Geospatial Modeling of Forest Road Networks and Their Effect on Stream Macroinvertebrate Communities
… in the Hydrologic Engineering Center Hydrologic Modeling System (HEC-HMS) runoff and routing model, in order to characterize the spatial distribution of potential road runoff impacts within the study areas. Ten macroinvertebrate metrics sensitive to sedimentation (i.e. % Intolerant Taxa, …

Conservation genetics and population status of the Flame Chub, Hemitremia Flammea
… Further analyses using microsatellites and geospatial modeling would refine these results. Species like H. flammea are indicators of the health of groundwater resources that are under increasing anthropogenic pressure.

Identifying Healthcare Access and Enhancing Geospatial Analysis with Generative AI
This thesis brings together geospatial modeling and generative artificial intelligence to address healthcare accessibility and automation of spatial analysis. The first study examines disparities in dental care access across six regions of Virginia by comparing driving and public transit modes for …

Predicting and Equipping Private Well Owners at Risk of Microbial Contamination After Flooding Events in the Alabama Black Belt
… contamination in shallow groundwater wells and geospatial modeling was used to characterize flooding risk across the Black Belt. The compilation of available and reliable resources into a single-point source will aid in educating and equipping well owners to reduce their exposure to microbial …

Implementation and simulation of mobile sensor networks for nuclear radiation detection
… are studied and quantified. Next, focusing on geospatial modeling of radiation count data, Poisson kriging is proposed to estimate the background radiation level and perform anomalous source detection. The proposed method is validated using simulated source data injected in measured background …

Assessing vulnerability and multi-hazard risk in the Nepal Himalaya
… of Dharan, Nepal, is presented. Freely available geospatial data in combination with socio-economic data collected from local government and secondary sources are used. Multi-hazard risk assessment is data intensive and requires considerable financial and human resources, which are lacking in …

Representing complex multisector, human systems into land use and land cover mapping to inform sustainability and future societal development.
… resolutions. The novelty of Multi-Sector Dynamic modeling is its ability to characterize muti-sectoral information spatially within the physical landscape. When sectoral information is put in a spatial context, it allows research to access unique perspectives on spatial consequences. This is …

Bionomics of Ochlerotatus triseriatus Say (Diptera: Culicidae) and Aedes albopictus Skuse (Diptera: Culicidae) in emerging La Crosse virus foci in Virginia
Recently, the number of human cases of La Crosse encephalitis (LACE), an illness caused by mosquito-borne La Crosse (LAC) virus, has increased in southwestern Virginia, resulting in a need for better understanding of the virus cycle and the biology of its vectors in the region. This project …

Estimating Hg Risk to the Common Loon (Gavia immer) in the Rangeley Lakes Region of Western Maine: A Regression Based GIS Model
This research relates Hg levels in the Common Loon (Gavia immer) to a variety of physical factors. Constructed within the framework of a GIS system, this model analyzes the spatial relationships and the influence of physical land cover factors as a function of distance from the individual loon …

Surface Spills Associated with Oil and Gas Activities in Saskatchewan and Potential Impacts to Shallow Groundwater Resources
… 1990 to 2019. Multiple regression analyses and geospatial modeling were applied to the spilled volumes to correlate their variability to the production intensity and analyze how these relationships vary spatially. The potential environmental risk of produced water (PW) spills was evaluated by …

HYDRAULIC, GEOSPATIAL, AND SOCIOECONOMIC MODELING OF STRATEGIC FLOODPLAIN RECONNECTION TRADEOFFS ALONG THE LOWER TISZA RIVER (HUNGARY) AND LOWER ILLINOIS RIVER (ILLINOIS, U.S.A)
… border. A novel framework using hydrodynamic and geospatial modeling was used to perform planning-level evaluations of the tradeoffs between floodplain-reconnection scenarios and enhancement of the existing levee system. The scenarios evaluated include levee removal and levee setbacks to …
