Throughout many of the world’s mountain ranges snowpack accumulates during the winter and into the spring, providing a natural reservoir for water. As this reservoir melts, it fills streams and recharges groundwater for over 1 billion people globally. Despite its importance to water resources, our understanding of the storage capacity...
In the Pacific Northwest, USA, the extraordinarily low snowpacks of winters 2013–2014 and 2014– 2015 stressed regional water resources and the social environmental system. We introduce two new approaches to better understand how seasonal snow water storage during these two winters would compare to snow water storage under warmer climate...

The nature of upper plate deformation along the Cascadia subduction zone (CSZ) is poorly understood. Systematic covariation among topographic relief, geodetically determined uplift rates, decadal to millennial erosion rates, and the frequency of episodic tremor and slip (ETS) along the Cascadia forearc suggest a genetic association between forearc topography and...
The Panamint Valley fault zone (PVFZ) is an active, dextral-oblique normal fault that partially accommodates dextral shear across the Eastern California Shear Zone (ECSZ). The fault system has a complex geometry, characterized by a relatively high-angle dextral oblique normal fault in the south and a low-angle detachment system that accommodates...

ABSTRACT
This thesis describes the results
Re-establishing connectivity is a primary restoration activity for enhancing the
recovery of migratory fishes, but actions are often limited by lack of funds and
understanding of the benefits of individual projects. The objective of this study was to
develop a Bayesian Network (BN) to assess priorities for restoration of aquatic...
During the U.S. military interventions in Nicaragua, the Dominican
Republic, and Haiti between 1915 and 1934, Washington equipped
members of the its armed forces with civil and political powers that
represented a radical departure from the North American military tradition.
This abandonment of tradition decisively contributed to both the
disappointments...
With an estimated 5.4 million Americans living with Alzheimer’s disease facing
individual, social, and financial burdens, researchers must make cognitive assessment inquiries a priority (Alzheimer’s Association, 2016). Cognition encompasses multiple aspects of thought
processes, such as multiple types of memory, planning, inhibitory control, attention, and
processing speed. The higher level...

In a steady state, the Earth's absorbed solar radiation (ASR) balances the outgoing
longwave radiation (OLR) at the top of the atmosphere (TOA). In response to a radiative
forcing, that is, an external perturbation to the top of the atmosphere energy balance, the
Earth's climate system adjusts until reaching a...
