This research identifies the well components, operation factors, and the soil and hydrogeological parameters that influence the recovery of Light-Non-Aqueous-Phase-Liquids (LNAPL) in an heterogeneous environment using pumping wells. The purpose of this research is to improve the analysis of sites contaminated by LNAPLs to efficiently recover the feasible amounts of LNAPL in the sites. The focus is on heterogeneous soil environments. The model adapted to analyze the recovery of LNAPL from the contaminated sites was improved to account for a high degree of vertical heterogeneity, including the vertical variation of one or several of the soil properties within the same layer. This research also studies the optimization of the recovery of LNAPL for the system of wells both at the level of one well and a system of wells. The developed model and method are applied to a real site. Thus, the model’s ability to estimate the performance of a system of recovery wells is evaluated using real soil data and performance measurements. This research constitutes a robust background regarding the design, operation, analysis, and optimization of a system of recovery wells in a heterogeneous soil environment. / text

Master of Landscape Architecture / Department of Landscape Architecture/Regional and Community Planning / Melanie F. Klein / Cities and nature are often popularly viewed as polar opposites. Many American cities are seen as “destructive of nature, gray and natureless, distinct and separate from natural systems” (Beatley 2008, 189). Cities lacking in ecological functions can benefit from the application of Green Urbanism theory. Green Urbanism incorporates ecological features as central design elements, cities, and to restore, nurture, and celebrate urban ecology. Unique ecological features can affect a place in positive ways while adding and establishing an identity for the city. One city that has been stuck in a gray and natureless state is St. Louis, Missouri, in particular, the Central business district. In order to transform St. Louis into a more ecologically rich city, an eco-boulevard will be implemented. An eco-boulevard is a green ribbon that collects stormwater runoff and connects people to surrounding local amenities. In addition to stormwater benefits, the eco-boulevard will serve as a visual and physical connector for pedestrians to public destinations, and connect pedestrians with other pedestrians by serving as its own destination. The eco-boulevard can also provide multiple ecological and social benefits to promote healthy places with a high quality of life. In order to achieve the implementation of an eco-boulevard, a thorough analysis of watersheds, key low points, transportation hubs, public destinations, and established pedestrian traffic routes were considered. The design of the eco-boulevard is concentrated in areas where low points in elevation, transportation hubs, public destinations, and highly traveled pedestrian traffic routes converge. At the intersection of these elements, unique features capture and store stormwater runoff. As a whole, the entire eco-boulevard improves urban ecology through the use of vegetation, street trees, and the recycling of water.

Master of Regional and Community Planning / Department of Regional and Community Planning / John Keller / This report examines the evolution of the Federal Emergency Management Agency. Processes and procedures have evolved overtime and the agency is making strides in improving their reputation. Joplin, Missouri, is used as a case study to determine (1) if there are changes being made in the Federal Emergency Management Agency and (2) outlines the process to receive aid after a natural disaster. Interviews were conducted with officials and members of the public who worked with the Federal Emergency Management Agency after the disaster and their impression of the agency was documented.

Master of Regional and Community Planning / Department of Landscape Architecture/Regional and Community Planning / Huston Gibson / In 2011, the United States Secretary of the Interior approved a proposal for expansion of the Harry S. Truman National Historic Landmark District in Independence, Missouri. The expansion of the historic district and the subsequent press resulting from the expansion was the inspiration for this report. The topic area of this report is historic preservation. Historic districts come with increased rules and regulations that can be seen as limiting a resident’s use of the properties within these districts. This report is concerned with the actual condition within a historic district with a central hypothesis that historic districts do have a positive association with property condition. In order to answer the research question, a multiple-case replication explanatory case study was performed using the original landmark district boundaries and two comparable nearby neighborhoods outside of the historic landmark district. The case study utilized secondary sources and in-field observations to analyze seven researchable factors about the parcels within the study areas. These factors were compared and contrasted during the cross case analysis. To further the understanding of the study area, a detailed profile of the City of Independence, Missouri, was produced. This profile looked at the historical development of the city, as well as economic and demographic statistics. The theoretical framework behind historic districts was also analyzed for this report. It is beneficial to look at this question in order to evaluate the potential implementation of a historic district that a planner may face in their municipality such as whether historic preservation regulations should be maintained, expanded, or eliminated or a historic district should be put in place. The report ends with a conclusionary chapter including recommendations, lessons for planning professionals, and ideas for further research.

We describe methods and progress in developing the American Long Oak Chronology (ALOC), an effort to construct an oak tree-ring chronology from the Central US that spans the Holocene. Since 2000, we have collected and measured ring widths on over 550 pieces of subfossil oak (Quercus) wood. Over 330 oak samples have been radiocarbon dated, with ages ranging up to 14,000 cal yr B.P. A 1,093- year-long tree-ring record has been constructed from live and subfossil bur oaks (Q. macrocarpa Michx.) and swamp white oaks (Q. bicolor Willd.) growing along and buried in sediments of streams that flow through northern Missouri and southern Iowa, USA. Here we describe the ALOC for the period A.D. 912–2004 to demonstrate its dendrochronological value, display the material quality, and emphasize the importance of chronology construction. We also report on progress in developing older floating chronologies. The development of more long, multi-millennium chronologies will be an important contribution to dendroclimatology. These chronologies will be particularly useful to the Central US, a region with a continental climate and limited temporal depth of annually resolved paleorecords. Perhaps more critical is its location in the middle of one of the most important agricultural regions in the world.
