The effect of mixing on the oxygen uptake rate of estuarine bottom deposits

Creator:: Martin, Duane Collins
Abstract:: A study of the effect of mixing on the oxygen uptake rate of estuarine bottom deposits is presented. The method of study involved the mixing of samples of bottom deposits with the overlying water to result in concentrations of suspended matter in the same order as observed in the estuary....

In situ measurement of the benthal oxygen requirements of tidal flat deposits

Creator:: Crook, Gene Ray
Abstract:: In situ light and dark planktonic and benthal respirometers were used to measure the oxygen requirements of Yaquina estuary water and benthal deposits. Respirometer devices were constructed so that actual conditions of mixing could be simulated and benthal deposit disturbance would be minimized. A mathematical model of a benthal respirometer...

Development of structural layer coefficients for open graded asphalt emulsion mixes

Creator:: Hatch, David Russell
Abstract:: This paper describes the development of structural layer coefficients for open graded asphalt emulsion surfacing layers which can be used with the AASHO pavement design method, as modified by the U. S. Forest Service, Region 6. A field survey conducted to document the history, performance and material characteristics of in-service...

Engineering Services of Submerged Aquatic Vegetation (SAV): Investigation of the Land-Building and Energy-Attenuating Properties of SAV Habitats Across Spatial Scales

Creator:: Holzenthal, Elizabeth R.
Abstract:: Submerged aquatic vegetation (SAV) species, such as seagrasses, are highly valued in estuaries because of the many economic, ecological, and cultural services that they provide, including shelter for fisheries, minimizing water turbidity, and improving am-bient water quality. SAV can also alter its physical environment by attenuating wave and current velocities,...

Evaluation of system effects and structural load paths in a wood-framed structure

Creator:: Martin, Kenneth G.
Abstract:: The objective of this project was to develop an analytical model of a light-framed wood structure using a prevalent structural analysis computer program in order to evaluate system effects and define load paths within the structure, especially under extreme wind events. Simplified modeling techniques and material definitions were developed and...

Sustainable construction safety and health rating system

Creator:: Rajendran, Sathyanarayanan
Abstract:: The main objective of this research study is to incorporate construction worker safety and health into sustainable design and construction practices. This can be fulfilled by the development of an innovative construction worker safety and health planning tool, called Sustainable Construction Safety and Health (SCSH) Rating System that will: •...

The Art of Reducing Coastal Hazard Complexity: Coupling Physics and Probability to Understand Extremes, Variability, and Climate-dependence

Creator:: Anderson, Dylan L.
Abstract:: Coastal hazards are the result of numerous physical processes cumulatively causing water levels to flood and erode the land. The waves, storm surges, tides, and run-off contributing to elevated water levels are each the product of chaotic and random weather patterns. These stochastic weather patterns dissipate energy in Earth's climate...

Investigating the Current Teaching Evaluation Practices used in Engineering Programs and their Usefulness to Educators

Creator:: Villanueva, Keisha A.
Abstract:: Evaluation of teaching is used to examine and improve teaching quality in higher education. The literature consists of best teaching evaluation practices that have been developed, yet there is little research that has been conducted which investigates teaching evaluation practices in engineering programs. This thesis represents two manuscripts that explore...

Practical modeling for load paths in a realistic, light-frame wood house

Creator:: Pfretzschner, Kathryn S.
Abstract:: The objective of this study was to develop and validate practical modeling methods for investigating load paths and system behavior in a realistic, light-frame wood structure. The modeling methods were validated against full-scale tests on subassemblies and an L-shaped house. The model of the L-shaped house was then modified and...

Observations and prediction of intermittent sediment suspension in the surf zone

Creator:: Yoon, Hyun Doug
Abstract:: In this dissertation the interactions between hydrodynamics, sediment suspension and transport, and morphological evolution in the surf zone was investigated with a large-scale laboratory experiment data, CROss-Shore Sediment Transport Experiment (CROSSTEX). The data set included comprehensive measurements of water surface elevation, fluid velocity, sediment concentration, and morphology for irregular waves...
