Estimation Of Parameters For Calibration And Validation Of Monochlorobenzene Flux, Christina Hill

Electronic Dissertations and Theses

Research is currently being conducted to enhance the existing pump-and-treat remediation strategy at the Petro Processors, Incorporated site (PPI)-a petrochemical disposal site consisting of two locations in East Baton Rouge Parish (Louisiana). Monochlorobenzene, a biodegradation byproduct of hexaclorobenzene, is a toxic chemical prevalent at the site; the diffusivity of monochlorobenzene is being studied through desorption experiments. The objective of soil desorption experiments is to determine soil-water distribution or partition coefficients. Partitioning is the distribution of solutes between two phases such as solid phase and a liquid (aqueous) phase. The derivation of acceptable partition coefficients "are used in [models] to determine …

Comparison Of One-Dimensional And Two-Dimensional Hydrodynamic Modeling Approaches For Red River Basin, Sajjad Ahmad, Slobodan P. Simonovic

Civil and Environmental Engineering and Construction Faculty Research

EXECUTIVE SUMMARY

A devastating flood in Red River valley in 1997 emphasized the need to study the flood control measures in the Red River basin using state of the art modeling tools. The Red River and its floodplains can be modeled using one-dimensional, quasi two-dimensional or fully two-dimensional hydrodynamic models. Each modeling approach has its own advantages and limitations. The main purpose of this report is a comparison between one-dimensional (or quasi two dimensional) and fully two-dimensional hydrodynamic modeling approaches for modeling floods in the Red River basin.

A two-dimensional hydrodynamic model, MIKE 21, coupled with Geographic Information System (GIS) …

Boundary Control For Automated Sweeping Of Finite Element Meshes, Robert A. Kerr

Theses and Dissertations

Finite element analysis depends greatly upon a high-quality mesh to be able to provide reasonably accurate answers to engineering problems. Models that need to be analyzed using finite element analysis are becoming increasingly more complex, and correspondingly harder to mesh with good quality. Skew is one quality metric which can cause problems with finite element analyses. This thesis explains how skew is calculated, discusses two common sources of skew: multiply-linked surfaces with interval constraints, and biased edge meshes. Two methods of lessening skew in surface meshes are then presented: the skew control algorithm, and the curve morphing algorithm. These algorithms …

Lead Binding To Metal Oxide And Organic Phases Of Natural Aquatic Biofilms, Yarrow M. Nelson, Leonard W. Lion, Michael L. Shuler, William C. Ghiorse

Civil and Environmental Engineering

The role of the composition of surface-coating materials in controlling trace metal adsorption in aquatic environments was investigated using natural biofilms that developed on glass slides in three New York State lakes and a water-supply well. Adsorption isotherms were obtained for Pb binding to each of the biofilms in solutions with defined Pb speciation at 25°C and pH 6.0, with Pb concentrations ranging from 0.2 to 2.0 μM. Adsorption isotherms for Pb binding to laboratory-derived metal oxides and surrogate organic materials were determined under the same conditions. These isotherms, combined with characterization of natural biofilm composition, were used to estimate …

Capacity‐Demand‐Diagram Methods Based On Inelastic Design Spectrum, Anil K. Chopra, Rakesh K. Goel

Civil and Environmental Engineering

An improved capacity‐demand‐diagram method that uses the well‐known constant‐ductility design spectrum for the demand diagram is developed and illustrated by examples. This method estimates the deformation of inelastic SDF systems consistent with the selected inelastic design spectrum, while retaining the attraction of graphical implementation of the ATC‐40 Nonlinear Static Procedure. One version of the improved method is graphically similar to ATC‐40 Procedure A whereas the second version is graphically similar to ATC‐40 Procedure B. However, the improved procedures differ from ATC‐40 procedures in one important sense. The demand diagram used is different: the constant‐ductility demand diagram for inelastic systems …

Investigation Of Feasible Pavement Design Alternatives For Wisdot, James Crovetti, Sam Owusu-Ababio

Transportation Research Center: Feasible Pavement Design Alternatives

The current pavement design and selection process of WisDOT for all new pavements or reconstructions of existing pavement structures provides for the design of one asphaltic concrete (AC) and one portland cement concrete (PCC) pavement alternative. Life-cycle costs analyses are then used to determine the preferred alternative for construction. Previous restrictions in the WisDOT pavement selection process have essentially excluded the construction of thick AC (AC thickness > 150 mm) and thin PCC (PCC thickness < 225 mm) pavements and thus the validity of current life-cycle cost inputs for these pavement types is under question.

This report presents a performance analysis of existing thick AC and thin PCC pavements constructed in and around Wisconsin. The performance trends developed indicate current design …

Evaluation Of Superpave In Kentucky, L. John Fleckenstein, David L. Allen, Richard Reitenour

Kentucky Transportation Center Research Report

Approximately 93 percent of all pavements in the United States are surfaced with hot-mix asphalt (HMA). For many decades, most asphalt pavements were designed using the Marshall mix design method. In 1987, the Strategic Highway Research Program was established with 50 million dollars being allocated for asphalt pavement research. From that research, a new asphalt mix design procedure, called Superpave, was developed. Many states have adopted, or are in the process of adopting, this procedure, including Kentucky. In 1995, Kentucky placed its first Superpave mixture on KY 676 in Franklin County. In 1998, the Kentucky Transportation Cabinet requested that the …
