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

    Our Wild: Architecture Catalyzing Ecological Revitalization of the Potomac
    (2018) Morris, Jake Sharlin; Williams, Brittany; Architecture; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
    As the global environment becomes increasingly unstable, our role in the ecosystem has become more critical than ever. By becoming stewards of the environment we can ensure a healthy world for future generations of humans and wildlife alike. This thesis will focus on the Potomac River ecosystem and how a center for conservation and wildlife rehabilitation can engage and educate the public with the ecosystem they rely upon so heavily. Architecture defines our physical environment yet its influence is not bound to humanity, rather it has a defining role and impact on the greater ecosystem. Developing a design that works to remediate its site while simultaneously instilling a sense of environmental empathy on a communal scale can successfully begin the imperative process of revitalizing the Potomac River.

    Into the Water: Cleansing the Nation's Symbolic River
    (2013) Hinkle, Nicole Adriene; Draper, Powell; Architecture; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
    This thesis proposes a center and attendant water cleansing systems that will simultaneously cleanse the waterways of the Potomac River in Washington D.C. through filtration and the removal of aqueous impurities as well as hosting research and exhibitions demonstrating ways humans can successfully improve the earths natural watershed systems. This particular example in our nation's capital will also provide recreation and education space for the community to learn about the health of water systems and feature global strategies to improve our watersheds in the symbolic landscape of the national mall and surrounding monumental landscape.

    EVALUATION OF THE INFLUENCE OF NITROGEN ON PRIMARY PRODUCTION USING RETROSPECTIVE DATA, REGRESSION ANALYSIS, AND MODELING
    (2012) Ziombra, Katherine Elizabeth Davis; Harris, Lora A; Marine-Estuarine-Environmental Sciences; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
    Anthropogenic activities have negatively affected water quality in the Chesapeake Bay and its tributaries. The Potomac River (PR), the largest tributary, is a primary study site for water quality research and new management strategies. The Blue Plains Wastewater Treatment Plant (BP), located in the tidal fresh portion of the PR, is the largest total nitrogen (TN) point source. Retrospective examination of water quality data for the PR revealed relationships among discharge, N loading and concentration, light and primary production. Regression analysis revealed BP (TN) load was an important variable influencing production, coupled with local dissolved inorganic nitrogen concentrations and photic depth prior to installation of biological nutrient removal (BNR) at BP. After 100% BNR implementation, BP TN did not influence production. Four existing primary production models were evaluated for applicability to tidal fresh systems. Regression analysis demonstrated all models were significant but the BZpI0t model provided the most robust results.
