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....

An Efficient Three-Dimensional FNPF Numerical Wave Tank for Large-Scale Wave Basin Experiment Simulation

Creator:: Nimmala, Seshu B., Yim, Solomon C., and Grilli, Stephan T.
Abstract:: This paper presents a parallel implementation and validation of an accurate and efficient three-dimensional computational model (3D numerical wave tank), based on fully nonlinear potential flow (FNPF) theory, and its extension to incorporate the motion of a laboratory snake piston wavemaker, as well as an absorbing beach, to simulate experiments...

Rigid-Object Water-Entry Impact Dynamics: Finite- Element/Smoothed Particle Hydrodynamics Modeling and Experimental Validation

Creator:: Challa, Ravi, Yim, Solomon C., Idichandy, V. G., and Vendhan, C. P.
Abstract:: A numerical study on the dynamic response of a generic rigid water-landing object (WLO) during water impact is presented in this paper. The effect of this impact is often prominent in the design phase of the re-entry project to determine the maximum force for material strength determination to ensure structural...

Performance-Based Design Methodology for Using Emergent Vegetation to Mitigate Wave Overtopping

Creator:: Ostrow, Kayla
Abstract:: To facilitate the design of Natural and Nature-Based Features (NNBF) for flood protection, this thesis expands an existing engineering design methodology to NNBF systems. The existing approach is a Level III reliability method for the performance-based design of traditional coastal engineering systems. The expanded methodology incorporates uncertainties inherent to both...

Conceptual Design of Advanced Construction Progress Monitoring with Terrestrial and Robotic Laser Scanning Systems

Creator:: Arjmand, Mohsen, Jung, Jaehoon, Olsen, Michael J., Lassiter, H. Andrew, and Jafari, Melika
Abstract:: Advanced geomatics tools such as robotic and terrestrial laser scanners have the potential to significantly improve the progress monitoring of construction sites throughout their life cycle, particularly in the concrete structures, from the initial stage to cracking the ground for excavation and shoring to outdoor pouring of concrete at above...

Bottleneck detection in modular construction factories using computer vision

Creator:: Panahi, Roshan, Louis, Joseph, Podder, Ankur, Swanson, Colby, and Pless, Shanti
Abstract:: The construction industry is increasingly adopting off-site and modular construction methods due to the advantages offered in terms of safety, quality, and productivity for construction projects. Despite the advantages promised by this method of construction, modular construction factories still rely on manually-intensive work, which can lead to highly variable cycle...

UAS-SfM Lab Exercise

Creator:: Simpson, Chase and Murphy, Robin
Abstract:: The objective of this lab is to gain experience collecting imagery with an unmanned aircraft system (UAS) and processing it in structure from motion (SfM) photogrammetry software to obtain georeferenced data products, including an orthomosaic in GeoTiff format and a point cloud in ASPRS’s LAS format.

Chloride Binding of Portland Limestone Cement containing Supplementary Cementitious Materials

Creator:: Then, Nathalene WY
Abstract:: Chloride binding in Portland limestone cements (PLC) can be attributed to the chemical reaction between chloride ions and carboaluminate phases to form Friedel’s salt and the physical interaction between chloride ions and calcium-silicate-hydrates (C-S-H). This thesis examines the chloride binding of mortar samples containing varying amounts of limestone, fly ash,...

The Number of Lanes and Crash Injury Severities of Commercial Motor Vehicle Drivers: Advanced Econometric Models and Applications

Creator:: Kim, Jaekook
Abstract:: Considering the deadly impacts of commercial motor vehicle (CMV) crashes on road safety, many previous studies have put in efforts to find the determinants of CMV crash injury severities. However, studies examining the impact of the different number of lanes on CMV crash injury severities are lacking. Besides, the importance...
