Tectonics of the Georgia Basin, northwest Washington State, USA, and southwest British Columbia, Canada
(2013-07-25)GPS strain and recent neotectonic studies in northwest Washington and southwest British Columbia indicate long term north-south shortening of the Cascadia forearc extends north of recognized active faults. This study reviews ... -
Testing of a New Composite Framing System for Vertical Evacuation Structures
Communities on the coast of the pacific northwest are vulnerable to earthquakes followed bytsunami. These communities have little to no access to high ground and therefore vertical evaluation structures are needed. Vertical ... -
Testing of a Reinforced Concrete Core Wall for Tsunami Vertical Evacuation Shelter Structures in a Wave Flume
Communities in the coastal northwest of the United States realize the threat of tsunamis. An important implementation to prevent loss of life during a tsunami is the construction of vertical evacuation shelters (VES). These ... -
The Applicability of Sliding Block Analyses for the Prediction of Lateral Spreading Displacements
Liquefaction-induced lateral spreading deformations can pose significant risks to bridge pile foundations, underground utilities, and shallow foundation systems, particularly at sites in seismically active areas near ... -
The dynamics of cross-shore sediment transport in the Rhine region of freshwater influence
River plumes are critical to the exchange of suspended particulate matter (SPM) between nearshore regions and shelf seas. These exchanges contribute fundamentally to the health and function of the coastal ecosystem, and ... -
The effect of different sludge pretreatment methods on mitigation of anaerobic digester foaming
In this study, waste activated sludge obtained from two full-scale treatment plants with foaming issues was pretreated with acid/alkali treatment, acid-phase fermentation, thermal treatment, sonication, and metal salt ... -
The Effects of Ice and Currents on Wave-breaking Turbulence at the Ocean Surface
Breaking waves are critical to the exchange of momentum, gasses, and heat between the atmosphere and ocean. In open water, these exchanges control the growth and decay of waves, and have implications for global heat and ... -
The effects of mixing on arsenic mobilization and transport in a shallow lake
Arsenic, a heavy metal, is a neurotoxin and carcinogen that has been released into the environment at accelerated rates due to human activities. Arsenic has accumulated in the sediments of many lakes around the world and ... -
The fate and dynamics of a river plume in the surf zone
Small river outflows that directly enter the surf zone,where waves break near the shore, are a common feature of the world's coastlines. Rivers transport sediment, nutrients, and pollutants from the terrestrial to the ... -
The role of market scale in electric vehicle adoption: consumer and infrastructure perspectives
This thesis seeks to improve understanding of the role of market scale in electric vehicle (EV) adoption, by exploring consumer and infrastructure perspectives. First, we use new vehicle post-purchase consumer satisfaction ... -
The role of sand in Wave-Supported Gravity Flows over primarily muddy seabeds
Wave-supported gravity flows (WSGF) are one of the most crucial processes contributing to sediment transport across continental shelves with gentle bottom slopes. This dissertation studies the mechanisms of WSGF over ... -
The role of waves in the autumn Arctic Ocean
Recent decline of sea ice coverage in the Arctic Ocean has resulted in a substantial seasonal wave climate. Waves generated in the open water are attenuated far into the sea ice, but are a defining feature of the marginal ... -
The Use of Automatic Identification System Data to Determine Appropriate Stand-On Vessel Maneuvers
The violation of the International Regulations for Preventing Collisions at Sea (COLREGS) is a precursor to the majority of collisions. These violations may indicate a poor safety culture within shipping or they may indicate ... -
The Value of Cloud Computing Technology in Public Transportation Construction
The analysis of large datasets to create value using cloud computing technology has helped many industries improve decision-making processes and better predict risk. The construction of transportation infrastructure systems ... -
Three-Dimensional Effects of Tsunami Impact on Bridges
Field investigations following major tsunamis in recent years have shown that damage to and loss of bridge structures can cause delays in disaster relief and recovery. The damaged bridges were subject to extreme fluid loads ... -
Three-Dimensional Nearshore Currents and Eddies on an Alongshore-Variable Barred Beach
Three-dimensional circulation in the nearshore region is critical for contaminants, sediment, and larvae dispersion along the coast and transport between the surf zone and the inner shelf. In the surf zone, eddies generated ... -
Tidal flat thermodynamics
(2013-11-14)Intertidal flats are important coastal margin environments linking the terrestrial and marine ecosystems. This dissertation studies the thermodynamic processes of tidal flats over tidal, fortnightly, and seasonal timescales ... -
Towards a multi-scale, socio-technical view of the design and evaluation of water, sanitation, and hygiene infrastructure
Water, sanitation, and hygiene (WASH) are important prerequisites to human health, yet global investments in this infrastructure do not always deliver the expected benefits. The relationships between WASH and health are ... -
Towards Forecast-Informed Sustainable Hydropower Operations
To reduce the dependence on fossil fuels, the world needs to mainstream the use of clean and renewable energy sources. Hydropower remains the key renewable source to provide baseload power due to its relatively stable ... -
Towards the Improvement of Drought Monitoring and Prediction in the United States
(2012-09-13)Drought and heat waves resulted in economic losses of $171 billion in the United States between 1980 and 2007, losses which emphasize the need for a proactive risk management approach for drought management. The motivation ...
