Coupling Of Hydrodynamic And Wave Models For Storm Tide Simulations: A Case Study For Hurricane Floyd (1999), Yuji Funakoshi

Electronic Theses and Dissertations

This dissertation presents the development of a two-dimensional St. Johns River model and the coupling of hydrodynamic and wave models for the simulation of storm tides. The hydrodynamic model employed for calculating tides and surges is ADCIRC-2DDI (ADvanced CIRCulation Model for Shelves, Coasts and Estuaries, Two-Dimensional Depth Integrated) developed by Luettich et al. (1992). The finite element based model solves the fully nonlinear shallow water equations in the generalized wave continuity form. Hydrodynamic applications are operated with the following forcings: 1) astronomical tides, 2) inflows from tributaries, 3) meteorological effects (winds and pressure), and 4) waves (wind-induced waves). The wave …

Developing Microscopic Toll Plaza Model Using Paramics, Nezamuddin Nezamuddin

Electronic Theses and Dissertations

Simulation modeling is the most cost-effective way of studying real life transportation problems, either existing or anticipated, without disturbing the balance of the transportation system. There is a vast suite of simulation models available in market, ready to choose from macroscopic, mesoscopic, or microscopic in nature, to study different transportation system elements like freeways, highways, signalized and un-signalized intersections. However, most of these network simulation models, like PARAMICS, VISSIM, CORSIM … etc, do not come readily available with built in toll plaza models. On the other hand, many researchers have independently developed toll plaza models, which can only model an isolated …

Determination Of Ash Mixture Properties And Construction Of Test Embankment - Part B, Sungmin Yoon, Umashankar Balunaini, Monica Prezzi, Rodrigo Salgado, Nayyar Zia Siddiki

JTRP Technical Reports

Class F fly ash and bottom ash are solid residue byproducts produced by coal-burning plants. They are usually disposed off with a typical disposal rate of 80 % fly ash and 20 % bottom ash. To maximize the use of the coal ash, and thus significantly reduce the disposal problem that electric utility companies and our society in general face, the direct use of ponded or landfilled ash that is composed of high proportions of fly ash would be desirable. However, a general understanding of the behavior of high volume fly ash mixtures is needed. Although there have been investigations …

Evaluation Of Stop Bar Video Detection Accuracy At Signalized Intersections, Avery Rhodes, Darcy M. Bullock, James R. Sturdevant, Zachary Thomas Clark

JTRP Technical Reports

Many agencies nationwide have adopted video vehicle detection technology as an alternative to inductive loops. While many product evaluations have been performed, the majority of these evaluations have concentrated on freeway applications where speed and volume were the primary evaluation criteria. At an actuated intersection, the metrics of speed and volume do not necessarily represent how well a device will operate as a presence detector. Video detection was evaluated at two signalized intersections in West Lafayette, Indiana and Noblesville, Indiana. A camera on each approach was located at the vendor recommended position, at a height of 40 feet and offset …

Feasibility Study For Bicycle Safety: Data Assessment And Network Evaluation, Michael Seth Klobucar, Jon D. Fricker

JTRP Technical Reports

Technical Issues Related To The Use Of Fly Ash And Slag During Late-Fall (Low Temperature) Construction Season, Anand Krishnan, Jinesh K. Mehta, J. Olek, W. Jason Weiss

JTRP Technical Reports

The potential for scaling of concrete pavement containing fly ash is one of the durability concerns which imposes restrictions on the use of fly ash in paving applications in Indiana during the period of low temperatures (e.g., the late fall construction season). These restrictions increase the cost of paving projects, and occasionally, results in seasonal cement shortages. The objective of this study was to develop a better understanding of the scaling mechanism through a series of laboratory tests that focused on the role of material properties and length and temperature of curing in controlling scaling. Additionally, an attempt was made …

Evaluation Of Rapid Setting Cement-Based Materials For Patching And Repair, Amit D. Barde, Swathi Parameswaran, Todd Chariton, W. Jason Weiss, Menashi D. Cohen, Scott Andrew Newbolds

