1. Murali, Bharathi. Comparison of the recovery of Bacillus anthracis and Bacillus thuringiensis spores from porous media : considering time and moisture content.

Degree: 2014, Michigan State University

Thesis M.S. Michigan State University. Biosystems Engineering - Master of Science 2014.

Bacillus anthracis spores are agents used for biological warfare owing to high virulence, and extreme resistance to environmental stresses with negligible degradation in viability. There is an interest in understanding the persistence and subsequent health risks due to B. anthracis spores in the indoor environment during bioterror attacks, but neither the time-dependent behavior of B. anthracis spores on porous media nor the suitability between B. anthracis and its recommended experimental surrogate, B. thuringiensis spores, are well known. This work specifically focused on recovery of B. anthracis and B. thuringiensis spores from HVAC filters, a porous fomite, considering the effects of sampling time and moisture content using culture-based quantification. Effects of time significantly affected the recovery of Bacillus spores. Although there was an overall reduction in viability of Bacillus spores over time, the reduction in recovery of B. anthracis and B. thuringiensis varied remarkably. Clumping in B. thuringiensis spores and accelerated dehydration rates at higher moisture levels might have resulted in increased observed recovery of B. thuringiensis. Hence it is concluded that, B. thuringiensis spores is not an ideal experimental surrogate for B. anthracis in recovery studies. Inclusion of time and moisture emphasizes the importance of variation in recoveries and inferences between the surrogate and B. anthracis spores. The data generated in this study will be useful for persistence studies that measure reduction or decay but are dependent on recovery. Furthermore, this information will inform quantitative microbial risk assessment (QMRA) models that estimate the risk of exposure to B. anthracis spores in indoor environments.

2. Novaes, Valerie. Assessing the impacts of post-construction best management practices on stormwater runoff in an ultra-urban environment.

Degree: 2015, Michigan State University

Thesis M.S. Michigan State University. Biosystems Engineering 2015

The effects of urbanization on water resources in the United States and around the world have been well documented by scientists and engineers. Traditional storm sewer systems coupled with detention basins have historically been implemented to mitigate the increased stormwater runoff volume and peak flow rates from urbanized areas. However, this solution has been found to exacerbate the problems associated with increased peak flow rates and runoff volumes in the receiving streams by extending the duration of bank-full flows. Future effectiveness of addressing urbanization must seek to mimic the natural hydrologic processes that occurred prior to urbanization. Low Impact Development is an alternative approach to sewer systems that has been implemented to promote the natural hydrologic processes including evaporation, infiltration, and transpiration. However, detailed full-scale water quantity performance data is scarce. To address this knowledge gap, the following research objectives were developed: (1) evaluate the influential factors that impact infiltration rate in engineered soils, (2) determine the relation between the percentage of unfilled pore space, soil compaction, and plant health, (3) analyze the overall health of the planted community, and (4) evaluate how the bioretention systems have modified the surface runoff hydrograph with respect to change in total volume, the time to peak, the peak flow rate and the overall shape of the runoff hydrograph. An EPA SWMM model was developed to analyze the Michigan Avenue bioretention facilities. Results indicate that a viable alternative exists to the conventional stormwater drainage system that provides substantial reductions in runoff volume, peak flow rates, and increase the time of concentration while changing the overall shape of the runoff hydrograph. Additionally, improvements in data collection and performance testing were provided.

3. Esfahanian, Elaheh. Development of a meteorological, agricultural, stream health, and hydrological (MASH) comprehensive drought index.

Degree: 2016, Michigan State University

Thesis Ph. D. Michigan State University. Biosystems Engineering 2016.

Droughts are one of the costliest of natural disasters, posing a significant threat to both man-made and natural systems. Hundreds of drought indices are currently available for the monitoring of drought magnitude, severity, and extent; however, most of these indices were primarily designed for the analysis of drought’s impact on human concerns, such as crop production and freshwater supplies, and do not consider greater environmental aspects such as stream health. To the best of my knowledge, no universal drought index has been developed with the ability to comprehensively quantify different aspects of drought (e.g. meteorological, agricultural, hydrological, and stream health). In addition, there is no general agreement for drought definition even within each drought category. This means that different drought indices, even in the same category, can report contradictory results. In order to address these issues, we designed a study based on the following research objectives: 1) development of an index capable of determining the impact of drought on aquatic ecosystems and stream health; 2) creation of a universal drought index for the measurement of multiple impacts of drought (e.g. meteorological, hydrological, agricultural, and stream health); and 3) determination of a predictive drought model that is able to capture both the categorical and overall impacts of drought. To address the first objective, we coupled a soil and water assessment tool (SWAT) with a regional-scale habitat suitability model to investigate drought conditions in the Saginaw River Watershed. Using the ReliefF algorithm as our variable selection method along with partial least squared regression, six predictive stream health drought models were developed to monitor stream health drought conditions. Of these models, the version with five flow-related variables was determined to be the best tool for predicting both stream health and drought severity. For objective two, thirteen commonly used drought indices from the following categories were integrated to devise a definition of drought that is both categorical and universal: meteorological (4 indices), hydrological (4 indices), agricultural (4 indices), and stream health (1 index). The three closest indices to each other in each category were selected and then averaged to obtain the categorical drought scores; next, the simple average method was used to aggregate the categorical scores, which then provided the universal drought score. For objective three, the ReliefF algorithm was used to select the best variable set for each of the categorical drought scores as well as for the universal drought score. The highest ranked variables were then used in the development of the various predictive drought models via the adaptive network-based fuzzy inference system. The adaptive network-based fuzzy inference system successfully produced four predictive drought models, including the three categorical models (meteorological,…
