Chaos in a long rectangular wave channel

Creator:: Bowline, Cynthia M.
Abstract:: The Melnikov method is applied to a model of parametrically generated cross-waves in a long rectangular channel in order to determine if these cross-waves are chaotic. A great deal of preparation is involved in order to obtain a suitable form for the application of the Melnikov method. The Lagrangian for...

Application of the generalized Melnikov method to weakly damped parametrically excited cross waves with surface tension

Creator:: Fadel, Suzan M.
Abstract:: The Wiggins-Holmes extension of the generalized Melnikov method (GMM) is applied to weakly damped parametrically excited cross waves with surface tension in a long rectangular wave channel in order to determine if these cross waves are chaotic. The Lagrangian density function for surface waves with surface tension is simplified by...

Summertime water temperature trends in Steamboat Creek Basin, Umpqua National Forest

Creator:: Holaday, Steven A.
Abstract:: The Steamboat Creek basin drains 227 mi² (588 km²) of steep forested terrain into the North Umpqua River of Southwest Oregon, 39 mi (63 km) northeast of Roseburg. Summer base flows for Steamboat Creek average 83 cfs (2.35 m³/sec). Steamboat Creek and its tributaries are considered important to the production...

Dynamics of the nearshore wave bottom boundary layer

Creator:: Foster, Diane Lyn
Abstract:: This thesis presents an examination of the nearshore wave bottom boundary layer under conditions of significant sediment response. Using both field observations and simple models, the response of the bottom boundary layer to random waves is shown to have a complex behavior. First, the linearized wave bottom boundary layer governing...

Indirect parameter identification algorithm in radial coordinates for a porous medium

Creator:: Roley, Kenneth L.
Abstract:: The decision to bury high level nuclear wastes in deep geological formations led to the study of the Hanford Nuclear Reservation as one of three possible sites for the first nuclear waste repository in the United States. To adequately evaluate the environmental impact of siting nuclear waste repositories in basalt...

Low volume grade crossing treatments for the Oregon high speed rail corridor

Creator:: Zaworski, David D.
Abstract:: This study defines the information gathering and communication and response needed for safety at highway-rail crossings. It examines technologies for low-cost, high-safety treatments for low volume highway crossings of higher speed (130-200 kph) rail. Crossing closure and consolidation is a necessary first step. Existing train control and crossing safety systems...

Down-borehole permeable barrier reactor : verification of complete mineralization of pentachlorophenol in a sequential anaerobic-aerobic process

Creator:: Roberts, David Bradley
Resource Type:: Masters Thesis
Full Text:: chlorophenol additions resulted in a final concentration of 1.94M (0.5 mg/L) PCP or 1.9p,M (0.5 mg/L) UL-14C

Evaluation of crumb rubber modified mixtures using performance based analyses

Creator:: Saxton, Robert W.
Abstract:: This study investigated the laboratory performance of crumb rubber modified mixtures compared to a standard bituminous mixture using performance based test procedures. This study was part of an asphalt resurfacing program for the Seattle Washington area. Laboratory analyses were used to estimate the long term pavement performance of these mixtures...

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...
