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 given thesis/dissertation in DRUM.

More information is available at Theses and Dissertations at University of Maryland Libraries.

    Circulation and Transport Processes for the Pocomoke River: A Tibutary to Partially Mixed Estuary
    (2005-12-12) Davis, Edgar Vernon; Boicourt, William C.; Marine-Estuarine-Environmental Sciences; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
    One and two-dimensional box models were used to estimate steady state single and two-layer gravitational circulation, transport, and residence times for the Pocomoke River, a tributary estuary on the eastern shore of Chesapeake Bay. Vertical salinity distribution in the narrow deep river varied from well mixed to stratified, both spatially and temporally. Comparison of estimated freshwater inputs to ADCP transport calculations indicates that the surrounding wetlands have the capacity to store and release a substantial amount of water to the river. The models are particularly useful in defining steady-state concentration distributions of dissolved conservative substances entering the river at a given flux. Spring and late summer residence times varied with river flow, as expected, from 52 to 102 days. The exception was 395 days during the summer drought of 1999.
