plume-melt theory. However, recent direct observations of terminus...

Wave Resource Assessments: Spacio-Temporal Effect of Wave Energy Converter Scale and Blue Economy Opportunities

Creator:: Dunkle, Gabrielle R.
Abstract:: Wave energy has the potential to power large and small factions of economies around the world alike. Current methods for determining the amount of wave energy resource available to wave energy converter (WEC) devices entail capturing the look of the sea state at large by presenting characteristic wave heights, periods,...
Resource Type:: Masters Thesis

Depth estimation and frontal imaging via X-band marine radar

Creator:: Honegger, David Andrew
Abstract:: This dissertation focuses on two core aspects of remote sensing: (a) interpretation of the remotely sensed data to identify and characterize sea surface features of interest, and (b) the quantitative analysis of previously characterized features to produce robust estimates of geophysical variables. Specifically, these aspects are addressed in the context...

Understanding the Similarities and Differences Between Academia and the Engineering Workplace through Barriers to Adoption, Epistemic Beliefs, and Problem-Solving Behavior

Creator:: Gestson, Sean Lyle
Abstract:: Engineering education research has led to a greater understanding of the gap in preparedness of students for the engineering industry. Multiple studies comparing the workplace and academic contexts and the participants in those contexts (i.e., students, faculty, and engineering practitioners) have emphasized similarities and differences between the two contexts by...

Climate Change Impacts to Estuarine Hydrodynamics: Tools, Methodologies, and Predictions

Creator:: Parker, Kai A.
Abstract:: Coastal communities in the U.S. Pacific Northwest (PNW) are rapidly engaging with the idea that hazards and environmental pressures are changing and may be characteristically different in the near future. This has led to a need for scientific knowledge and tools that can help coastal communities prepare and build resilience...

Probabilistic Tsunami Hazard and Damage Assessment of the Built Environment : Applied at Seaside, Oregon

Creator:: Park, Hyoungsu
Abstract:: Damage estimates to the built environment from tsunamis are important for disaster mitigation, including planning emergency response and recovery. This dissertation evaluates the damage states of buildings in a small urban coastal city, Seaside, Oregon, from tsunami hazards generated by a Cascadia Subduction Zone (CSZ) event. This study is separated...
