Ensemble-based data assimilation and depth inversion on the Kootenai River, ID, USA

Creator:: Landon, Kyle C.
Abstract:: Velocity measurements from drifter GPS records are assimilated and used in an ensemble-based inversion technique to extract the river bathymetry. The method is tested on a deep meandering reach and a shallow braided reach of the Kootenai River in Idaho, USA. The Regional Ocean Modeling System (ROMS) is used to...

Roughness and geometry effects of engineered log jams on 1-D flow characteristics

Creator:: Valverde, Rachelle S.
Abstract:: The re-introduction of large woody debris (LWD) into streams and rivers for stream restoration purposes is rapidly growing. Engineered log jams (ELJs) are man-made structures intended to mimic natural LWD structures, designed and installed to protect stream banks from erosion while increasing habitat diversity. Several studies have evaluated the flow...

Examining Wave Attenuation Rates and Subsurface Pore Pressures Across Three Marsh Restoration Sill Structures on a Sandy Bed

Creator:: Converse, Jordan D.
Abstract:: With rising sea levels and more frequent exposure to extreme storms, coastlines worldwide are vulnerable to increased erosion and loss of natural marsh lands. In an effort to lessen these impacts, there is a growing practice of adapting hard or “gray” coastline protection techniques to more nature-based features that promote...

Depth-dependence of surf zone eddies : a study at Duck, NC

Creator:: Aiken, Rebecca A.
Abstract:: Surf zone eddies (f < 0.01 Hz) are important in nearshore mixing, shoreline erosion, the distribution of pollutants, and ecological processes, such as offshore transport of larvae. Surf zone eddies have traditionally been treated as two-dimensional features with horizontal length scales larger than the local water depth. Studies by Lippmann...

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...

An Agent-Based Simulation for Emergency Warning Dissemination in a Multiplex Social Network

Creator:: Koll, Charles D.
Abstract:: The variety of natural disasters provide different sets of characteristics and properties with unique challenges. One significant difference between hazard types is prewarning lead time, the amount of time individuals have from a potential warning to the disaster occurring. Rapid onset disasters may not provide an official warning about a...

Tsunami propagation in large rivers : idealized cases and the Columbia River Estuary

Creator:: Kalmbacher, Kirk D.
Abstract:: The hazards associated with tsunamis are well known and have been studied for decades. The majority of research is, however, focused on open coastlines which bear the brunt of a tsunamis force. Other regions that can be strongly impacted by a tsunami are large estuaries. Here, the tsunami encounters a...

Reducing Centerline Rumble Strips Effects on Pavement Performance

Creator:: Weaver, Joshua D.
Abstract:: Centerline rumble strips (CLRS) have proven to be a cost-effective safety measure in reducing lane departure crashes. However, there are often unintended consequences associated with the installation of CLRS, particularly in rural mountainous areas or snow zones. These consequences include the accumulation of water and ice on the roadway and...

Effects of soil slope on the lateral capacity of piles in cohesionless soils

Creator:: Barker, Paul D.
Abstract:: Deep foundations, including driven piles, are used to support vertical loads of structures and applied lateral forces. Many pile supported structures, including bridges, are subjected to large lateral loads in the form of wind, wave, seismic, and traffic impact loads. In many practical situations, structures subjected to lateral loading are...
