The Fathead Minnow In Aquatic Toxicology: Past, Present And Future, Gerald T. Ankley, Daniel L. Villeneuve

United States Environmental Protection Agency: Publications

This paper reviews the roles of the fathead minnow (Pimephales promelas) as a small fish model in the field of aquatic toxicology. The species has been (and is) extensively used both for regulatory testing and research, especially in North America. For example, tests with the fathead minnow, ranging from 48-h lethality through partial and full life-cycle assays, are routinely used for regulatory programs aimed at assessing potential risks of new chemicals such as high-production volume materials and pesticides, as well as impacts of complex mixtures like effluents. The species also has been used for a wide variety of …

The Role Of Energy Pipelines And Research In The United States, Cheryl J. Trench, Thomas O. Miesner

United States Department of Transportation: Publications

Energy from oil and natural gas is essential, and will continue to be essential, to all facets of our daily lives. It fuels most of our transportation needs, heats our homes, schools, offices and shops, and even generates a share of our electricity. Oil and natural gas together supply approximately two-thirds of the U.S. energy needs.

Crude oil and natural gas are generally produced in regions located far from consumption centers. This means crude oil must be moved to refineries, and refined products and natural gas must be moved from producing regions to consumption centers.

The U.S. pipeline infrastructure is …

Research Needs In Water Resources And Environment: A Panel Discussion, Otto J. Helweg, Joseph Orlins, Dale Bucks, Regan Murray, David Trueman, Raymond Walton

United States Environmental Protection Agency: Publications

Practicing engineers sometimes criticize researchers for answering questions that no one is asking, or at least for conducting research on questions of personal interest or in areas that funding agencies think are important. Although such research has a place in the overall picture of things, it is instructive to consider the practical issues that engineers in the field face. The fields of water resources and environment are very broad, and only a small number of research users could be included on the panel seated by the Education and Research Council at the 2004 World Water and Environmental Resources Congress.

Nonintrusive Mapping Of Near-Surface Preferential Flow, R. S. Freeland, Lameck O. Odhiambo, J. S. Tyner, J. T. Ammons, W. C. Wright

Department of Agricultural and Biological Systems Engineering: Faculty Publications

A unique survey protocol has been developed that maps near-subsurface preferential flow using integrated ground-penetrating radar (GPR) and a differential geographical positioning system (DGPS). The survey protocol consists of a mobile GPR system that spirals outward along a prescribed course, continuously gathering subsurface data for an extended period. Metered water is applied to a centrally located water-ponding ring, after first capturing the initial dry-state pattern signatures. The water radiates outward beneath the surface as it follows preferential flow pathways, which the GPR instrumentation spiraling above highlights. After data are collected, pre- and post-water time-elapsed images profiles are segmented by pattern …

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 …

Detection Of Inclement Weather Conditions At A Signalized Intersection Using A Video Image Processing Algorithm, Anuj Sharma, Darcy M. Bullock, Srinivas Peeta, James V. Krogmeier

Department of Civil and Environmental Engineering: Faculty Publications

Inclement weather conditions like snowfall adversely affect traffic flow characteristics, necessitating a change in parameters that define the operation of a signalized intersection. A weather-based timing plan selection is needed to maintain a desirable level of operational efficiency. Automatic implementation of weather-based timing at intersections requires accurate and timely detection of snowfall. This paper presents a snow detection algorithm that uses live video feed obtained from a video image vehicle detection system present at an intersection.

Stochastic Algorithm For Improved Operations At Isolated High Speed Intersections, Anuj Sharma, Darcy M. Bullock, Srinivas Peeta

Department of Civil and Environmental Engineering: Faculty Publications

The current practice of specifying simultaneous gap out logic at isolated high speed signalized intersections places constraints on the signal controller logic that cannot be satisfied under high congestion level. Further, it often results in degraded signal efficiency and dilemma zone protection. A stochastic approach is proposed in this paper with the objective of increasing safety and efficiency at these intersections.

Least-Squares Finite-Element Scheme For The Lattice Boltzmann Method On An Unstructured Mesh, Yusong Li, Eugene J. Leboeuf, P. K. Basu

Department of Civil and Environmental Engineering: Faculty Publications

A numerical model of the lattice Boltzmann method (LBM) utilizing least-squares finite-element method in space and the Crank–Nicolson method in time is developed. This method is able to solve fluid flow in domains that contain complex or irregular geometric boundaries by using the flexibility and numerical stability of a finite-element method, while employing accurate least-squares optimization. Fourth-order accuracy in space and second-order accuracy in time are derived for a pure advection equation on a uniform mesh; while high stability is implied from a von Neumann linearized stability analysis. Implemented on unstructured mesh through an innovative element-by-element approach, the proposed method …

Modified Log–Wake Law For Zero-Pressure-Gradient Turbulent Boundary Layers, Junke Guo, Pierre Y. Julien, Meroney N. Meroney

Department of Civil and Environmental Engineering: Faculty Publications

This paper shows that the turbulent velocity profile for zero-pressure-gradient boundary layers is affected by the wall shear stress and convective inertia. The effect of the wall shear stress is dominant in the so-called overlap region and can be described by a logarithmic law in which the von Karman constant is about 0.4 while the additive constant depends on a Reynolds number. The effect of the convective inertia can be described by the Coles wake law with a constant wake strength about 0.76.A cubic correction term is introduced to satisfy the zero velocity gradient requirement at the boundary layer edge. …

Effects Of Long-Term Wastewater Application On Chemical Properties And Phosphorus Adsorption Capacity In Soils Of A Wastewater Land Treatment System, Cong Hu, Tian Zhang, Yong Huang, Mohamed F. Dahab, Rao Surampalli

Department of Civil and Environmental Engineering: Faculty Publications

The buildup of phosphorus (P) in the soil is a major factor limiting the operating life of a wastewater land treatment system. In this study, we evaluated changes of chemical properties, P profiles, and adsorption isotherms in the soils of a Muskegon wastewater land treatment system, which has received wastewater for ~30 years. It was found that the pH in the 15-cm topsoil increased from ~5-6 in 1973 to ~7.4-7.8 in 2003; a large amount of salt (e.g., Ca, Mg) in wastewater was adsorbed by the soil; the soil Al content (either exchangeable or oxalate extractable) decreased, while the oxalate-extractable …
