Modeling Neighborhoods As Fuel For Wildfire, Bryce Alan Young Jan 2025

Modeling Neighborhoods As Fuel For Wildfire, Bryce Alan Young

Graduate Student Theses, Dissertations, & Professional Papers

Wildfire models drive billions of dollars in risk mitigation efforts. However, the modeling community currently lacks a representative fuelscape on which to base simulations of fire spread in the built environment and the wildland-urban interface (WUI) where vegetation and structures act together as fuel for wildfire. This thesis advances wildfire risk modeling by addressing the underdeveloped representation of the built environment in existing frameworks. By identifying inconsistencies in how structure and defensible space features are defined and used across empirical studies, predictive indices, and fire spread models, this research lays the groundwork for standardized modeling approaches and feature selection (Chapter …

Investigating The Impact Of Aerial Firefighting On Rate Of Wildfire Spread, Lindsay Ann Wiard Jan 2025

Investigating The Impact Of Aerial Firefighting On Rate Of Wildfire Spread, Lindsay Ann Wiard

Graduate Student Theses, Dissertations, & Professional Papers

Aerial retardant drops are widely used in wildfire suppression, yet their effectiveness in slowing fire spread remains difficult to quantify at scale. This study evaluates the impact of aerial suppression on wildfire rate of spread (ROS) using a modeling framework that incorporates both observed (real) and counterfactual (synthetic) drop locations from a sample of 62 wildfires in Oregon. Synthetic drops were generated to simulate a no-suppression baseline, allowing us to compare changes in ROS in the presence and absence of suppression. We trained two random forest classifiers: one using both real and synthetic drops (the full model), and another using …

Investigating Non-Invasive Survey Methods And Building A Predictive Occupancy Model For Harlequin Ducks (Histrionicus Histrionicus) In Western Montana And Northern Idaho, Holli Ann Holmes Jan 2025

Investigating Non-Invasive Survey Methods And Building A Predictive Occupancy Model For Harlequin Ducks (Histrionicus Histrionicus) In Western Montana And Northern Idaho, Holli Ann Holmes

Graduate Student Theses, Dissertations, & Professional Papers

Harlequin Ducks (Histrionicus histrionicus; HADU) are an imperiled sea duck that breeds along white-water mountain streams, but challenges in surveying them have made it difficult to understand population trends in their Northern Rocky Mountain breeding population. In this study we had two objectives: (1) evaluate non-invasive survey methods for detecting HADU on their breeding grounds in Western Montana and Northern Idaho, and (2) develop an occupancy model to predict potential breeding stream use for HADU across the region. First, we assessed the efficacy of ground-based foot surveys (GBS), environmental DNA (eDNA), and camera traps to detect breeding HADU during …

Complexity, Polycentricity, And Climate Change: An Embedded, Multi-Level Case Study Of A Climate Meta-Network, Timothy Staub Jan 2025

Complexity, Polycentricity, And Climate Change: An Embedded, Multi-Level Case Study Of A Climate Meta-Network, Timothy Staub

Antioch University Dissertations & Theses

The earth is in crisis, and without urgent, systemic, and collective global action to address the emerging threat of climate change, we will continue to see catastrophic events impacting humanity, threatening our very survival in many regions of the world. Temperatures will rise, ice shelves will melt, seas will rise, crops will fail, water scarcity from drought and new weather patterns will increase and spread, wildfires will accelerate, and food and water insecurity, violence, and the largest human migration in history will ensue. These climate crises will displace over 1.2 billion people by 2050 at a rate currently exceeding 21.5 …

New Jersey's Mitigation And Adaptation To Climate Change: An Economic Analysis Of The State's Societal Benefits Charge And Community Solar Energy Program, Nicole S. Provost Jan 2025

New Jersey's Mitigation And Adaptation To Climate Change: An Economic Analysis Of The State's Societal Benefits Charge And Community Solar Energy Program, Nicole S. Provost

Theses, Dissertations and Culminating Projects

Understanding the current trajectory of New Jersey’s emissions and the existing legislation and programs implemented to help reduce emissions, it is evident that the State requires further actions to spur heightened emission reductions to reach its goals. One known impactful policy that could significantly accelerate this process is a carbon tax, which applies to emission-intensive goods. Although this policy does not currently exist in New Jersey, the State has a Societal Benefits Charge (SBC) that applies an approximate 3% charge to electricity and gas consumption on residential and commercial utility customers’ monthly energy bills, where revenues fund programs that offer …
