New submissions to the thesis/dissertation collections are added automatically as they are received from the Graduate School. Currently, the Graduate School deposits all theses and dissertations from a given semester after the official graduation date. This means that there may be up to a 4 month delay in the appearance of a give thesis/dissertation in DRUM

    WHEN ROADS WANT TO BE DAMS: LOOKING TO DAM SAFETY TO REGULATE TRANSPORTATION EMBANKMENTS
    (2022) O'Shaughnessy, Amanda; Davis, Allen P; Aydilek, Ahmet H; Civil Engineering; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
    The potential for various failure processes impacting transportation embankments temporarily impounding water has not been a common consideration in the design and management of these structures. However, changes in water elevations due to land development and climate change has prompted concern about impoundment on seepage rates and overall stability of the constructed embankments. The goal of the research was to examine how different aspects of dam safety can be incorporated in transportation embankment management. Current U.S. Mid-Atlantic state policies were summarized, evolving issues pertaining to water impoundment were investigated, transportation and dam embankments were compared, and seepage and slope stability numerical modeling were conducted to understand how example transportation embankments behave under various water impoundment scenarios. Performance assessment of granular materials commonly used in transportation embankments indicates their ability to withstand piping erosion but poor slope stability during rapid drawdown. Results demonstrate the need for infrastructure inventories and hydrologic research on this topic.
