Streambed scour and redeposition behavior in streambed simulated culverts over an annual period

Creator:

Stewart, Anna

Abstract:

The objective of this study was to provide first order observations of bed level changes occurring in streambed simulated culverts throughout an annual period. To accomplish this, 30 culvert sites were selected in Oregon and Washington, and monitored over, at least, a 2 year period. Streambed scour and redeposition data...

Numerical investigation of aggregate trench-reinforced clay ground improvement to increase bearing capacity of continuous strip foundations

Creator:

Walter, Jakob R.

Abstract:

Compacted aggregate trenches are a method of soil improvement that could be substituted for commonly used aggregate piers in certain geometrical arrangements of shallow foundations. However, this type of ground improvement has little research to support the understanding of their contribution to improved strength of an unimproved clay soil. This...

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...
