Remote Sensing Tools for Evaluating Climate Change Impacts in Coastal Environments

Creator:: Herrmann, Joan F.
Abstract:: Climate change has pervasive impacts on Earth’s diverse ecosystems. Observed and projected effects that impact coastal environments pose unique challenges. Coastal regions provide numerous ecosystem services (e.g., fisheries, nursery habitats, erosion control, and water filtering and detoxification), house 40% of the US population, and contribute to 58% of the national...

Reliability-based Serviceability Limit State Design Procedures for Shallow Foundations

Creator:: Huffman, Jonathan C.
Abstract:: Reliability-based geotechnical foundation design focusses on soil and structure analysis that meets necessary safety, performance and/or serviceability criteria, calibrated based on probabilistic analyses and an accepted level of risk. As the civil engineering community seeks to better harmonize geotechnical and structural design methodologies, reliability-based design is being incorporated more into...

Use of Controlled Blasting to Quantify the Dynamic, In-Situ, Nonlinear Inelastic Response of Soils

Creator:: Jana, Amalesh
Abstract:: The seismic response of deep deposits of liquefiable and cyclic-softening susceptible soils has presented the geotechnical profession with significant engineering challenges. Strong ground motions may serve to soften soils under cyclic shear, trigger liquefaction, and produce damaging displacements as a consequence. This study improves the understanding of the in-situ, nonlinear,...

An investigation into the role of spatial variability on liquefaction consequence severity

Creator:: Cary, John R.
Abstract:: During the Canterbury Earthquake Sequence (CES) in Christchurch, NZ, an estimated $15B in damages occurred due to liquefaction-induced phenomena, illustrating the importance of understanding site-specific responses to seismic ground motions, as well the importance of accurately predicting liquefaction severity. One potential method for improving the understanding of how a site...

Engineering Services of Submerged Aquatic Vegetation (SAV): Investigation of the Land-Building and Energy-Attenuating Properties of SAV Habitats Across Spatial Scales

Creator:: Holzenthal, Elizabeth R.
Abstract:: Submerged aquatic vegetation (SAV) species, such as seagrasses, are highly valued in estuaries because of the many economic, ecological, and cultural services that they provide, including shelter for fisheries, minimizing water turbidity, and improving am-bient water quality. SAV can also alter its physical environment by attenuating wave and current velocities,...

Morphodynamic Evolution of Coastal Oregon: Using New Lidar-derived Beach and Sand Dune Morphometrics to Explore Multi-decadal Change

Creator:: Light, Jacob W
Abstract:: The coast of Oregon is highly dynamic, with beach and dune morphodynamics constantly evolving in response to physical and ecological forcing at scales ranging from seconds to decades and meters to tens of kilometers. Evaluating spatial and temporal trends in shoreline evolution is paramount in understanding and eventually developing a...

Measuring and Correcting the Electrical Resistivity of Concrete Pore Solution in Fresh Mixtures

Creator:: Biever, Joseph H.
Abstract:: A vital aspect of concrete construction is quality assurance and control (QA/QC). Engineered structures must meet pre-determined and agreed-upon strength and durability requirements. Concrete falls into a specific category of infrastructure material because in most cases, these strength and durability requirements cannot be found until the material has at least...

Reactivity Testing of Waterglass and the Investigation into an Alternative Binder Enhanced with Cellulose Nanocrystals

Creator:: McAlexander, Melissa
Abstract:: Most of the concrete in the world is produced using hydraulic cement (ordinary portland cement, OPC) and siliceous or alumino-siliceous supplementary cementitious materials (SCM). Due to the shift in focus toward environmental sustainability within the construction industry, alkali-activated cementitious systems (AAC) have gained significant attention to reduce the carbon footprint...

Evaluation and Modification of a Thixotropic Fluid Model for Liquefaction Triggering with Application to Laboratory Tests and Lateral Spreading

Creator:: Brown, Tovey M.
Abstract:: Earthquake-induced liquefaction is a large contributor to damage observed following seismic events. Commonly observed damage consists of significant ground and structural failure due to the deformation of large volumes of soil due to soil liquefaction and lateral spreading. A significant focus of geotechnical seismic research concentrates on the development and...

Regional and Site-Specific Vulnerabilities of the Western Power Grid from a M9.3 Cascadia Subduction Zone Earthquake

Creator:: Lathrop Eve D.
Abstract:: The likelihood of a Cascadia Subduction Zone (CSZ) earthquake is estimated between 37 to 42% in the next 50 years, leading to strong shaking, liquefaction, landsliding, and other seismic ground failure resulting in major impacts to critical lifelines such as the western power grid. Electrical power is essential for continued...
