Chromium (VI) sorption in soils : chemical behavior and solute transport modeling

Creator:: Schroth, Martin Herbert
Abstract:: Chromium spills on soils are causing severe groundwater contamination problems. To increase the performance of cleanup methods, the chemical behavior of chromium in soils and its transport through soils have to be understood. The objectives of this research were to investigate the sorption characteristics of chromium(VI) in soil and to...

Evaluation of remediation techniques for circular holes in the webs of wood I-joists

Creator:: Polocoser, Tiberiu
Abstract:: The objective of this project was to evaluate methods to remediate a wood I-joist with a single, circular hole in the web while leaving utilities in place. The methods were experimentally evaluated with a full-scale bending test using four equally spaced point loads. There were three depths of joists with...

Evaluation of the Performance of Lateral Spread Displacement Empirical Models for Subduction Zone Earthquake Case Histories

Creator:: Bunn, Michael
Abstract:: Lateral spread is a pervasive type of liquefaction-induced ground failure that occurs on gentle slopes or near free-faces, such as river channels. Resulting horizontal displacements can reach up to several meters, and can be considerably damaging to foundations, bridges, roadways, pipelines, etc. In the 1990s, Bartlett and Youd (1992a, 1995)...

Hybrid Survey Networks : Combining Real-time and Static GNSS Observations for Optimizing Height Modernization

Creator:: Weaver, Brian Jerald
Abstract:: To derive ellipsoid heights on passive marks with cm-level accuracy, many current specifications require the collection and adjustment of long-duration, static Global Navigation Satellite System (GNSS) sessions. To increase efficiency, a survey procedure that includes real-time kinematic vectors from a real-time GNSS network (RTN) was evaluated. Thirty different “hybrid” networks...

Dynamic behavior of silty soils

Creator:: Sunitsakul, Jutha
Abstract:: The cyclic resistance of predominantly fine-grained soils has received considerable attention following ground and foundation failures at sites underlain by silt-rich soils during recent earthquakes. In several cases substantial ground deformation and reduced bearing capacity of silt soils has been attributed to excess pore pressure generation during cyclic loading. These...

Exploring the Relationship between Bicycle Level of Traffic Stress and Reported Bicycle Collisions

Creator:: Vogt, Rachel
Abstract:: Transportation agencies need efficient methods to determine how to improve bicycle facilities in order to improve connectivity and safety. Many studies have used standalone methods such as level of traffic stress (LTS) and bicycle level of service (BLOS) to better understand bicycle mode share and network connectivity for a region...

A preliminary assessment of post-fire dissolved organic carbon concentrations in the McKenzie River basin, Oregon

Creator:: Hyatt, Charles
Abstract:: In recent decades, the occurrence of large, high severity wildfires has increased substantially in many parts of the world, including the western United States. These fires have the potential to impact water quality, aquatic ecosystems, and downstream communities for many decades. As such, it is increasingly important to understand the...

Networked Multi-agent Modeling of Connected Vehicles in Mixed Traffic Environment: A Decentralized Consensus Approach

Creator:: Wahid, Merih
Abstract:: Transportation systems are facing safety and operational challenges with a cost of billions of dollars annually in lost production time and wasted fuel. Infrastructure expansion, previously held as a panacea to most transportation challenges has lost its appeal due to financial, land-use and environmental constraints. Interest is surging in intelligent...

Improving Fatigue Cracking and Moisture Resistance of Asphalt Mixtures

Creator:: Obaid, Ihsan A.
Abstract:: The resistance of asphalt concrete pavement to distresses such as fatigue cracking and permanent deformation is governed by how well the structure can resist loading under a variety of traffic and climate-related conditions. Asphalt binder type and content are typically the variables that pavement engineers can manipulate to render the...

Crowdsourcing Data-driven Development of Bicycle Safety Performance Functions (SPFs) : Microscopic and Macroscopic Scales

Creator:: Chen, Chen
Abstract:: While riding bicycles has been promoted for its health, economic, and environmental benefits, it also complements other modes to complete a safe, efficient, and reliable transportation system. However, the dramatic increase of bicycle usage in the U.S. is accompanied by a growth of bicycle crashes. The U.S. Department of Transportation,...
