Estuarine sediment controls on trace metal distributions

Creator:: Davies-Colley, Robert J.
Abstract:: Sediments are the major compartment in aquatic environments for many materials of toxic or nutrient concern. The lack of knowledge of the phase associations of toxic metals in sediments is the largest deficiency in our understanding of the environmental hazard posed by metal contamination. This study examined the sedimentary partitioning...

Multi-hazard Damage and Loss Assessment of Bridge Networks

Creator:: Burns, Patrick O.
Abstract:: The overarching objective of this study is to examine and compare the vulnerabilities of bridges combining effects of earthquake-induced ground shaking, ground failure (e.g., landslides and lateral spreading), and tsunami inundation. A parametric study is performed to understand the sensitivity of economic loss and traffic capacity with respect to the...

Absorption of chlorophenols on granular activated carbon

Creator:: Yang, Maoyu
Abstract:: Studies were undertaken of the adsorption of chlorinated phenols from aqueous solution on granular activated carbon (Filtrasorb-400, 30x40 mesh). Single-component equilibrium adsorption data on the eight compounds in two concentration ranges at pH 7.0 fit the Langmuir equation better than the Freundlich equation. The adsorptive capacities at pH 7.0 increase...

Adsorption of hexavalent and trivalent chromium to a clayey silt soil : batch kinetic and equilibrium studies

Creator:: Bean, Gregory R.
Abstract:: Chromium, an element of widespread use, is toxic in some forms. Improper disposal of waste chromium products has resulted in contamination of many sites throughout the United States, including the United Chrome Products Superfund site in Corvallis, Oregon. A better understanding of chromium chemistry is needed to facilitate the remediation...

The Effects of Temperature on Electrical Resistivity Measurements of Concrete

Creator:: Coyle, Alex T.
Abstract:: Measuring resistivity as a method to calculate formation factor is becoming a popular way to evaluate transport properties of concrete. Resistivity measurements are dependent on multiple factors including the resistivity of the pore solution, leaching effects, the degree of saturation of the specimen, the age of the specimen (degree of...

Application of quality function deployment in the conceptual design of a construction project

Creator:: Hinkle, Verda O.
Abstract:: Quality Function Deployment (QFD) is a product development process that assures the needs and desires of the customer are heard and heeded during the design, development and production of a product. Though it has been used successfully in other industries, only a few companies in the U. S. Engineering and...

Development of a priority rating system for highway safety improvements

Creator:: Iranitalab, Farhad
Abstract:: This thesis presents the procedure adopted to develop the priority rating system for highway safety improvements. Safety hazards are classified into four categories: (1) Railroad crossings, (2) Intersections, (3) Geometric-Related Hazards, and (4) Roadside Hazards. For each category of hazards, relationships are developed to obtain a hazard index and expected...
