Dissertations, Master's Theses and Master's Reports

Management of wastewater treatment plants (WWTPs) has been found to be especially challenging in small, rural communities of the developing world. This study examined maintenance of two small WWTPs in Leymebamba and Palmira, Peru through interviews with local authorities, observation of maintenance practices, wastewater measurements, and prediction of effects from maintenance with modeling using a wastewater process simulation software, BioWin. Challenges and motivations related to maintenance were investigated with semi-structured interviews, and maintenance practices were recorded during observations. It was found that outside supervision was a key motivating factor, and the existence of an operator who is supported by the …

Development Of A Fundamental Rating System For Identifying Sprawl: A Case Study Utilizing Small Cities In Michigan, Jonathan T. Riehl

Dissertations, Master's Theses and Master's Reports - Open

Urban sprawl research generally fits into one or more of four realms including definitions, causes, components, and consequences. Although research on consequences continues to thrive, research on components is in its adolescence, primarily due a lack of consensus on definition. Recent studies such as Ewing et al. 2014 have narrowed the list of sprawl metrics to about 20 within four factors including development density, land use mix, activity centering, and street accessibility.

This main product of this research is a Sprawl Scorecard for small Michigan cities varying in size from Traverse City, nearly 50,000 people in the urban cluster, down …
