Publications

Assessing the spatial distribution of invasive species is a critical component for establishing baselines to examine the rate of spread, documenting key areas where negative impacts on ecosystems can be mitigated, and developing sustainable management strategies. Callery pear (Pyrus calleryana Decne.; PC) is a rapidly spreading invasive woody plant species in the eastern United States (U.S.). The incursion of these wild-type trees into urban, peri-urban, and rural landscapes, which have escaped from transplanted clonal cultivars, poses complex management challenges for land managers and hampers ecosystem function by competing with native plant species and altering the forest environment. We integrated …

Stream Temperature Responses To Summer Urban Rain Events Along The Savannah River, Joseph E. Wermter, Vivian L. Turner, Max K. Appelbaum, James M. Shepherd, Jacob Z. Lott

Journal of South Carolina Water Resources

The hydrological urban heat island (HUHI) is a recent facet of the urban heat island (UHI), describing thermal enhancement of bodies of water in response to urbanization. Although the forefront of this work has been studied for large Metropolitan areas, this effect on developing cities is currently unknown. To locally measure and quantify HUHI effects in a developing city, we utilized Multi-Radar Multi Sensor (MRMS) radar-derived rainfall data to estimate rainfall in the Augusta Metropolitan Area (AMA) and the Savannah Metropolitan Area (SMA), two developing communities adjacent to the Savannah River. We analyzed mean temperature trends of two stream gauges …

Irrigation Scheduling Methods: Checkbook Vs Fao-56, Adarsha Neupane, Vidya Samadi

Forestry and Natural Resources

Irrigation scheduling addresses two critical questions: when to irrigate and how much water to apply. Providing the optimal amount of water at the right time enhances water use efficiency, leading to improved crop production, while minimizing water losses and ensuring sustainable water management. This article compares two widely used soil water balance-based irrigation scheduling methods—Checkbook and FAO-56—by evaluating their principles, advantages, and limitations, with a focus on how each method tracks and manages soil moisture. To illustrate their differences, we present example calculations demonstrating how each method estimates irrigation timing and amount. The Checkbook method, widely adopted for its simplicity, …

Culturally Responsive Stem Education: Integrating Mapping Techniques And Drone Technology For Youth, Mayra Rodriguez Gonzalez, Kevin G. Torres Garrido

Journal of Youth Development

Integrating drone and geospatial technologies with participatory techniques offers a promising approach to culturally responsive STEM education. However, these areas are rarely combined in existing literature. Drone and geospatial education for youth generally focuses on technical skills, while participatory methods in youth-led initiatives often aim to foster community connection and a sense of place. Unfortunately, these approaches typically exist in isolation within youth programming. This disconnect limits the potential to engage underrepresented youth in STEM by not linking spatial data to local contexts and culturally meaningful narratives. By combining these approaches, both technical learning and personal engagement could be enhanced, …

An Inference Approach For Assessing Place-Based Vulnerability To Heat Mortality, Junkang Xu, Chao Fan, Xing Xu, Haoying Han

Publications

A global increase in the frequency, severity, and scale of extreme heat raises concerns about human vulnerability to climate change and associated mortality. Heat vulnerability and mortality have largely been studied separately, lacking an understanding of their causation. Here, we create a non-parametric generalized inference approach that links socioeconomic, environmental, and infrastructure factors articulated in vulnerability theory and heat mortality between 2010 and 2020 for counties across the United States. We find that the lack of vegetation coverages drives mortality in the Southern U.S. and among Hispanic people. Limited air conditioning is a key factor in heat-related mortality among White …

Multi-Stage Stochastic Programming For Disaster Relief Logistics Under Forecast Uncertainty, Sudhan Bhattarai

All Dissertations

Hurricanes are among the most destructive annual disasters in the United States, presenting interdependent challenges for evacuation planning and relief-supply logistics. Coordinating evacuation and relief operations is crucial to ensure the timely and effective movement of at-risk populations and the delivery of essential supplies. This dissertation develops and evaluates three progressively advanced multi-stage stochastic programming (MSSP) frameworks that integrate evacuation and relief-item pre-positioning while explicitly accounting for uncertainty in hurricane forecasts.

Chapter 1 introduces a fully adaptive MSSP model for the integrated hurricane relief logistics and evacuation planning (IHRLEP) problem. The model simultaneously optimizes evacuation flows and inventory pre-positioning over …

Development Of A Homogenized Material Model For Carbon Fiber–Aluminum Transition Joints Using Fea And Optimization, Nicholas M. Couch

All Theses

The integration of metals and composites in automotive structures improves manufacturability and overall structural performance. The proposed Ultrasonic Additive Manufacturing (UAM) joint provides a promising solution for joining aluminum and carbon fiber; however, modeling its behavior across an entire vehicle can be computationally expensive. To address this challenge, a homogenized material card is developed to efficiently capture the joint’s mechanical response while maintaining computational efficiency. A novel characterization method is implemented, employing implicit simulations and optimization techniques to determine the effective material properties of the UAM transition joint. This approach enables rapid iteration of material parameters, facilitating the efficient evaluation …

Impact Of Activated Carbon On In-Situ Reductive Dechlorination Of Chlorinated Ethenes In The Presence Of Perfluoroalykl Substances, Katie Motta
