Biophysical feedback mediates effects of invasive grasses on coastal dune shape

Creator:: Zarnetske, Phoebe L., Hacker, Sally D., Seabloom, Eric W., Ruggiero, Peter, Killian, Jason R., Maddux, Timothy B., and Cox, Daniel
Abstract:: Vegetation at the aquatic–terrestrial interface can alter landscape features through its growth and interactions with sediment and fluids. Even similar species may impart different effects due to variation in their interactions and feedbacks with the environment. Consequently, replacement of one engineering species by another can cause significant change in the...

Assessment of Multi-year Hydrologic Performance of Bioretention Facility using Real-Time Sensors

Creator:: Alyousef, Hashim A.
Abstract:: Bioretention facilities are emerging as a popular way to deal with stormwater runoff in urban environments and address its concerns. Real-time sensors installed in bioretention facilities aid in understanding the performance and feasibility of such facilities over time. A bioretention facility in Corvallis, Oregon was monitored for a study period...

Long Wave Amplification in a Coral-Reef Lagoon

Creator:: Bheeroo, Vivek Anand
Abstract:: A series of laboratory experiments were conducted to study the wave field in the inner lagoon excited by ‘long’ incident waves. Three cases were considered: Cases A, B and C presenting incident waves of wavelength with factors of 1, 2 and 2.5 times the width of the reef respectively. The...

Synergistic Effects of Alkali Silica Reaction (ASR) and Fly Ash on the Corrosion Characteristics of Reinforced Concrete Systems

Creator:: Mazarei, Vandad
Abstract:: Alkali silica reaction (ASR) and corrosion of reinforcement are two deterioration mechanisms in reinforced concrete (RC) structures. These deterioration mechanisms can significantly damage a RC structure and reduce its service life. Supplementary cementitious materials (SCMs) are commonly used to improve the durability of RC systems containing reactive aggregate that are...

Non-destructive determination of yield stress for in-situ gusset plates

Creator:: Pflaum, Therese Michelle
Abstract:: Failure of a gusset plate that caused the I-35W Bridge collapse in Minneapolis, MN resulted in mandated rating of connections by the Federal Highway Administration (FHWA). Rating connections requires material properties as an input. The material properties are generally reported on the available detailed drawings for bridges. However, some bridges...

Numerical Simulation, Laboratory and Field Experiments, Analysis and Design of Wave Energy Converter and Mooring System

Creator:: Lou, Junhui
Abstract:: This dissertation studies the coupled fluid-structure interaction (FSI) of a wave energy converter (WEC) and evaluates the design of a WEC mooring system. The research is conducted in support of conceptual development, field test and performance evaluation of WECs as part of the mission of the Northwest National Marine Renewable...

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...

Wind induced torsional fatigue behavior of truss bridge verticals

Creator:: Keller, Philipp
Abstract:: The Astoria-Megler Bridge is a 6.6 kilometer (4.1 mile) long bridge, connecting Oregon and Washington on US 101, with a continuous steel truss main span of 376 m (1232 ft). It is the second longest main span bridge of this type in the world. Due to vortex shedding, some of...

Agent-based Tsunami Evacuation Model : Life Safety and Network Resilience

Creator:: Mostafizi, Alireza
Abstract:: Natural disasters could result in unnecessary loss of life and disproportionate suffering to families and communities if evacuation plans are not in place or understood by the public. In the Pacific Northwest, a magnitude 9.0 earthquake and tsunami from the Cascadia Subduction Zone (CSZ) represents one of the most pressing...

Toward wave energy in Oregon : predicting wave conditions and extracted power

Creator:: Oskamp, Jeffrey A.
Abstract:: Knowledge of wave conditions in nearshore regions supports the development of ocean wave energy technology by providing wave climatology for device design considerations, and power output estimates. By modeling wave transformation over the continental shelf, wave conditions were predicted in nearshore regions where potential wave energy conversion sites are located....