JTRP Technical Reports

The efficient repair and replacement of concrete pavements and bridge decks often requires a rapid setting material that can be placed, cured, and opened to traffic in a relatively short period of time. Frequently, temporary repairs are made using materials that are later found to be incompatible with the existing pavement, structures, and environment. This practice causes these materials to fail prematurely, frequently requiring re-repair. Research is needed to determine which rapid setting repair materials demonstrate the best behavior with rapid strength gain, low potential for cracking, and excellent durability. The objective of this research is to evaluate the performance …

Jointless And Smoother Bridges: Behavior And Design Of Piles, Robert J. Frosch, Voraniti Chovichien, Katrinna Durbin, David Fedroff

JTRP Technical Reports

Integral abutment bridges have been used in the United States for decades. By eliminating expensive expansion joints, the piles supporting the end bent accommodate the total thermal movement of the bridge.

Hma Pavement Performance And Durability, Eliana Del Pilar Vivar, John E. Haddock

JTRP Technical Reports

It has long been argued that at densities higher than approximately 92 percent (air void contents lower than 8 percent), a hotmix asphalt mixture is impermeable to water. However, as densities become lower (air void contents higher) than this, small decreases in the density can yield exponential increases in permeability. The objectives of this study were to better understand the increases in hot-mix asphalt pavement performance and durability that can be gained by increasing the initial pavement density and to better quantify the inter-relationship among pavement density, permeability, and moisture-induced damage. The long-term performance and durability of four hot-mix asphalt …

Flood Frequency Relationships For Indiana, A. Ramachandra Rao

JTRP Technical Reports

The objective of the research presented in this report is the development of relationships to estimate flood magnitudes for Indiana streams. In order to achieve this goal several probability distributions were evaluated. The Pearson (3) (LP(3)) and the Generalized Extreme Value (GEV) distributions were found to be the best distributions for Indiana data. Because of the requirement that Log Pearson (3) (LP(3)) distribution must be used in federally-funded projects it was retained in the study.

Relationships were developed for the flood frequencies to be estimated by the LP(3) distributions. The State of Indiana has been divided into regions, seven of …

Advanced Compaction Quality Control, Carlos Zambrano, Vincent P. Drnevich, Philippe L. Bourdeau

JTRP Technical Reports

This Synthesis Study gathered the current knowledge on the topic of Intelligent Compaction and provides INDOT with recommendations for action. It appears that totally embracing this technology at this time is premature. On the other hand, it also appears that prudent use of this technology could provide tremendous benefit-to-cost ratios over the long term and position Indiana as a leader among the States in adopting it. After examining the technological developments over the last decade it is concluded that Intelligent Compaction is a near certainty in the future. The big question is: When is the right time to begin working …

Primary Emergency Routes For Transportation Security, Srinivas Peeta, Georgios Kalafatas

JTRP Technical Reports

Security threats and natural disasters (such as hurricanes and cyclones) are events that have historically led to large scale evacuations. Evacuation operations are strongly characterized by traffic volumes that substantially exceed the network capacity, and consequently, the potential for severely degraded network performance. The efficient management of evacuations entails long-term planning and real-time operational paradigms that are, ideally, integrated. This study focuses primarily on the planning aspects of evacuation, while providing important insights for operations. Identifying capacity as a key element to efficient evacuation, the evacuation planning seeks to determine links where additional capacity is desired, as well as the …

In the 15 cm topsoil, the pH increased from &#;&#;5–6 in 1973 to &#;&#;7.4–7.8 in 2003; the soil’s total organic carbon (TOC) increased by 10–71 %; and the level of exchangeable …

Dissolution Kinetics Of High Explosives Particles In A Saturated Sandy Soil, Matthew C. Morley, Hiroshi Yamamoto, Gerald E. Speitel, Jr., Jay Clausen

Department of Civil and Environmental Engineering: Faculty Publications

Solid phase high explosive (HE) residues from munitions detonation may be a persistent source of soil and groundwater contamination at military training ranges. Saturated soil column tests were conducted to observe the dissolution behavior of individual components (RDX, HMX, and TNT) from two HE formulations (Comp B and C4). HE particles dissolved readily, with higher velocities yielding higher dissolution rates, higher mass transfer coefficients, and lower effluent concentrations. Effluent concentrations were below solubility limits for all components at superficial velocities of 10–50 cm day^-1. Under continuous flow at 50 cm day^-1, RDX dissolution rates from Comp …
