Joint Failure Probability Of Dams Based On Probabilistic Flood Hazard Analysis, Matthew G. Montgomery
Joint Failure Probability Of Dams Based On Probabilistic Flood Hazard Analysis, Matthew G. Montgomery
Masters Theses
Probabilistic risk methods are becoming increasingly accepted as a means of carrying out risk-informed decision making regarding the design and operation of structures such as dams. Probabilistic risk calculations require the quantification of epistemic and aleatory uncertainties not investigated through deterministic methodologies. In this hydrological study, a stochastic sampling methodology is employed to investigate the joint failure probability of three dams in adjacent, similarly sized watersheds within the same Hydrologic Unit Code (HUC) 6 basin. A Probabilistic Flood Hazard Analysis (PFHA) framework is used to simulate the hydrologic loading of a wide range of extreme precipitation events across the combined …
Evaluating Current And Future Potential Distribution Of Epiphytic Orchids In The Congo Basin With Ecological Niche Models, Michael L. Ngoh
Evaluating Current And Future Potential Distribution Of Epiphytic Orchids In The Congo Basin With Ecological Niche Models, Michael L. Ngoh
Masters Theses
The Congo Basin Forest harbors a rich diversity of epiphytic communities, with the Orchidaceae alone making up more than 50% of all epiphytes in the region. Despite the huge diversity of epiphytes, many species, including epiphytic orchids, are at risk to a diverse array of threats. Climate change for instance poses severe threats to epiphytic orchids due to elevated temperatures, prolonged periods of droughts, as well as reduced rainfall across the Congo Basin Forest. In this study, we used ecological niche modeling and GIS techniques to identify spatial patterns of species richness, potential future climate refugia, and novel climatic suitability …
Impacts Of Summer Drought And Climate Change Conditions On Hydropower Resources And Power System Reliability In The Pjm Region, William J. Tingen Ii
Impacts Of Summer Drought And Climate Change Conditions On Hydropower Resources And Power System Reliability In The Pjm Region, William J. Tingen Ii
Masters Theses
The United States power grid is a large, complex, and interconnected system that involves the coordination of numerous entities (e.g., power plant owners/operators, regulators, stakeholders, etc.). As such, any type of extreme event can potentially threaten the economic, safe, and reliable operation of the grid. One such example is summer drought (i.e., events predominantly characterized by elevated temperatures and reduced precipitation), which have impacts spanning all aspects of the power system, especially generation resources through changes in water availability and temperature. Additionally, although heavily dependent on region, climate change can potentially increase the likelihood and severity of drought conditions, illustrating …
The Great Delusion, Beth Johnston
The Great Delusion, Beth Johnston
Masters Theses
The climate crisis is a wicked problem that poses many obstacles for action and understanding. This thesis is a non-linear accumulation of academic essays, interpolated with lists, anecdotal observations, data, and artwork that together explore the entanglements and complications of the climate crisis and my journey in making artwork as a response to those complications. The thesis surveys six bodies of artwork created over the course of graduate school, which use photography, sculptural installation, performance, and video to illustrate various topics and methodologies. Grounded in research on environmental justice, this essay explores temporal disjunctures, climate data encounters, the decolonization of …
Coping With Climate Change, Andrea Yj Mah
Coping With Climate Change, Andrea Yj Mah
Masters Theses
Climate change is a source of anxiety and stress. To be resilient to the changes that are occurring, individuals must cope with that stress. Because there are many ways that people might manage stress we examined variation in coping strategy use among Americans who reported some concern about climate change to understand generally how people cope with such stress, and whether it can be predicted from individual difference factors, namely degree of climate change concern and political ideology. We examined these variables specifically because in the study of responses to climate change, conservatives and liberals often report divergent beliefs, attitudes, …
Utilizing Climate Change Refugia For Climate Change Adaptation And Management In The Northeast, Sara A. Wisner
Utilizing Climate Change Refugia For Climate Change Adaptation And Management In The Northeast, Sara A. Wisner
Masters Theses
To account for the effects of climate change, management plans in the northeast need to incorporate climate adaptation. Conserving climate change refugia is one adaptation strategy. Climate change refugia are areas buffered by climate change that enable the persistence of valued physical, ecological, and cultural resources; preserving these areas could be a potential adaptation strategy. Using a translational ecology approach where researchers and managers from the National Park Service, US Geological Survey, the University of Massachusetts, and elsewhere worked together, we focused on identifying refugia for tree, herbaceous plant, mammal, and bird species in order to prioritize them for conservation …
A Tipping Point In The Ecuadorian Amazon Rainforest: Current And Future Land-Use And Climate Change Trends, Alula Shields
A Tipping Point In The Ecuadorian Amazon Rainforest: Current And Future Land-Use And Climate Change Trends, Alula Shields
Masters Theses
Many regions of the Amazon are experiencing drastic changes as deforestation and climate change drive the world’s largest continuous rainforest towards a ‘tipping point’. These disturbances are changing natural cycles that once past a critical threshold, will mark an unstoppable transition to an altered ecosystem. Losing areas of the Amazon rainforest will have implications for the global climate, global carbon budget, and global hydrological regimes. Scholars have projected these tipping points for areas of the eastern Amazon rainforest, but much less scholarship focuses on the headwaters of the Western Amazon, an area of great cultural and biological importance. Ecuador is …
