Geomorphic controls on hyporheic exchange flow in mountain streams

Creator:: Kasahara, Tamao
Abstract:: Simulations of stream-subsurface water exchange (hyporheic exchange) using a three-dimensional steady state groundwater flow model and a particle tracking model in unconstrained and constrained reaches of small (2nd-order) and intermediate (5th-order) mountain streams were conducted to estimate the effects of geomorphic features on the extent, volume and residence time of...

Bulldozer blades and colliding submarine mountain chains : constraints on central Oregon convergent margin tectonics from magnetics and gravity

Creator:: Fleming, Sean W.
Abstract:: Magnetic and gravity modelling was completed along two E-W transects offshore central Oregon. These models indicate that the backstop-forming western edge of the Siletz terrane has a seaward dip of approximately 40° to 49° at 44°48'N, shallowing to ~28° at 44°1 1 'N. This is a well-determined result, given available...

Spatial and temporal characteristics of groundwater levels adjacent to beaver ponds in Oregon

Creator:: Sharps, Diana E.
Abstract:: This study was undertaken to evaluate the spatial and temporal characteristics of riparian groundwater tables adjacent to beaver ponds. The research was conducted in two parts; in the first portion a two-dimensional, finite-difference computer model was developed and utilized to simulate groundwater elevations through time in pond-adjacent aquifers. Two types...

Tsunami inundation : estimating damage and predicting flow properties

Creator:: Wiebe, Dane Michael
Abstract:: The 2004 Indian Ocean and 2011 Tohoku tsunami events have shown the destructive power of tsunami inundation to the constructed environment in addition to the tragic loss of life. A comparable event is expected for the Cascadia Subduction Zone (CSZ) which will impact the west coast of North America. Research...

Managing urban development : a simulation approach for coping with change at a municipal parking structure

Creator:: White, Stephen James
Abstract:: Public construction projects are frequently presented as occurring in complex social, political and economic settings described as being uncertain. In public administration, this uncertainty is cited as a cause for shifting from the so called "rational-comprehensive" model of policy and decision making toward an "incremental" or "mixed-scanning" approach. None of...

Development of Douglas-fir log quality, product yield, and stand value after repeated thinnings in western Oregon

Creator:: Christensen, Glenn A.
Abstract:: Forest managers are beginning to take an interest in management of young Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) in Western Oregon and Washington. Studies have established the relationship between growth and levels-of-growing-stock but few have established a link to wood quality and value. This study used data collected from a long...

A hydrogeologic study and groundwater model of Parrett Mountain, Oregon

Creator:: Healy, Robert Peter
Abstract:: This thesis presents a hydrogeologic study of the Parrett Mountain Region, located approximately 20 miles south of Portland, Oregon. The aim of the study was to investigate the impacts of Columbia River Basalt on the regional groundwater system, to expand our understanding of flow through fractured basalt, to improve management...

Agent-based Tsunami Evacuation Model : Life Safety and Network Resilience

Creator:: Mostafizi, Alireza
Abstract:: Natural disasters could result in unnecessary loss of life and disproportionate suffering to families and communities if evacuation plans are not in place or understood by the public. In the Pacific Northwest, a magnitude 9.0 earthquake and tsunami from the Cascadia Subduction Zone (CSZ) represents one of the most pressing...

Basin-wide distributed modeling of hydrologic responses to irrigation management in the Wood River Basin, Klamath County, OR

Creator:: Owens, Joshua M.
Abstract:: The Wood River Basin lies upstream of Upper Klamath Lake, the main reservoir of the USBR Klamath Irrigation Project that provides irrigation water to 210,000 acres of downstream land. Water allocation became a contentious issue in 2001 when drought led to curtailment of irrigation deliveries to the Klamath Irrigation Project...
