Toward New Age Modeling and Management of Nuisance Cladophora in the Great Lakes
Monday, November 2, 2015
202 Great Lakes Research Cener
Anika Kuczynski, Ph.D. Candidate, Department of Civil & Environmental Engineering, Michigan Tech
A native to the Great Lakes, Cladophora glomerata is a filamentous, green alga that has proliferated and caused nuisance conditions especially in the lower Great Lakes, both historically and in the 21st century. Depending on currents affected by wind speed and direction, algal mats may clog cooling and drinking water intakes or wash up on beaches. The decaying plant material produces offensive odors and provides favorable environmental conditions for hosting pathogens. While Cladophora was not the target for P abatement, which began in the late 1970s, its biomass levels appeared to decrease by the early to mid-1980s in Lake Ontario. With the return of nuisance conditions since the zebra and quagga mussel invasion and an altered system at hand, current field monitoring and modeling efforts are necessary to establish a new baseline understanding and appropriate management approaches in this new age. The objectives of this dissertation will be 1) to establish that there has, in fact, been a Cladophora resurgence in the Great Lakes and to quantitatively characterize that resurgence and management implications, 2) to define a phosphorus standard or substance objective for Cladophora management in the Great Lakes; and to demonstrate the application of linked hydrodynamic-phosphorus-Cladophora modeling to define management strategies in two case studies, 3) the Ajax, ON nearshore of Lake Ontario and 4) the eastern basin of Lake Erie.
Title: A Tale of Two Careers in the Same Field
By: Dr. Kerry J. Howe, P.E., BCEE
Completing a graduate degree in civil and environmental engineering opens the door to a variety of career paths: government agencies, consulting firms, universities. Dr. Howe has worked extensively in two of these arenas. First, as a design engineer for the engineering firm that is now Montgomery Watson Harza. After a 12-year stint there, he completed a PhD degree and starting working as a professor at the University of New Mexico, where his research has focused on membrane technologies, desalination, and water reuse, including the use of reverse osmosis and ozone/biofiltration to treat wastewater for water reuse applications. This presentation will use case studies from his career to describe a typical design project done by consulting engineers and a typical research project at a university. The presentation will then describe the skills needed by civil and environmental engineers in both career paths, and describe the similarities and differences between consulting engineers and academicians.
Dr. Howe is a professor and regents’ lecturer at the department of civil engineering, University of New Mexico. Dr. Howe is also a registered professional engineer (P.E.) and a board certified environmental engineer (BCEE) by the American Academy of Environmental Engineers. Prior to studying for his doctorate degree at University of Illinois at Urbana-Champaign Environmental Engineering, Dr. Howe worked for environmental engineering consulting firms for more than 12 years. During his time in consulting, he worked as project engineer or project manager on a wide variety of projects related to water treatment engineering, including treatability studies, regulatory compliance evaluations, facility evaluations, master plans, pilot studies, predesign, detailed design, construction management, and plant startup. His practical engineering experience has a strong influence on his research and teaching activities. He is a co-author of the textbooks Principles of Water Treatment and MWH’s Water Treatment: Principles and Design. Dr. Howe is a director for Center for Water and the Environment from the National Science Foundation Centers for Research Excellence in Science and Technology (CREST) program.

Biography – I am a PhD student in Environmental Engineering with focus on air pollution. studying Environmental Engineering, I could see how air pollution had surrounded millions of people and it seemed policy makers were incapable. Picturesque Alborz hillsides, in which Tehran (Capital City) is located, were lost in smog. In the last 3 years, up to 7000 deaths in Tehran are caused by Airborne Particles. As a part of my research I have investigated the effects of air pollution of a steel complex -a case study- on surrounding area using air pollution dispersion modeling (AERMOD and CMB8.2); I have then investigated concentrations of PM10 in ambient air and Arsenic in air, water, soil, rice and meat downstream of the steel plant. In addition, I have studied lifetime risk assessment of Arsenic due to inhalation, ingestion and dermal exposure for residents.
Environmental issues regarding air pollution in Iran include, especially in urban areas, vehicle emissions, refinery operations, huge dust swirl from Iraq and industrial effluents which contribute to poor air quality. Industrial nature and the status of its environmental issues, regulation and management in Iran will be presented to expand the world vision of a developing country.

