Lidar-Assisted Extraction Of Old Growth Baldcypress Stands Along The Black River Of North Carolina, Weston Pierce Murch
Graduate Theses and Dissertations
The remnants of ancient baldcypress forests continue to grow across the Southeastern United States. These long lived trees are invaluable for biodiversity along riverine ecosystems, provide habitat to a myriad of animal species, and augment the proxy climate record for North America. While extensive logging of the areas along the Black River in North Carolina has mostly decimated ancient forests of many species including the baldcypress, conservation efforts from The Nature Conservancy and other partners are under way. In order to more efficiently find and study these enduring stands of baldcypress, some of which are estimated to be more than …
Baha’I Sacred Architecture And The Devolution Of Astronomical Significance: Case Studies From Israel And The Us, Michael Steven Meizler
Baha’I Sacred Architecture And The Devolution Of Astronomical Significance: Case Studies From Israel And The Us, Michael Steven Meizler
Graduate Theses and Dissertations
Sacred architecture is a complex conglomerate of different ideals of a faith. Within modern terms, the Baha’i faith is an excellent example of modern sacred architecture. Within ancient times the architecture of temples and shrines oftentimes had celestial alignments meant to connect the adherent to the gods. With this in mind, the Baha’i faith is evaluated with the use of cartography, celestial measurements, orthophotography, and archival research to evaluate the significance of the Baha’i sacred architecture and the symbolism embedded within it. The Baha’i faith came out of Persia during the 19th century and relocated to Israel late in that …
Towards Systematic Selection Of Terrain- And Ground Cover-Specific Lidar Filtering Parameters, Vance Green
Towards Systematic Selection Of Terrain- And Ground Cover-Specific Lidar Filtering Parameters, Vance Green
Graduate Theses and Dissertations
Accurate automated classification of LiDAR point clouds is a well-known problem and proper parameterization of the classification algorithm is essential to creating useful bare-earth terrain models. Parameterization is particularly important in areas characterized by extremely low relief, such as the Little Red River Irrigation Project Area in central Arkansas. In this kind of landscape, analyses such as hydrological flow models are sensitive to small changes in the topography, and therefore prone to errors in the classification of the LiDAR point cloud and the digital elevation models (DEMs) derived from it. Developing effective project-specific parameters requires a high degree of knowledge …

Graduate Theses and Dissertations
This research assessed green space morphology in Kuwait City, explaining its evolution from 1982 to 2014, through the use of geo-informatics, including remote sensing, geographic information systems (GIS), and cartography. This research examined archival and contemporary satellite images that show the distribution, size, amount, and type of green spaces in Kuwait City, within the framework of its surrounding urban, exurban, and suburban expansion, and landuse change. Through this integrated analysis, it was found that green space growth passed through three main stages: Early Stage, Growth Stage, and Stable Stage.
This study also examined the effective use of public parks and …
Mapping Ancient Baldcypress Forests For Conservation At Black River, North Carolina, Jordan Nichole Burns
Mapping Ancient Baldcypress Forests For Conservation At Black River, North Carolina, Jordan Nichole Burns
Graduate Theses and Dissertations
A few ancient baldcypress-bottomland hardwood forests survive across the southeastern United States in a mosaic of remnant old-growth stands left untouched by extensive logging during the early 20th century. Uncut stands in the Southeast that survived centuries of disturbance following European settlement tended to be too senescent and non-commercial to justify logging. Remnant ancient baldcypress forests at Black River, North Carolina, appear to contain the oldest living trees in eastern North America and The Nature Conservancy has protected several of these stands. However, the full extent of ancient bottomland forests along Black River is not known and many valuable tracts …
Local Food And Agriculture Awareness: The Literacy Of Local Produce And Agriculture In Northwest Arkansas, Kyle Colton Flynn
Local Food And Agriculture Awareness: The Literacy Of Local Produce And Agriculture In Northwest Arkansas, Kyle Colton Flynn
Graduate Theses and Dissertations
The Center for Disease Control and Prevention (CDC) suggests that adolescents and children, both male and female, are failing to meet the daily fruit and vegetable consumption requirements (Kim et al., 2011; Upton et al., 2012; Harris et al., 2012). Other studies have shown that with increased exposure and availability of produce, students (K-5) tend to consume more fruits and vegetables (Cullen et al., 2009; Evans et al., 2012). The purpose of this study is to identify whether Northwest Arkansas eleventh grade high school students possess experience and knowledge of local produce and agriculture. Out of 1054 students enrolled at …

Landscape History In The G.K. Warren Missouri River Maps, Graham Alan Callaway
Graduate Theses and Dissertations
In 1855 and 1856, military surveyor Gouverneur K. Warren and his assistants produced what was at the time the most accurate map ever made of the Missouri River. This series of highly detailed sketch maps records numerous cultural features and an extraordinary level of environmental detail, making it an invaluable resource for research on the history of the region. This paper represents the first attempt to comprehensively interpret the content of these maps, identifying the features recorded where possible and assessing the probability of archaeological preservation of those not previously known. A subset of the recorded environmental data, from roughly …
Role Of Vegetation And Environmental Characteristics On Slope Stability In Northwest Arkansas, Michael Maguigan
Role Of Vegetation And Environmental Characteristics On Slope Stability In Northwest Arkansas, Michael Maguigan
Graduate Theses and Dissertations
Slope failure continues to pose risks to society because knowledge of environmental factors and their interactions are unclear and possibly misunderstood. This misunderstanding leads to generalizations about slope failure susceptibility mapping, despite knowing that slope failures are likely the result of an extensively complex set of interactions among a number of environmental, edaphic, and geomorphic characteristics. Therefore a series of experiments were conducted to investigate the effects of slope, soil texture, vegetation cover, bedrock permeability, and compaction,. A wooden flume with a slope face 1 m wide by 1.5 m long with a 10 cm toe was constructed to contain …
