The Marcellus Shale Natural Gas play in Pennsylvania, since its inception, continues to be a source of contention for multiple Pennsylvania stakeholders. The issues that relate to natural gas extraction have seemingly impacted every community within the Marcellus Shale region in some form. As in most common pool resource...
The current and potential benefits of using geographic information systems (GIS) to support state-level and regional-scale ocean management in the United States are evaluated. Specifically, the role of GIS in facilitating improved integration of management strategies for a variety of resource use issues across multiple management jurisdictions is examined, along...
Urban rivers with a history of industrial use can exhibit spatial and temporal variations in contaminant concentrations that may significantly affect risk evaluations and assessment of remediation efforts. To more effectively estimate human and ecological health risks, we evaluated the spatial and temporal distribution of polycyclic aromatic hydrocarbons (PAHs) in...
Across Oregon and other PNW states thousands of miles of rivers, streams and adjacent wetlands are chronically de-watered as a result of over-appropriated water rights. In Montana alone, chronic or periodic de-watering occurs in over 4,000 miles of streams across 381 different river or stream systems. The ecological harm resulting...
The sinuous flight behavior of male Douglas-fir tussock
moths, Orgyia pseudotsugata, (McD.), is characterized by
positive anemotaxis and positive chemoklinotaxis and varies
depending on distance from the pheromone source, population
density, and time of day. Visual cues play a minor role
in close-range orientation to a pheromone source, but
males...
Transport in a binary stochastic media has been an area of interest for many applications over the past three decades. Many different methods have been attempted, most based on the Levermore-Pomraning coupled transport model. However, this method has never been able to correctly solve problems where a large amount of...

The intent of this work is to extend Implicit Monte Carlo Diffusion (IMD)[Gen.
2001] to account for frequency dependence and to incorporate the difference formulation[Szo. 2005] as a source manipulation variance reduction technique. This
work shows the derivation of the probabilities and the associated proofs which
govern the frequency dependent...
We investigate several aspects of the numerical solution of the radiative transfer
equation in the context of coal combustion: the parallel efficiency of two commonly used
opacity models, the sensitivity of turbulent radiation interaction (TRI) effects
to the presence of coal particulate, and an improvement of the order of temporal...
As of September 2020, three of the outputs mandated under the Streamflow Restoration Act have been completed. However, little has been done to assess the quality of these plans. By using the Characteristics of Plan Quality That Serve as Evaluation Criteria to evaluate the plans completed so far, this research...
This is a comparative analysis of groundwater conflict and surface water conflict in Idaho from 1950-2019. The work looks at Idaho's exceptional experience with water and demonstrates that water conflict in Idaho is different than in other PNW states. The work outlines that Idaho's water conflict is almost solely focused...
