Roughness and geometry effects of engineered log jams on 1-D flow characteristics

Creator:: Valverde, Rachelle S.
Abstract:: The re-introduction of large woody debris (LWD) into streams and rivers for stream restoration purposes is rapidly growing. Engineered log jams (ELJs) are man-made structures intended to mimic natural LWD structures, designed and installed to protect stream banks from erosion while increasing habitat diversity. Several studies have evaluated the flow...

Mapping Nearshore Bathymetry with Spaceborne Data Fusion and State Space Modeling

Creator:: Forfinski-Sarkozi, Nicholas A.
Abstract:: Despite numerous techniques for measuring and estimating water depth, bathymetry in the nearshore zone is notoriously difficult to map. Dangerous sea states, noisy environmental conditions, and expensive survey operations, particularly in remote areas, contribute to the difficulties of obtaining data along the coast. Global datasets, derived mainly from satellite altimetry...

Vertical jet diffusion in non linear density stratified fluid

Creator:: Baumgartner, D. J. (Donald John), 1933-
Abstract:: The simplified equations of motion proposed by Morton to determine the extent of vertical travel of a forced plume in a linear density stratified environment were re-written and solved in a way which allowed them to be applied to any non linear profile of density. For application to any specific...

Cross-Laminated Timber Shear Walls with Toe-Screwed and Slip-Friction Connections

Creator:: Fitzgerald, Dillon M.
Abstract:: Timber engineering is currently in the midst of a significant evolution due to the rise of mass timber products, like cross-laminated timber (CLT). Increasing numbers of structural engineers are facing the challenge of designing lateral-force-resisting systems (LFRS) for multistory CLT structures. LFRS solutions such as steel frames, concrete cores, or...

A preliminary assessment of post-fire dissolved organic carbon concentrations in the McKenzie River basin, Oregon

Creator:: Hyatt, Charles
Abstract:: In recent decades, the occurrence of large, high severity wildfires has increased substantially in many parts of the world, including the western United States. These fires have the potential to impact water quality, aquatic ecosystems, and downstream communities for many decades. As such, it is increasingly important to understand the...

Design criteria for waste water lagoons in Oregon

Creator:: Putnicki, George John
Abstract:: Waste water lagoons have been used as a satisfactory means of treating domestic and certain industrial wastes in many parts of the country. Many of the parameters that govern the applicability of this type of treatment process are climatic in nature, and critical evaluation of local climatic conditions, as well...

Relationships between seasonal suspended sediment behavior and reservoir turbidity

Creator:: Conner, Dan Alan
Abstract:: The causes of turbidity in impounded and released reservoir water are studied. Seven Willamette Basin reservoirs are compared to isolate watershed and reservoir characteristics which produce variations in turbidity. Of the seven, Hills Creek Reservoir is examined in detail. Particular features of the basin and impoundment are studied to isolate...

Behavior of stream inflows to a stratifying field reservoir

Creator:: Chasse, James Peter
Abstract:: The behavior of a stream upon entering a field reservoir was studied at various stages of stratification. The principal field techniques included fluorometric and temperature surveys. General relationships were obtained, between dimensional and locational characteristics of the inflow current and the thermal structure of the impoundment. As predicted by analytical...
