    Quantifying Galloway: Fluvial, Tidal and Wave Influence on Experimental and Field Deltas
    (2016-04) Baumgardner, Sarah
    Deltas are some of the most densely settled landscapes on Earth and are of the utmost importance economic and agricultural importance. Human use of these areas is threatened by climate change, and our future management of them will benefit from increased understanding of their response to the energy regimes that shape their planform morphology. We present a series of experiments on experimental deltas in which we study the link between impinging tide and wave energy and measures of delta geometry as well as an application of these metrics to a large dataset of images of deltas in the field.

    Study of Behaviors of Single Large Intruders in Bulk Flow
    (2009-04-08) Sun, Zhen
    Understanding the fundamentals of granular flow is crucial to industrial applications. Good examples are found in processing pharmaceutical pills and ceramic powders. Mixing granular materials is a major concern for engineers who process granular materials. Developing sensor particles to track the flow of granular materials is a good way to understand the characteristics of granular flow. In order to facilitate the development of sensor particles, it is crucial to understand how the sensor particles behave in bulk granular flow. This research was to study how a single intruder's (sensor) movement might be different than that of the bulk particles. In other words, this research is to understand the segregation process, so that details of this disparate movement could be used to predict the bulk behavior. Most of the segregation occurs in the vertical direction so that most parts of this research is focused on exploring the vertical segregation between intruders and matrix particles.
