He also gave the presentation September 9, for the Civil Engineering Seminar Fisher 10 at 7 p.m. in conjunction with the Railroad Engineering and Activities Club’s first general business meeting

The title of the seminar is: “Railway Track Structures Research at Tampere University of Technology”

The Railway Track Structures Research Team at Tampere University (TUT) of Technology consists of about 10 researchers. The research area includes track components from subsoil stability through the structural layers to sleepers, rails and wheel-rail contact. Essential parts of the research area are also bridges and the life cycle and monitoring of track structures. The main emphasis of activity is experimental research based on diverse arrangements from laboratory scale material analyses to field measurements and full-scale loading tests. Research methods are complemented by calculation analyses of performance of structures and literature reviews of international research results. The basis of the on-going track structure research is the Life Cycle Cost Efficient Track research programme (TERA) implemented in co-operation with the Finnish Transport Agency. This presentation provides an overview of research projects conducted at the TUT and related outcomes.

Environmental Engineering Seminar: Nuts and Bolts of Unconventional Oil and Gas Development

Nuts and Bolts of Unconventional Oil and Gas Development
including all you might like to know about the technology and practice of hydraulic fracturing
Wayne D Pennington, Interim Dean, College of Engineering, Michigan Technological University
Mon Mar 24, 2014 3pm – 4pm, Dow 642

Over the past couple of decades, technology has been developed to produce oil and gas from geological formations that had been overlooked previously due to the lack of appropriate engineering techniques for those types of formations. As a result, the energy picture for the USA and for the world has been seriously modified, and the impact is being felt.
These “unconventional” deposits contain hydrocarbons in significant quantities, but they were locked up in microscopic pores that were at best poorly connected to each other, limiting or preventing flow through the rocks. Existing technologies, such as hydraulic fracturing (in use since 1948) and extended-reach horizontal wellbores were used independently, and then merged, for a highly successful, efficient, and safe method of oil and gas production.
The geologic formations, and the production techniques used in each, that are described in this presentation include: (a) “tight” gas sandstone deposits (produced through multiple-stage hydraulic fracturing in vertical wells); (b) coal deposits (methane produced by drawing down water pressure to release gas from the coal structure; also the source of many “flaming faucets” from domestic water-wells); and (c) shale deposits (generally using multiple-stage hydraulic fracturing in horizontal wells).

Environmental Engineering Seminar: Lake Superior Topics

“Hydrodynamics and Thermal Structure in Lake Superior Impacts of an Episodic Climate Anomaly”

In recent years, 3D hydrodynamic models have been widely applied in a predictive capacity to all the Great Lakes to study ecosystem response to long-term climate change. But, an alternative aspect of climate change, observed as intermittent climatic anomalies, has not received equal interest. An isolated, positive anomaly observed in local air temperature measurements in March 2012 presents a unique opportunity to study the latter in Lake Superior’s ecosystem. Here, a 3D hydrodynamic model, Environmental Fluids Dynamics Code (EFDC), is applied for two consecutive summers, one preceded by the spring anomaly (2012) and the second preceded by average spring air temperatures (2011), to analyze the impact of this climatic anomaly on the thermal regime of the lake. This modeling effort is supported by a rich, comprehensive dataset of surface water temperatures and vertical temperature profiles measured during the April to September period of 2011 and 2012. Impacts of the temperature anomaly were observed along temporal and spatial scales; e.g. the 6°C increase in lake-wide surface water temperatures at the start of summer 2012 as compared to 2011 as well as on the physical processes; e.g. an early onset of thermal stratification (4 weeks in advance) in 2012. These shifts in thermal regimes will in turn affect ecological processes.

“Ecosystem function in Lake Superior: Impacts of an episodic climate anomaly”

Climate change may become manifest over differing time scales: one characterized by long term, incremental changes as recorded in historical averages and the other by short term variability, e.g. the magnitude, timing, frequency and duration of episodic, extreme events. The ecological impact of extreme weather events may be particularly severe, simply because they are extreme, but also because ecosystems have rarely been exposed to such events. Due to the inherent unpredictability of extreme events, few studies have reported on the attendant ecosystem response. Here, the effects of an episodic air-temperature anomaly that occurred in Spring 2012 are reported and compared to those of 2011, a year with essentially average temperature conditions. Impact of this extreme weather event on the lake’s thermal regime and ecological forcing conditions (e.g. light, temperature and nutrients) cascaded through the system. This resulted in elevated annual primary production with a distinctive temporal distribution characterized by high productivity in early summer followed by a collapse in September (brought on by nutrient depletion resulting from extended thermal stratification). The benefits of increased annual primary production to the higher food web may be offset by cataclysmic drops in production.

Title: Great Lakes Water Level Regulation and Diversions
Cynthia Jarema, P.E., U.S. Army Corps of Engineers, Detroit District

Abstract:
The Great Lakes are a hydraulically regulated system. The Boundary Waters Treaty of 1909, established a commission between the U.S. and Great Britain (Canada), so that joint decisions could be made regarding issues and projects such as hydropower and diversions in the Great Lakes. Individual Boards of Control acknowledge and focus on the needs of various interest groups in their respective area. The International Lake Superior Board of Control operates a technical regulation plan to determine the Lake Superior outflow rate that would bring the levels of Lake Superior and Lakes Michigan and Huron to the same relative position within their respective historical ranges, before diversion or control structures were in place. The ability to regulate Lake Superior’s outflow however, does not mean that full control of lake levels is possible. Meteorological occurrences (precipitation, evaporation, and runoff) cannot be controlled or accurately predicted, and has a much greater impact to water levels than any man-made control.