Biography – I am an environmental microbiologist who studies microbial communities in diverse ecosystems. Microbes (Bacteria and Archaea) are ubiquitous in the environment and play essential roles in the cycling of elements. These environmental microbes are capable of catalyzing a wide array of chemical reactions, many of which may have industrial applications. I study how complex microbial communities can cooperate to perform functions of industrial interest. The majority of microbes in the environment are difficult to grow in the lab. Furthermore, many industrially-relevant pathways are found in microbes not yet grown in the lab. I seek to employ both culture-based and culture-independent methods to understand how these microbial communities respond to anthropogenic activity and environmental change and how we might leverage these microbes for a biotechnological application. In the past, I have investigated how microbes from hot springs and geothermal vents could be used for biofuel production. Most recently, I have focused on microbial communities that respond to and aid in the clean up of crude oil contamination. I am also interested in engineering environmental microbes and microbial communities for enhanced biofuel production. I employ a combination of geochemical techniques, next-generation sequencing and other ‘omics approaches, with microbial physiology and biochemistry to better understand these microbial systems.

Title: Creating Educational Materials for Python and GIS
Author: Shelley Jeltema, PhD student in Civil/Environmental Engineering
Room 642 Dow, 4:05 – 4:55 pm, Thursday, April 2.
This project created a 15-week course to teach graduate students and GIS analysts/technicians how to use Python to extend the functionality of Geographical Information System (GIS) software. Using a combination of traditional college course and corporate training methods results in a modular course that can be taught in a traditional college setting, online, or as a custom course for specific business purposes. The class is comprised of lectures and labs where students will learn scripting, data processing with Python. Students will also learn how to create ArcGIS models with Python Script. The course contains base set of labs will focus on natural resource management and hydrology. Additional labs will cover different business scenarios to expand the audience to business, surveying, social science, and Peace Corps students. At the end of the course, students will have gained experience in scripting, data pre-processing, and modeling with Python and AcrGIS. They will also have frameworks for real world business scenarios. The requirements for this class are prior experience with ArcGIS and familiarity with modeling. Computer coding experience is suggested but not recommended. Future work includes continued refinement of this course to include more of the skills businesses. An advanced course teaching concepts and techniques that create more complex models using computer programs, creating ArcGIS tools, and working with GIS in a distributed computing environment where workload balancing is available.

Integrated LCCA and LCA of Road and Rail Freight Transport
Freight transport occurs between nearly any two process steps of a product system and is often of major importance for a product life cycle. The transportation sector accounted for 28% of the total greenhouse gas emission in the US in 2012 and it is forecasted to account for 63 percent of the total growth in global consumption of petroleum and other liquid fuels between 2010 and 2040. For these reasons, it’s essential that the development of new freight transportation lanes and activities takes a holistic approach in the evaluation of alternatives where energy consumption and emissions are minimized throughout the project life cycle. This project takes steps towards that goal by applying the Life Cycle Assessment (LCA) and Life Cycle Cost Analysis (LCCA) methodologies for comparing road, rail and road-rail multimodal transportation alternatives for freight shipment.
The main objectives of this study is to analyze all the costs and emissions during phases of construction, operations, maintenance and final salvage or recycling stage of both the infrastructure and the equipment that are used over a variable life time of freight transport process of road and rail modes. The emissions are then converted to cost values (using potential unit costs of emissions) for integration with LCCA for overall assessment.
This presentation will give an introduction to LCA and LCCA and its past applications in transportation sector. The presentation will also talk about a case study for which LCA and LCCA will conducted for movement of ore between a proposed mine and refinery in the Upper Peninsula (Copperwood Mine project) and the movement of refined concentrate between the refinery and Escanaba, MI.

Title: The Effects of Climate Change on Sediment Transport and Bridge Scour
Global climate change is expected to influence rivers and streams. As a result, both human use of rivers and ecological health become a growing concern. As rainfall intensifies and river flows increase, sediment mobilizes and the potential for blocked harbors, induced flooding, bridge scour, and fish habitat disturbance also rise. Our research objectives are to quantify the effects of rainfall intensity and water temperature on sediment transport. In an effort to gain a better understanding of sediment dynamics six models were analyzed. By developing a relationship between flow, temperature, and sediment loads, we aim to develop a useful tool for river and bridge engineers to plan for sediment management. The relationship developed can be a means to help 1) identify vulnerabilities of rivers to climate change, 2) prioritize distribution of financial resources, and 3) guide water resource managers to develop adaptive management strategies.
