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...

Flow slide control with slope revetments

Creator:: Narkiewicz, Steven Arthur
Abstract:: This paper examines the response of submerged model sand slopes to vibration and the beneficial effects of placing rock revetments on the face of the slope to prevent flaw slides. Pore water pressure response and deflection were used as a criteria for stability in an attempt to relate stability with...

Changes in hyporheic exchange flow following experimental large wood removal in a second order, low gradient stream, Chichagof Island, AK

Creator:: La Nier, Justin
Abstract:: Hyporheic Exchange Flow (HEF) is driven by head gradients defined by the hydro-topography of the stream surface, which is controlled by the particular geomorphology of the stream. We quantified the impact of large wood, which typically exerts a strong control on stream morphology, on HEF in a second order, low...

Alkali-silica reaction in concrete containing recycled concrete aggregates

Creator:: Adams, Matthew P.
Abstract:: Using recycled concrete aggregate (RCA) as a replacement for natural aggregate in new concrete is a promising way to increase the overall sustainability of new concrete. This has been hindered, however, by a general perception that RCA is a sub-standard material due to the lack of technical guidance, specifically related...

The static and dynamic analysis of discretely represented moorings and cables by numerical means

Creator:: Dominguez, Richard Frank
Abstract:: Computer oriented techniques and procedures are presented for the analysis of single and multiple cable systems. Application is made to a two-point mooring system influenced by surface and subsurface hydrodynamic loading. The effects of the various parameters are presented and the numerical method is compared to exact solutions obtained from...

Investigation of the behavior of diagonally cracked full-scale CRC deck-girders injected with epoxy resin and subjected to axial tension

Creator:: Smith, Matthew T. (Matthew Todd)
Abstract:: Article 1: Behavior of Epoxy Injected Diagonally Cracked Full-Scale CRC Deck-Girders. Many cast-in place reinforced concrete deck-girder bridges (RCDG) remain in the national inventory and exhibit diagonal cracking. Epoxy injection has been in use for several decades as a method for sealing diagonal cracks, but the effects on girder behavior...

New acoustic emission applications in civil engineering

Creator:: Schumacher, Thomas
Abstract:: Non-destructive testing methods and applications have become of increasing interest due to the worldwide aging and deteriorating infrastructure network. In the field of Civil Engineering, bridges and bridge components as well as non-structural elements such as roadway pavements for example, are affected. In particular, the Acoustic Emission (AE) technique offers...

Assessment of Multi-year Hydrologic Performance of Bioretention Facility using Real-Time Sensors

Creator:: Alyousef, Hashim A.
Abstract:: Bioretention facilities are emerging as a popular way to deal with stormwater runoff in urban environments and address its concerns. Real-time sensors installed in bioretention facilities aid in understanding the performance and feasibility of such facilities over time. A bioretention facility in Corvallis, Oregon was monitored for a study period...

Implications of Red Signal Countdown Timers on Visual Attention of Oregon Drivers

Creator:: Wyman, Amy A.
Abstract:: Red Signal Countdown Timers (RSCTs) are devices placed at intersections to inform drivers of the time remaining on a red indication before it turns green, typically to improve intersection efficiency. This study examines the visual attention of Oregon drivers to circular red (CR) indications with RSCTs as compared to standard...

Student Engagement : Exploring How and Why Students Engage In- and Out-of-Class

Creator:: Pascoe, Jason J.
Abstract:: Student engagement in a course plays a vital role in a student’s ability to process and construct knowledge. Student engagement research has investigated how students engage in and out of the classroom on a macro scale, through observation and survey data collection of large student populations, which lack focus on...
