The timing of two events in the early life history of coho salmon--emergence from
the gravel and entry into the ocean--is presumed to have evolved to ensure maximum
survival during these transition periods. Anthropogenic disturbances may disrupt the
timing of these events to the detriment of salmon populations.

This work investigates the acoustic velocity of gas-liquid mixtures in vertical, co-current flow in a concentric annulus. Acoustic velocity shows promise as a detection parameter for the presence and amount of gas in a liquid flow because of its high sensitivity to gas void fraction in a gas-liquid mixture. However,...
Soil solarization trials were conducted during the growing seasons of 2016-2018 with the purpose of determining if solarization was an effective pre-planting soil disinfestation technique for tree nurseries in the Pacific Northwest. A large data set was collected on soil properties and biological indicators from 5 interdisciplinary experiments. This thesis...
The concept of "adaptive governance" represents a spectrum of hybrid approaches to environmental governance employed to guide management of complex social-ecological systems under conditions of high uncertainty. While the concept of adaptive governance has benefited from over a decade of theoretical development, empirical examples of transitions towards adaptive governance are...
National statistics indicate that over ten thousand persons
each year become disabled from spinal cord-injury. The need for
research in this area is evident.
The objectives of this study were:
1. To determine any relationship between selected attitudes
and activity levels with self-concept;
2. To identify certain demographic variables that...
Over the past decade, the business sector has come under increasing pressure to improve their environmental, safety, and health (ESH) performance. This pressure has stemmed from both external and internal sources with the organization. Public image, legislative and regulatory requirements, stakeholder awareness of environmental performance, sustainable development, and changing corporate...
The Klamath Basin Restoration Agreement (KBRA) and the Klamath Hydroelectric Settlement Agreement (KHSA) forged between Klamath River Basin stakeholder groups in California and Oregon, when successfully implemented, will lead to the largest dam removal project in history. After a decade of intense legal and social conflict among disparate interests in...

Hypothetical power dissipation by a tidal in‐stream energy conversion device was calculated for Admiralty Inlet, Washington, a highly energetic entrance channel to Puget Sound and currently a candidate for tidal energy development. Power dissipation was calculated for a device of a given capacity as a function of hub height above...
